The orexigenic hormone acyl-ghrelin increases adult hippocampal neurogenesis and enhances pattern separation
An important link exists between intact metabolic processes and normal cognitive functioning; however, the underlying mechanisms remain unknown. There is accumulating evidence that the gut hormone ghrelin, an orexigenic peptide that is elevated during calorie restriction (CR) and known primarily for stimulating growth hormone release, has important extra-hypothalamic functions, such as enhancin...
متن کاملAdult Hippocampal Neurogenesis and Memory
Adult neurogenesis, a concept emergent in the late 1990s, is the generation of new neurons in the adult brain. This process occurs thank to cells who have this proliferative feature, named as Neural Stem Cells (NSCs). Neural Stem Cells (NSCs) are primary progenitors who can generate the two neural types (neurons and glia). Classically it was assumed that NSCs are only present in the embryo, but...

متن کاملD-serine increases adult hippocampal neurogenesis
Adult hippocampal neurogenesis results in the continuous formation of new neurons and is a process of brain plasticity involved in learning and memory. The neurogenic niche regulates the stem cell proliferation and the differentiation and survival of new neurons and a major contributor to the neurogenic niche are astrocytes. Among the molecules secreted by astrocytes, D-serine is an important g...
متن کاملThyroid hormone regulates hippocampal neurogenesis in the adult rat brain.
We have examined the influence of thyroid hormone on adult hippocampal neurogenesis, which encompasses the proliferation, survival and differentiation of dentate granule cell progenitors. Using bromodeoxyuridine (BrdU), we demonstrate that adult-onset hypothyroidism significantly decreases hippocampal neurogenesis. This decline is predominantly the consequence of a significant decrease in the s...
