EEG MU RHYTHMS DURING ACTION OBSERVATION ARE MODULATED BY EMOTIONAL VALENCE
Journal Title: Acta Neuropsychologica - Year 2016, Vol 14, Issue 2
Abstract
Background: The mu rhythm as an 8–13 Hz component generated by the primary sensorimotor cortex, has been noted as a promising marker of the human mirror neuron system (MNS). The MNS discharge both when a movement is executed and when that same movement is observed and imagine, has been considered to facilitate emotion processing. But whether emotional stimulus can influence the ensuing MNS is unclear. The purpose of this study is to understand emotional valence among various factors that can influence the activation of mirror neurons.Material/Methods: Fifteen healthy female subjects viewed videos of either transitive hand action scenes or still objects for imagery, both preceded by either a neutral, positive, or negative stimulus from the International Affective Picture System. The EEG activity in the Mu rhythms was evaluated by a method which segregated the time-locked for each block.Results: Our results showed Mu suppression increased during observation and imagery following a negative emotional valence.Conclusions: These data support the notion that the human mu rhythm is suppressed by action observation and imagery, emotional valence can influence the mu suppression. That results are expected to provide information on the neuropsychology related to the intervention of cognitive rehabilitation(observation or imaging).
