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

Villeda et al. also designed a fear conditioning experiment to test the involvement of the amygdala; in contrast‚ in this test‚ the mice learned to associate a shock with a visual and audio cue. However‚ the results from this task indicated that heterochronic parabionts did not perform better on these tests. This verified that young blood resulted

Williams syndrome also recognized as Williams-Beuren syndrome is a genetic disorder caused by a deletion of more than twenty five genes from chromosome 7. Although Williams syndrome is often non-hereditary‚ the chances of the syndrome being passed on if an individual with Williams syndrome has a child are fifty percent.
