ENP student Lorena Chanes has advanced our understanding of visual cognition. She manipulated the oscillatory activity of specific frequency bands in the right frontal eye field in order to reveal the role of beta and gamma frequencies in visual cognition. She found that high beta frequencies increased perceptual sensitivity but not response criterion. By contrast, gamma frequencies altered the response criterion but not perceptual sensitivity. For more details on this finding, check out the article at:
