Professor of Psychology

Description

Professor Liz Gould started her talk by sharing some history on the central belief that adults do not make new neurons. This view was accepted as doctrine until relatively recently. Scientists claimed evidence for mammalian neurogenesis in the 70s and 80s, but they were not believed. A scientific revolution occurred in the 90s with multiple labs reporting on adult neurogenesis. In 1990 there were zero papers on this topic, but by 2010 an astounding 500 papers were published supporting adult neurogenesis. Using new techniques for labeling and optical confocal microscopy, scientists can now see direct evidence for neurogenesis in the hippocampus of adult rats. Research using the rat model has shown that stress elevates glucocorticoid levels and this decreases neurogenesis. Rewarding experiences, on the other hand, enhance creation of neurons. At this point in the research there is evidence for adult neurogenesis in mice, rats and some old and new world primates and some preliminary results in humans.
