Brain potentials of cognition and emotion in AS
We know that individuals with AS have a propensity for a happy demeanor and often have excessive laughter. We also know that they have pro-social behaviors that are distinctive from other types of genetic conditions. This study evaluated older individuals with Angelman who could cooperate in an experiment whereby subtle regional EEG patterns were studied after certain visual cues were presented. These cues involved pictures of individuals’ faces that were happy, sad or showed other types of visual cues.
