New in Cerebral Cortex

Much work on approach-avoidance conflict has used experimental paradigms that involve spatial/contextual information. Here, using fMRI and neurologically healthy participants, we examined the neural correlates associated with an object-based approach-avoidance task and found that the resolution of object-based approach-avoidance conflict was associated with predominant perirhinal cortex, rather than anterior hippocampus, activity. Our findings suggest that medial temporal lobe structure involvement in approach-avoidance conflict may be influenced by the type of stimuli involved.
