Hippocampus

 Hippocampus, which is known to encode a new protein called PGC-1α that acts as a strong synaptic activator in the hippocampus.  The fact of course remains there are many factors involved with stress and cognitive dysfunction including loss or disease of brain cells - but since we know this can happen more frequently then you might think people would assume it's related to the illness so doctors look for clues if they get an old wound on their scalp from being spanked/tossed around all day long? 

Hippocampus in humans and other primates is associated with anxiety-like behavior. In addition to the hippocampal dysfunction that may be involved here, we are interested herein also in how impaired brain function relates directly or indirectly using a novel model of neurodegenerative diseases. We observed previously in Alzheimer's disease patients reduced cognitive performance on measures of attention span across two tests—the spatial working memory task and an executive function test based upon time spent searching for objects within stimuli rather than trying multiple targets simultaneously over short periods of time.
