Modulation of Spontaneous Brain Activity During Mental Imagery

reportActive / Technical Report | Accession Number: ADA209918 | Open PDF

Abstract:

Magnetic measurements of average power of human alpha activity over the occipital and parietal areas of the scalp reveal spatially selective suppression when abstract figures are briefly presented visually. The duration of suppression increases along with reaction time during a search of visual memory. This implies that the visual system is involved in mental imagery. Keywords Brain function Neural activity.
