Abstract

Suppression of the 8-13 Hz (Mu) frequency EEG band recorded over sensorimotor cortex has been postulated as an index of mirroring activity in the brain. Using repetitive transcranial magnetic stimulation (rTMS), recent research has also shown that temporary disruption of activity in the left inferior frontal gyrus (LIFG; presumably implicated in mirroring activity) eliminates Mu suppression during social perception tasks, while also decreasing performances. Based on these, and also other evidences showing that EEG Mu suppression is reduced during exposure to ambiguous, Rorschach inkblot designs eliciting “feeling of movement”, we aimed at further investigating the link between mirroring activity in the brain and exposure to the Rorschach, ambiguous stimuli.
