Momento is a movie about a man, Leonard Shelby, with anterograde amnesia, severe loss of the ability to form new episodic and semantic memories. These memories are formed and retained in the hippocampus and when there is an injury to this part of your brain it can cause short-term memory loss. Leonard sustained short-term memory loss when he was hit over the head and knocked out after witnessing the rape and murder of his wife. Throughout the remainder of the movie we see snippets of actual…

4.1 Introduction: Stress is one of the most prevalent and life-threatening forms of mental illness affecting more than one fifth of the world’s population. It is always related to alterations of signaling pathways mainly the hypothalamic-pituitary-adrenal axis (Mikhai et al, 2014). Rat models are an obligatory tool to study the etiology and progression of behavioural and biochemical changes induced by oxidative stress. Restraint stress produces an imbalance between oxidants and antioxidants…

The spread of the performing arts, children, teens, and adults in the 21st century have gained an interest in learning how to play musical instruments. Studies have shown that people who not only listen to music, but play a musical instrument themselves, use more parts of the brain. Not only can it prevent them for getting a disease that affects their ability to think, but it also causes people to learn at rapid speed. “The human brain is one of the most complex organs in the human body. It…

Nurture is defined as the collective impact of all environmental factors that affect growth and behavior. Because it is very difficult to control the differences in the environments of people with severe anxiety, determining the main factor is problematic. Many psychologists believe that anxiety is a product of childhood experiences. If a child is raised in a harmful environment, it will reflect on his or her behavior during adolescence and adult life. This is not only believed for diseases,…

Drug addiction is a powerful condition that imprisons the mind and body of its users, which leads to the question of whether the option to use remains a choice or becomes a disease. Current statistics reveal that 24.6 million Americans reported using illicit drugs in 2013 (SAMHSA, 2014). That number alone is clear evidence of a significant drug problem in our society. Throughout history there have been conflicting opinions about drug addiction being a choice or a disease. In this paper, I will…

(Cardino 1999). The part of the brain that seems to be touched by schizophrenia is the hippocampus. This part of the brain is called the limbic system which is responsible for processing emotions and memories. The hippocampus is smaller in those with schizophrenia (Geddes, Xu-Feng, Newell 2014). In one study, even in children as young as 12, the difference in hippocampus size was seen. Moreover, the hippocampus continued to shrink in the 12 years of follow-up in the study (Geddes, Xu-Feng,…

Alzheimer's is a progressive disease. When does it begin? And why does it cause forgetfulness? Alzheimer’s is a disease, which causes memory loss, and it causes difficulty dealing with daily life (1). Alzheimer’s disease happens because damage of cells in certain regions of the brain and these areas relate memory (2). Over time, all brain cells will die. As a result, it will cause for Alzheimer’s patient difficulty dealing with daily life (2). It has three stages which are mild Alzheimer's…

between HPC-PFC, functional studies in rodents have shown that both these substrates interact among each other with synchronized neuronal activity 1,37,38. Especially, there is an increase in theta frequency synchronization between the ventral hippocampus and the medial PFC in mice exposed to an anxiogenic environment, implicating this circuit in behavioral inhibition, characterized by reduced exploration during anxiety 39. Conversely, impaired synaptic plasticity of this circuit is reported in…

Depending on the family or area a person grows up in, everyone is given different opportunities. Someone who conceives a child at sixteen might not be able to provide that child with as much support as someone who is older and has a steady job. Also, children who grow up in homes with parents who are alcoholics or drug users, might fall in that same path and have less opportunity than those who have good role models as parents. Parents who drink or smoke while pregnant put their children at…
