was in his mid-forties he was infected by a viral infection encephalitis. It caused brain damage in the hippocampus and after that he was affected with anterograde and retrograde amnesia. His memory lasted from 07-30 seconds and he was unable to create new memories. He could not transfer information from short-term memory to long-term memory. An MRI scan showed that Wearing’s brain’s hippocampus and some of the frontal regions has been damaged because of the viral infection. But he could still conduct

Using PET scans‚ researchers can show that early stages of Alzheimer’s disease has a reduction in brain metabolism in hippocampus. Masconi(2005) have developed brain-scan-based computer and found out that in the early stages of Alzheimer’s disease there is a reduction in brain metabolism in the hippocampus. He also found out that early signs of reduced metabolism in hippocampus was associated with later development of Alzheimer disease. Therefore‚ PET scan is useful in finding out the early development

The hippocampus is the part of the brain that is responsible for converting information from short-term memory to long-term memory. When a person is experiencing stress‚ a hormone known as cortisol is released is known to have an affect on the hippocampus. The over exposure to this hormone can cause irreparable damage to the hippocampus. Over exposure in the early childhood years can lead to permanent mental health problems

alterations of neuroplasticity in certain brain regions produce a pro-depressive effect. Some studies suggest that neuroplasticity in the mesolimbic dopamine circuit can produce effects that are opposite to the antidepressant effects observed in the hippocampus. Although circumstantial‚ there is evidence that neuroplasticity in the amygdala may work contrary to antidepressant effects. There is a concern that novel therapeutic strategies aimed at enhancement of neuroplasticity may have unintended pro-depressant
