Entraining Brain Oscillations To Influence Facial Perception, Rosie Irwin
Entraining Brain Oscillations To Influence Facial Perception, Rosie Irwin
Summer Research
Relatively little is known about the role of brain oscillations in relation to cognitive function. While oscillations of all frequencies have be associated with most any neural process, no conclusive data has been found to support if oscillations are simply emergent or if they play a causal role in cognitive functions. To make headway on this problem, we employed entrainment, a technique used to synchronize brain oscillations. Entrainment was achieved by presenting subjects with alternating images of a neutral face and a scrambled face at 4 Hz such that the faces were presented at 2 Hz. After a few seconds …

Eeg Investigation Of Mirror-Neuron Activity Before And After Conscious Perception Of Emotion In Faces, Katie Singsank
Summer Research
While it is theorized that the human Mirror Neuron System (MNS) is used in action understanding and interpretation, how mu-wave suppression varies throughout the process of becoming conscious of a human facial expression and perceiving it has not been investigated. In the current study, EEG mu-wave suppression was used as an index of MNS activity. Data were collected while subjects viewed a 6 second clip in which static visual noise lifted over a period of 3 seconds revealing either a sad or angry face below which participants were asked to indicate the emotion with a keyboard button press. The image …
