Emotional valence modulates activity in the posterior fusiform gyrus and inferior medial prefrontal cortex in social perception by Geday, Jacob, Gjedde, Albert, Boldsen, Anne-Sophie, Kupers, Ron

“…Previous studies have shown that during the presentation of emotionally loaded visual stimuli, activity increases in the visual and limbic cortices. This study…”

Attention, emotion, and deactivation of default activity in inferior medial prefrontal cortex by Geday, Jacob, Gjedde, Albert

“…Attention deactivates the inferior medial prefrontal cortex (IMPC), but it is uncertain if emotions can attenuate this deactivation. To test the extent to…”
