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 effects through their impact on the nucleus accumbens or other structures

Psychopath‚ sociopath‚ psycho‚ and crazy are terms used by the public for years. They are commonly used interchangeably with little understanding of what they mean.

certain why this happens‚ but genetics can play a part in the onset. The decreased size of the cerebral volume causes the brain to function differently as well. For example‚ children with BSD also have a hyperactive amygdala and a hypoactive prefrontal cortex (Weis‚ 2014). The amygdala is responsible for the brain’s “fight or flight” reflex and since it is more sensitive than normal‚ this can cause problems like developing phobias or acting out repeatedly. The prefrontal cortex‚ which is in charge

done by Ross‚ et al. (1994) showed that PTSD sufferers do not achieve proper REM sleep. REM sleep is crucial for memory consolidation; however‚ it is also the time in which the amygdala is most active (BBC‚ 2009). The amygdala is a structure in the brain responsible for emotions such as fear‚ in PTSD sufferers‚ the amygdala is more active as opposed to those who do not have the disorder (Shin‚ et. al.‚ 2006).

who are always interested in what is in it for themselves‚ the ones that cannot maintain steady relationships with others. The part of the brain that aids in producing and expressing emotions is the amygdala. The amygdala is connected to the autonomic fear response as well. In psychopaths‚ the amygdala is shown to not be as active as it should be. This defect causes an infinity for risk taking and spontaneity‚ making psychopaths fairly dangerous. One could argue that the only aspect of humans that
