Neurogenesis: The Complex Nature Of The Brain

Neurogenesis is the process in which new neural stem cells are created. In the past, it was thought that this process ends in childhood. New studies have proven this wrong, and in fact neurogenesis continues to occur throughout adulthood. It is now hypothesized to play to be the main component in neural plasticity, our ability to learn, and memorize. There are many factors that can affect neurogenesis, both genetic and environmental. Cruz and Nixon (2003) sought to see what effects, if any, that alcohol has on adult neurogenesis. They also address what other factors play a role in alcohol consumption, and how they play a role in neurogenesis. The article, as well as other psychological research, continue to show the complex nature of the brain, and the many cause and effect relationships that lie within. …show more content…
The SVZ is where the neurons of the olfactory bulb are made, and the hippocampus has been linked to learning and memory, making it the prime place for neural plasticity (Anderson, 2015). The hippocampus also seems to be the supplier of NSCs for the rest of the brain. This gives the brain the ability to heal damage, develop new connections, and strengthen old ones. The question then is, what does alcohol do to these functions (Crews et al.,
