While expressions of sympathy are predicted by the same factors as fear, expressions of solidarity, evidenced by the use of the defiant #bostonstrong hashtag, reveal interesting dynamics in which fear itself appears to play an important role.
Recent neuroimaging and neurophysiological studies have proposed that processing fear expressions is related to increased neural activity in areas involved in attentional networks[8], such that fearful faces enhance visual responses in the extrastriate occipital cortex[9].
Neither amygdala damage nor epileptic condition affected the responses to the morphed fear expressions (all P > 0.1).
Mixed ANOVA was used to analyze participants' responses to the morphed stimuli that included some degree of fear expressions (see Fig. 1).
The right IP "agency" areas that were discussed in the previous section are coincidentally adjacent to a region of IP cortex that when damaged, results in a deficit in the recognition of facial fear expressions.
