Conscious and unconscious emotional learning in the human amygdala
Article Abstract:
Human subjects are shown an angry face for under 40 milliseconds and then shown an expressionles mask directly afterwards. Subjects only report seeing the mask, rather than the angry face or target. Volunteers were shown two angry faces and one of these was associated with white noise as a result of previous conditioning. A neural response occurred in the right amygdala when the conditioned face was shown in masked presentations, while if the same face was shown unmasked, the left amygdala showed enhanced activity. Levels of awareness are reflected in which amygdala is involved.

Staring fear in the face
Article Abstract:
A common view exists that the perception of fear might guide appropriate visuomotor behaviour. The author here describes a patient (SM) who has bilateral brain lesions in the amygdala, a region of the medical temporal lobe known to be critical for the perception of fear.
