hippocampus writing life article

Thank you very much for these informative articles. For the rest of us, it is great to know that we can also benefit by “growing the gray matter” with regular, daily exercise. Following the reviewer's valuable suggestion, we further tested whether astrocyte activity is required for fear memory attenuation. Animals were randomly assigned to treatment groups. We don’t know exactly which exercise is best. We apologize for the confusion.

So why does the potential for high astrocyte calcium activity with local ATP-γ-S or MeSADP infusion not feed into the upstream mechanism for fear memory impairment? Most centers provide transportation from your home to the center. These results showed that the fear memory attenuation induced by astrocyte activation is present in both males and females. We thank the reviewer. These data indicate that when the adenosine level rises to reach a certain A1R occupancy threshold in vivo, a profound effect on memory can occur. What is missing is a definitive connection between astrocyte activation in fear conditioning and extinction under normal conditions. 2) Microdialysis experiments indicated an increase in adenosine from ~3 nM to ~3.5 nM following photostimulation. (If your work is more suitable for medRxiv, you will need to post the preprint yourself, as the mechanisms for us to do so are still in development.). What can we help you find? 3) The authors investigated the effects of ATP and ADP by infusing stable forms of these compounds (ATP-γ-S or MeSADP) into the hippocampus. Article citation count generated by polling the highest count across the following sources: Crossref, PubMed Central, Scopus. Even vacation is not an excuse; there’s still a lot of ways to do it! The following individuals involved in review of your submission have agreed to reveal their identity: Long-Jun Wu (Reviewer #2). That’s 120 minutes of moderate intensity exercise a week. The internal solution contained (in mM): 130 K-gluconate, 4 KCl, 10 HEPES, 4 MgATP, 0.3 Na2GTP, 10 Na2-phosphocreatine, and 0.3 EGTA. There are plenty of good reasons to be physically active. Big ones include reducing the odds of developing heart disease, stroke, and diabetes. In the present study, we found that photostimulation of astrocytes triggered increased ATP and adenosine concentrations in CA1. The back and abs are made up of several groups of muscles. Unlike the activation of metabotropic receptors by local ATP-γ-S or MesADP, the ChR2-induced [Ca2+]i elevation is the result of membrane channel-mediated Ca2+ entry from the extracellular space, but not from intracellular ER Ca2+ release. A more than acceptable to encourage this healthy habit that will bring us endless reasons benefits. Senior centers are providing more options for exercise, including exercise in or near a chair. However, both of these compounds in the mM range should certainly evoke large astrocyte calcium activity through Gq-coupled P2Y or ionotropic P2X receptors expressed on astrocytes. Cells were re-suspended in Dulbecco’s modified Eagle’s medium containing 10% fetal bovine serum and 10% Ham’s F-12 (all from Gibco) at a cell density of 20,000 mL−1. Due to the proximity to the plasma membrane where exocytosis occurs, transmembrane Ca2+ influx may be more efficient in inducing gliotransmitter release than Ca2+ release from intracellular stores (Chen et al., 2013; Tan et al., 2017; Yang et al., 2015). Li et al., present a well-written, well-organized and potentially impactful study on the role of astrocyte signaling in fear memory using optogenetic manipulation specifically in astrocytes. Interesting post. In a study done at the University of British Columbia, researchers found that regular aerobic exercise, the kind that gets your heart and your sweat glands pumping, appears to boost the size of the hippocampus, the brain area involved in verbal memory and learning. One would like to see control experiments in which other brain regions that are not involved in the learning task are stimulated to release adenosine. The plasmid was used as a template to repair the double-strand break by homologous recombination. These results demonstrated that hippocampal astrocyte activity is indeed required for contextual fear memory. The structure was first described by the anatomist Julius Caesar Aranzi. (A) Schematic of the experimental design for fear conditioning, photostimulation, and the subsequent test protocols. Does human growth hormone slow the aging process? Some older adults do not have a safe place to walk. Almost all of the research has looked at walking, including the latest study. Regards from Tot Dental. As the editors have judged that your manuscript is of interest, but as described below that additional experiments are required before it is published, we would like to draw your attention to changes in our revision policy that we have made in response to COVID-19 (https://elifesciences.org/articles/57162). The signals were filtered at 2 kHz using amplifier circuitry, sampled at 10 kHz, and analyzed using Clampex 9.0 (Axon Instruments). It is well established that adenosine lowers arousal. Super-ovulated female Sprague-Dawley rats were mated to Sprague-Dawley males, and fertilized embryos were collected from the oviducts. However, the chance of exposure to traumatic events such as military combat, disaster, and criminal violence is higher in males than females (Breslau, 2001; Parsons and Ressler, 2013). Statistical significance was set at p<0.05. Commenting has been closed for this post.

We thank Hui-Fang Lou and Li-Ya Zhu for technical support. These results showed that astrocyte activation specifically decreased contextual fear memory through the disruption of memory consolidation, suggesting that these cannot be the result of changes in arousal. These study participants walked briskly for one hour, twice a week. It is a small investment and well worth the extra cost. Contextual fear memory but not cued fear memory (Figure 2—figure supplement 1C and D) was significantly decreased in the photostimulated females. We thank the reviewer for these comments. Why do I smell certain odors that aren’t real? A large number of muscle groups are engaged in providing the spine the strength to support the body. 6) One of the major technical innovations in this study is to use the newly generated GFAP-ChR2-EYFP rats. On day 27, the rats were retrained in a new conditioning chamber, so the baseline freezing level was ~10%. The best advice you posted right there was to bring your own kit. Strong abdominal and back muscles can overcome any type of back pain, especially the ones which are caused by soft tissue injury or back muscle strain.When exercising, we tend to ignore the core area. Telemedicine: A good fit for cardiovascular care? These results have implications for therapeutics that modulate inhibition kinetics. So, we used an adeno-associated virus (AAV5) expressing human PMCA2w/b (hPMCA2w/b) with an astrocyte-specific GfaABC1D promoter to reduce hippocampal astrocyte Ca2+ signaling (Figure 2G and H). We have added the above statement to the Introduction in the revised manuscript. ARCHIVED CONTENT: As a service to our readers, Harvard Health Publishing provides access to our library of archived content. Thereafter, 20–25 embryos were transferred into the oviducts of pseudopregnant Sprague-Dawley rats. Thus, the conclusions reached at this time are relevant only to men and therefore half the overall population and far less of the clinically relevant population. Arousal changes the general state of rats. Yet, all of the experiments are conducted on male rats. I completely agree with this article. These data suggest that astrocyte activation does not affect new memory formation. Consistent with the results in male rats, the photostimulated female rats showed no difference in freezing levels during fear conditioning compared with controls (sham operation) (Figure 2—figure supplement 1B). Ca2+ signals were calculated as the relative change in fluorescence (ΔF/F), where F is the fluorescence intensity before photostimulation and ΔF is the change in fluorescence after photostimulation. These data are summarized in Figure 1—figure supplement 1 in the revised manuscript. (C) Freezing levels tested on day 2 of control and photostimulated rats (p = 0.6548, Student’s unpaired two-tailed t-test). Researchers say one new case of dementia is detected every four seconds globally. I was always in pain and tired, moreover, I couldn’t remember a thing. Overall, the study is very well-designed and thorough. When a man reaches about age 25, his prostate begins to grow. In the control group, we microinjected tdTomato instead of hPMCA2w/b (Figure 2—figure supplement 4A and B). Although the primate visual system has been extensively studied, detailed spatial organization of white matter fiber tracts carrying visual information between areas has not been fully established. If that seems daunting, start with a few minutes a day, and increase the amount you exercise by five or 10 minutes every week until you reach your goal. so, a person should regular do exercise for their health. Indirectly, exercise improves mood and sleep, and reduces stress and anxiety. You can also bring down the severity and frequency of that back pain you have been complaining of. Data are presented as the mean ± SEM. The neurons were plated on a layer of astrocytes and maintained at 37°C in a 5% CO2 incubator.

This is vary halpful, well written article I would like to post the link to this article on 4) Only hippocampus is stimulated. Some description has been added into the Introduction in the revised manuscript. Aquaparki – it’s a huge number of cases, a set of multiple pools both indoor and outdoor applications. Stress lives in the hippocampus region of the human brain which is also responsible for motivation, emotion and memory, study shows. Please let us know if you would like to pursue this option. Try any or all of these ideas: Whatever exercise and motivators you choose, commit to establishing exercise as a habit, almost like taking a prescription medication. All statistics were calculated with GraphPad Prism (Version 6.01). Reliance on any information provided is solely at your own risk. b) The adenosine A1 receptor (A1R) is a G-protein-coupled receptor (GPCR) that preferentially couples to inhibitory Gi/o heterotrimeric G proteins. We know that exercise has great benefits for our heart but, we rarely think about the benefits for the human brain. Astrocyte Ca2+ signaling was attenuated by the expression of the Ca2+-extruder PMCA2w/b (plasma membrane Ca2+ ATPase isoform 2 splice variant w/b) in hippocampal astrocytes (Yu et al., 2020; Yu et al., 2018). All surgery was performed under sodium pentobarbital anesthesia, and every effort was made to minimize suffering. This work provides essential information for interpretation of functional and diffusion-weighted MRI data, as well as revision of wiring diagrams based upon observations in the vervet visual system. The slice was visualized under a microscope (BX51WI, Olympus, Japan) using infrared differential interference contrast optics. https://doi.org/10.1146/annurev.psych.55.090902.142050, Purinergic signalling in neuron-glia interactions, Optogenetic experimentation on astrocytes, https://doi.org/10.1113/expphysiol.2010.052597, Astrocytic β2-adrenergic receptors mediate hippocampal long-term memory consolidation, Astrocytes control breathing through pH-Dependent release of ATP, Novelty causes time-dependent retrograde amnesia for one-trial avoidance in rats through NMDA receptor- and CaMKII-dependent mechanisms in the Hippocampus, https://doi.org/10.1046/j.1460-9568.1999.00742.x, https://doi.org/10.1152/physrev.00018.2015, Continuing the search for the Engram: examining the mechanism of fear memories, Memory allocation: mechanisms and function, https://doi.org/10.1146/annurev-neuro-080317-061956, The molecular and systems biology of memory, https://doi.org/10.1016/j.cell.2014.03.001, Lifetime prevalence and age-of-onset distributions of DSM-IV disorders in the national comorbidity survey replication, https://doi.org/10.1001/archpsyc.62.6.593, Modality-specific retrograde amnesia of fear, Long-term plasticity of hippocampal interneurons during in vivo memory processes, https://doi.org/10.1016/j.conb.2018.08.006, A critical Time-Window for the selective induction of hippocampal memory consolidation by a brief episode of Slow-Wave sleep, https://doi.org/10.1007/s12264-018-0303-x, Neurobiology of pavlovian fear conditioning, https://doi.org/10.1146/annurev.neuro.24.1.897, Seeking a spotless mind: extinction, deconsolidation, and erasure of fear memory, https://doi.org/10.1016/j.neuron.2011.04.023, The contextual brain: implications for fear conditioning, extinction and psychopathology, Synapse-specific astrocyte gating of amygdala-related behavior, Astrocytes detect and upregulate transmission at inhibitory synapses of somatostatin interneurons onto pyramidal cells, https://doi.org/10.1038/s41467-018-06731-y. It has been demonstrated that ChR2 expression is nontoxic, safe, stable, and functional (Aravanis et al., 2007; Cardin et al., 2010; Deisseroth, 2011; Doroudchi et al., 2011; Zhang et al., 2006). Some descriptions have been added to the Results section in the revised manuscript. They were shown to have contextual fear memory which still has 30-40% freezing at D26 (Figure 3E). We agree with the reviewer that adenosine lowers arousal. Don’t forget that household activities can count as well, such as intense floor mopping, raking leaves, or anything that gets your heart pumping so much that you break out in a light sweat. Problems in these areas frequently cause or contribute to cognitive impairment. Interestingly, contextual fear memory but not cued fear memory (Figure 2J and K) was significantly increased in hPMCA2w/b rats.

The Content is not intended to substitute for professional medical advice, diagnosis, or treatment. Maybe you want to lose weight, lower your blood pressure, prevent depression, or just look better. Here we used 3D polarization light imaging (3D-PLI), which enables direct visualization of fiber tracts at micrometer resolution, to identify and visualize fiber tracts of the visual system, such as stratum sagittale, inferior longitudinal fascicle, vertical occipital fascicle, tapetum and dorsal occipital bundle in vervet monkey brains. That’s what the most common form of investment in the market sports – recreational. Back pain can occur because of an imbalance between the strength of the abdomen and back muscles. I can attest to this having been told I was experiencing menopausal symptoms. This is mainly due to the large gap between tracer studies and diffusion-weighted MRI studies, which focus on specific axonal connections and macroscale organization of fiber tracts, respectively. ATP-γ-S and MesADP induce a [Ca2+]i increase in many types of neurons and glia. Both articles and products will be searched. (B) Freezing levels of control (sham operation, n = 7) and photostimulated GFAP-ChR2-EYFP rats (n = 8) during fear conditioning. In addition, we followed the reviewer's suggestion by performing IHC experiments and confirmed the specific expression of ChR2 in different brain areas such as the motor cortex, lateral posterior thalamic nucleus, and dorsomedial hypothalamic nucleus. However, there are some concerns. The term hippocampus is derived from the Greek word hippokampus (hippo meaning "horse" and kampos meaning "sea monster") because the structure resembles the shape of a sea horse. Even in the hippocampus, the newly born neurons in the dentate gyrus may also transit through a period of GFAP positivity. These points should be discussed intensively. Furthermore, in the test phase of OLR on day 28, the conditioned rats spent more time exploring the object in a novel location relative to the object in a familiar location (Figure 3I) and the discrimination index was similar to controls (Figure 3J). The Pavlovian fear conditioning paradigm is a commonly-used animal model of PTSD (Mahan and Ressler, 2012). Exercise is becoming a therapy for those afflicted by this condition. Thank you for submitting your article "Activation of astrocytes in hippocampus decreases fear memory through adenosine A1 receptors" for consideration by eLife. Also, that arousal affects performance in learning tests. Instead of fear retraining, another form of hippocampus-dependent memory test might be more relevant to draw the conclusion of "astrocyte activation does not affect new learning". At present, ChR2 is widely used to explore the role of glia in regulating rodent behavior and circuits by precisely manipulating their Ca2+ signaling (Bang et al., 2016; Figueiredo et al., 2011; Gourine et al., 2010; Nam et al., 2016; Perea et al., 2014; Yamashita et al., 2014). We have addressed this issue in the Results section in the revised manuscript. Very useful article. So what should you do? I really like these articles , they are very useful. Recordings were made with an Axon 700B patch-clamp amplifier and 1320A interface (Axon Instruments, USA). It has been proposed that long-term potentiation (LTP), a form of synaptic plasticity, is an intrinsic property of this consolidation (Abraham and Williams, 2008; Kandel et al., 2014). The funders had no role in study design, data collection and interpretation, or the decision to submit the work for publication. At the current standard is the presence of water attractions, hi it’s a fentastics prose might become benificiary for me can change my life style. Hot baths and saunas: Beneficial for your heart? Following the reviewer’s suggestion, we repeated the experiments in which the rats receiving photostimulation immediately after fear acquisition showed a persistent decrease of contextual fear memory lasting up to 26 days (Figure 3D and E). As expected, we found that blocking either GAT1 or GAT3 prolonged oscillations. 8) Figure 3D-G, why did the rats with retraining at D27 have very low freezing baseline? We thank the reviewer for raising this important concern. The culture medium was changed every 2–3 days. Never disregard professional medical advice or delay in seeking it because of something you have read in a public group(s). Your article has been reviewed by three peer reviewers including Margaret M McCarthy as the Reviewing Editor and Reviewer #1, and the evaluation has been overseen by Laura Colgin as the Senior … 5 Internet recommendations for joint pain: Do they work? Receptor activity that is either too brief or too protracted fails to sufficiently open T-type channels necessary for sustaining oscillations. How these mutations alter the structure and function of individual synapses on direct and indirect pathway SPNs is unknown and may reveal pre-clinical changes in dopamine-recipient neurons that predispose towards disease. Seahorse (also written sea-horse and sea horse) is the name given to 46 species of small marine fish in the genus Hippocampus. However, our major conclusion of photostimulation- and drug-induced fear memory attenuation is supported by evidence including: (a) we delivered the photostimulation and drugs after but not before or during the Pavlovian fear conditioning. Having a head and neck suggestive of a horse, … The author should discuss (based on A1R pharmacokinetics) how this slight increase in interstitial adenosine could have such a profound effect on the molecular and synaptic underpinnings of memory. . The authors generated GFAP-ChR2-EYFP rats to enable optogenetic manipulation of astrocytes in rats. In addition, characterization of ChR2 expression in different brain areas other than hippocampus will be informative, considering the recent concern of GFAP as astrocyte specific promoter. b) Specific ChR2 expression induces Ca2+ elevation in astrocytes and has been used as a tool for astrocyte activation (Chen et al., 2013; Figueiredo et al., 2011; Gourine et al., 2010; Tan et al., 2017). Adenosine increased by optogenetic stimulation will necessarily have the same effect as drug administration to alter adenosine levels. It is likely that the potential effect of astrocyte Ca2+ activity with local ATP-γ-S or MesADP infusion on fear memory was obscured by their effects on neurons. And the real extracellular adenosine concentration is higher than that in the dialysate because adenosine is metabolized extremely fast, and in the process of sample collection, the material in the probe and tubing, flow rate, probe length, and recovery can influence the quantitative estimation of extracellular fluid concentrations (Hammarlund-Udenaes, 2017).
