... parts of the brain, the dentate gyrus (Gage et al., 1995) [2] and the subreventicula zone of the adult brain (Reynolds and Weiss, 1992; Richards et al., 1992). [2]They showed that we no longer^ had to consider that a complex neuron was required to divide for^ adult neurogenesis to occur. Now we know that these neurons can^ be generated from primitive cells, similar to what happens in^ development. Firstly, the dentate gyrus of the hippocampus, which is the part of the brain associated with our learning and memory. The second part of the brain is the subreventicular zone of the anterior lateral ventricles and its projection through the rostral migratory stream to the olfactory bulb that allows the new neuron to generate within the brain. The discovery of neural stem cells (NSC) and adult neurogenesis provides a new theoretical framework for understanding processes regulating brain plasticity (Gage 2000)[3] which are ...
