The BOLD signal in the amygdala does not differentiate between dynamic facial expressions

Christiaan van der Gaag, Ruud B. Minderaa, Christian Keysers
2007 Social Cognitive and Affective Neuroscience  
The amygdala has been considered to be essential for recognizing fear in other people's facial expressions. Recent studies shed doubt on this interpretation.  ...  The amygdala was found to respond more to movies of facial expressions than to pattern motion, but no differences were found between the responses to neutral, happy, disgusted and fearful facial expressions  ...  In this view the amygdala thus contributes to the processing of facial expressions not directly by detecting the expressed emotion, but indirectly, by directing the processing of facial expressions towards  ...

Emotion and Cognition: Insights from Studies of the Human Amygdala

Elizabeth A. Phelps
