The hippocampus is subdivided into several distinct zones: the dentate gyrus (DG), CA3, ... at least in part, by increasing the expression of brain-derived neurotrophic factor (BDNF) and neurogenesis in the hippocampal and cortical circuits. International Scientific Journal & Country Ranking. Scientists are unsure whether the small size is the result of depression or if it is a contributing factor. Basic feedback mechanisms in the hippocampus that help modulate the release of glucocorticoids during stress may be compromised, compounding the effects of chronic stress by leading to chronically elevated cortisol levels. The hippocampus is a vulnerable and yet resilient brain region, and excitatory amino acids play an important role in normal plasticity as well as in damage produced by ischemia, seizures and head trauma. Research over the last 5 years has firmly established that learning and memory abilities, as well as mood, can be influenced by diet, although the mechanisms by which diet modulates mental health are not well understood. In addition, two behavioral interventions, wheel running (WR) and environmental complexity (EC), were utilized as rehabilitative therapies for alcohol-induced deficits. Neurons and Cognition [q-bio.NC]. 6.3. Le Brain-derived Neurotrophic Factor (BDNF) est impliqué dans les processus cognitifs impliquant l'hippocampe et les structures corticales. However, the long-term consequences of an infection with neurotropic and non-neurotropic influenza A virus (IAV) variants for the CNS remain elusive. Impact of video games on plasticity of the hippocampus GL West1, K Konishi2, M Diarra1, ... is because lower grey matter in the hippocampus is a risk factor for developing numerous neuropsychiatric illnesses.13–15 We posit that the ideal is a balanced use of both the hippocampus and caudate nucleus memory systems. In addition, we … Crossref. Here, we show that loss of IR/IGF1R in the hippocampus and central amygdala of adult mice results in decrease in glutamate receptors, accompanied by glucose intolerance, anxiety-like behavior, and impaired cognition. Impact Factor: 2.274 ℹ Impact Factor: 2019: 2.274 The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. Therefore, we investigated the role of exercise and thiamine supplementation on spatial memory and on brain-derived neurotrophic factor (BDNF) and acetylcholine (Ach) content in the hippocampus of the stressed animals. HIPPOCAMPUS: People and other animals experiencing isolation may have smaller-than-normal hippocampi and reduced concentrations of brain-derived neurotrophic factor (BDNF), both features associated with impaired learning and memory. However, less is known about the impact of brain insulin and IGF-1 receptor (IR/IGF1R) loss in adult mice, especially in higher neural processing regions. Frontiers in Cell and Developmental Biology is a broad-scope, interdisciplinary open-access journal, focusing on the fundamental processes of life, led by Prof Amanda Fisher and supported by a geographically diverse, high-quality editorial board. Compared with the DMSO group, there were increased expression of microglia identification marker Iba1 and more Iba1 positive cells in CA1 and DG with the swollen soma and retracted processes in 5 μg dose of SU5402 group. Some studies indicate that levels of the stress hormone cortisol, which affects and is regulated by the hippocampus, are higher in isolated animals. , p. 7. The hippocampus shrinks in late adulthood, leading to impaired memory and increased risk for dementia. Google Scholar. One of the brain structures associated with learning and memory, as well as mood, is the hippocampus. ISSN: 0953-816X. The hippocampus is another very important structure in the limbic ... highlighting the seriousness of chronic stress and its physiological impact. The best-studied growth factor is brain derived neurotrophic factor (BDNF), highly concentrated in the hippocampus (Wetmore et al., 1990; Murer et al., 2001). Posted Nov 25, 2018 72 (8): 655 – 662. Search ADS. … Université de Strasbourg, 2013. Even normal aging is associated with a gradual decline in some types of memory, including episodic memory and working memory (or short-term memory). Stress also has important effects on the hippocampus via adrenal steroids and excitatory amino acids. 97, Issue. The noise pollution accompanying industrialization is a risk factor to human health. Biol Psychiatry. In the hippocampus of MS rats there was a significant decrease in brain-derived neurotrophic factor and synaptophysin mRNA densities.
