The social brain meets neuroimaging
RIM Dunbar - Trends in cognitive sciences, 2012 - cell.com
Recent neuroimaging studies in humans have indicated that individual differences in social
network size correlate with amygdala volume and the volume of brain regions associated …

Intrinsic amygdala–cortical functional connectivity predicts social network size in humans
Using resting-state functional magnetic resonance imaging data from two independent
samples of healthy adults, we parsed the amygdala's intrinsic connectivity into three partially …

Social network size affects neural circuits in macaques
It has been suggested that variation in brain structure correlates with the sizes of individuals'
social networks. Whether variation in social network size causes variation in brain structure …

The amygdala: is it an essential component of the neural network for social cognition?
Observations from human subjects with focal brain lesions and animal subjects with
experimental lesions have implicated a variety of brain regions in the mediation of social …

Shared neural coding for social hierarchy and reward value in primate amygdala
The social brain hypothesis posits that dedicated neural systems process social information.
In support of this, neurophysiological data have shown that some brain regions are …

Social brain volume is associated with in-degree social network size among older adults
The social brain hypothesis proposes that large neocortex size evolved to support
cognitively demanding social interactions. Accordingly, previous studies have observed that …
