Ultra-rapid sensory responses in the human frontal eye field region.

8 Jun 2009 Most of what we know about the human frontal eye field (FEF) is extrapolated from studies in animals. There is ample evidence that this region is crucial for eye movements. However, evidence is accumulating that this region also plays a role in ... Read more...

Emotional processing in PTSD: heightened negative emotionality to unpleasant photographic stimuli.

30 May 2009 This study evaluated evidence for 2 forms of emotional abnormality in posttraumatic stress disorder (PTSD): numbing and heightened negative emotionality. Forty-nine male veterans with PTSD and 75 without the disorder rated their emotional responses ... Read more...

High-frequency, long-range coupling between prefrontal and visual cortex during attention.

27 May 2009 Electrical recordings in humans and monkeys show attentional enhancement of evoked responses and gamma synchrony in ventral stream cortical areas. Does this synchrony result from intrinsic activity in visual cortex or from inputs from other ... Read more...
