Adult Hippocampal Neurogenesis in Different Taxonomic Groups: Possible Functional Similarities and Striking Controversies

Adult 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...

O18: Role of Adult Hippocampal Neurogenesis in Anxiety Disorders

Neurogenesis occurs throughout life in several regions of the brain. In this lecture, a new sight for the role of the dentate gyrus and adult hippocampal neurogenesis in anxiety disorders will be discussed. The region that has obtained the most attention for its involvement in the neurogenesis of affective and anxiety disorders are the hippocampal and dentate gyrus. Evidence strongly suggests t...

Why new neurons? Possible functions for adult hippocampal neurogenesis.

The dentate gyrus of the adult hippocampal formation generates neurons throughout life. To date, it remains unclear why. What are the new neurons used for? How can an existing functional neural network integrate and even actively recruit new neurons? The prevailing theories of cognition are based on the assumption that the adult brain is a stable network with regard to the number of neurons. In...
