Self-Referential Processing Effects of Non-invasive Brain Stimulation: A Systematic Review

Systematic reviews of neuroimaging studies confirm stimulus-induced activity in response to verbal and non-verbal self-referential processing (SRP) cortical midline structures, temporoparietal cortex insula. Whether SRP can be causally modulated by way non-invasive brain stimulation (NIBS) has also been investigated several studies. Here we summarize the NIBS literature including 27 task-based comparing between tasks. The differed design, experimental tasks parameters. Results support role left inferior parietal lobule (left IPL) for medial prefrontal when valenced stimuli were used. Further, results roles bilateral lobe (IPL, posterior cingulate cortex), sensorimotor areas (the primary sensory motor cortex, premotor extrastriate body area) insula (bodily self-consciousness). We conclude that may differentially modulate targeting corresponding areas.
