This study, using fMRI in conjunction with masked stimulus presentations, represents an initial step toward determining the role of the amygdala in nonconscious processing.
The amygdala: vigilance and emotion
A review of available studies examining the human amygdala covers both lesion and electrical stimulation studies as well as the most recent functional neuroimaging studies, and attempts to integrate basic information on normal amygdala function with the current understanding of psychiatric disorders, including pathological anxiety.

A functional magnetic resonance imaging study of amygdala and medial prefrontal cortex responses to overtly presented fearful faces in posttraumatic stress disorder.
These results provide evidence for exaggerated amygdala responsivity, diminished medial prefrontal cortexresponsivity, and a reciprocal relationship between these 2 regions during passive viewing of overtly presented affective stimuli unrelated to trauma in PTSD.

Human Amygdala Responsivity to Masked Fearful Eye Whites
The amygdala was more responsive to fearful (larger) eye whites than to happy (smaller) eye whites presented in a masking paradigm that mitigated subjects' awareness of their presence and aberrant…
