Anterior cingulate cortex
It appears to play a role in a wide variety of autonomic functions, such as regulating blood pressure and heart rate.
Periamygdaloid cortex
The periamygdaloid cortex is part of the primary olfactory cortex which receives input from the olfactory bulbs via the lateral olfactory tract. Along with the amygdala, the periamygdaloid cortex conducts cognitive evaluation of the olfactory input it receives and projects it back to the olfactory bulbs.
