Given the extensive interconnections between the amygdala and orbitofrontal regions one might also expect to see alterations in the ventral frontal regions as well.

Increased amygdala and insula activation during emotion processing in anxiety-prone subjects. In addition to these behavioral differences, preterm children exhibited lower regional brain volumes in the cortex, ventricles, basal ganglia, amygdala, hippocampus, and corpus callosum. In addition, it provides very clear anatomical and functional accounts of the orbitofrontal cortex, the amygdala, and the peripheral nervous system. Event-related activation in the amygdala associates with later memory for individual emotional experience. As predicted, there was significant attenuation of affective load-response by patients with mania in the anterior cingulate cortex and amygdala. Quenching inhibition of development and expression of amygdala kindled seizures with low frequency stimulation. This factor appears to have a basis in subcortical limbic function, particularly the medial temporal lobe structures, the amygdala, and hippocampus. Magnetic resonance imaging volumes of the hippocampus and the amygdala in women with borderline personality disorder and early traumatization. In comparison to normal controls, a subject with bilateral amygdala damage had difficulty identifying emotions (happy, angry, sad) in sentences that were read to her.
