Finally, they explain that the neural system that holds dorsal striatum can convey the formation of “reinforced stimulus-response associations” (McDonald, White, 2013). Simply put, because of the relationship between neutral stimuli and responses being ‘reinforced,’ the dorsal striatum is seen as an adjunctive learning system (McDonald, White, 2013). In their article they explained in detail the importance of these three regions of the brain through experiments with three hundred twelve (312) male Long-Evans rats. After 4 experiments with the rats the researchers mentioned in McDonald and White’s article, learn that there are indeed multiple memory systems within the mammalian nerve system. Each of these systems work together to help mammalians learn multiple things simultaneously. This knowledge proves that we, as mammalian human beings, are able to learn a deeper understanding in our studies and make better decisions through memory (McDonald, White, …show more content…
But after nearly 30 years of research, scientist have conniving proof that adult mammalian including human adults, have a continuous growing amount of neurogenesis. The importance of adult neurogenesis is how it effects our memory formation in the hippocampus. In the learning area, neurogenesis increases through studying and learning, while it decreases from sleep deprivation and drug abuse (Ayumu et. al, 2013). “It might be reasonable to conclude that when the brain is in good states, both adult neurogenesis and learning ability are high. When the brain is in bad states, both are low (Ayumu et. al, 2013, p.#). Environment and stress can affect growth and decrease of neurogenesis as well as our own mindset of how learning works. “A stability Bias in Human Memory,” by phycologist Nate Kornell and Robert A. Bjork says “Stability bias in human memory that is, a failure to appreciate the degree to which memory can change over time” (Kornell, Bjork, 2013). “These findings highlight the difference between holding a belief (i.e., that forgetting happens) and putting that belief into practice (i.e., behaving as if forgetting happens) (Kornell, Bjork, 2013). As we age, forgetting will happen over time, yet studying will give growth in
