Neural systems supporting interoceptive awareness
TLDR
In right anterior insular/opercular cortex, neural activity predicted subjects' accuracy in the heartbeat detection task and local gray matter volume correlated with both interoceptive accuracy and subjective ratings of visceral awareness.
Conscious and unconscious emotional learning in the human amygdala
TLDR
The results indicate that the human amygdala can discriminate between stimuli solely on the basis of their acquired behavioural significance, and second, this response is lateralized according to the subjects' level of awareness of the stimuli.
Phobias and preparedness: the selective, automatic, and encapsulated nature of fear
TLDR
Evidence is described for an evolved module for fear elicitation and fear learning that is preferentially activated by stimuli related to survival threats in evolutionary history, and there are two levels of fear conditioning, with an emotional level that is relatively independent of the cognitive contingency level.
Genetic Gating of Human Fear Learning and Extinction
TLDR
Results show that only carrier of the 5-HTTLPR s allele exhibited conditioned startle potentiation, whereas carriers of the COMT met/met genotype failed to extinguish conditioned fear.

Behavioral data suggest that fear stimuli automatically activate fear and capture attention. This effect is likely to be mediated by a subcortical brain network centered on the amygdala. Consistent
