ABSTRACT
The link between perception, cognition, and motor processes on the one hand and brain processes on the other has been known since antiquity. Knowledge about this correspondence stemmed mainly from the study of brain lesions and has been strengthened over the last decades by neuroanatomical and neurophysiological methods in animals. In the past few years, neuroimaging methods, such as positron emission tomography (PET), functional magnetic resonance imaging (fMRI), event-related brain potentials derived from electroencephalography, and magnetoencephalography (MEG) have corroborated this link for the human brain, which cannot be studied by invasive techniques.
