A twin study of intracerebral volumetric relationships.

abstract：:Recent studies have identified genes that influence the length of the circadian period maintained by mice housed under constant lighting conditions. However, a less studied circadian activity variable is the amplitude of daily oscillations in locomotor activity. This parameter reflects spontaneous activity exhibited u...

Recent research indicates that nonadditive genetic effects, such as dominance and epistasis, play a large role in personality variation. One possible explanation for the latter finding is that there has been recent selection on human personality. To test this ...
