Although our data do not determine whether these regions play a causal role in the formation of political attitudes, they converge with previous work [4, 6] to suggest a possible link between brain structure and psychological mechanisms that mediate political attitudes.

Summary==>
"Substantial differences exist in the cognitive styles of liberals and conservatives on psychological measures [1]. Variability in political attitudes reflects genetic influences and their interaction with environmental factors [2 and 3]. Recent work has shown a correlation between liberalism and conflict-related activity measured by event-related potentials originating in the anterior cingulate cortex [4]. Here we show that this functional correlate of political attitudes has a counterpart in brain structure. In a large sample of young adults, we related self-reported political attitudes to gray matter volume using structural MRI. We found that greater liberalism was associated with increased gray matter volume in the anterior cingulate cortex, whereas greater conservatism was associated with increased volume of the right amygdala. These results were replicated in an independent sample of additional participants. Our findings extend previous observations that political attitudes reflect differences in self-regulatory conflict monitoring [4] and recognition of emotional faces [5] by showing that such attitudes are reflected in human brain structure. Although our data do not determine whether these regions play a causal role in the formation of political attitudes, they converge with previous work [4 and 6] to suggest a possible link between brain structure and psychological mechanisms that mediate political attitudes."

"Our findings show that high-level concepts of political attitudes are reflected in the structure of focal regions of the human brain. Brain structure can exhibit systematic relationships with an individual's experiences and skills [19 and 20], can change after extensive training [21 and 22], and is related to different aspects of conscious perception [23 and 24] (see [25] for a review). We now show that such relationships with brain structure extend to complex aspects of human behavior such as political attitudes. This opens a new avenue of research to map high-level psychological features onto brain structure and to interpret sociologically motivated constructs in terms of brain functions."
