ABSTRACT
Since the pioneer work of Hans Berger (1929) it has become a usual procedure both in the clinic and in the laboratory to record changes in electrical activity of the brain by means of surface electrodes fixed to the scalp. Electrodes are generally placed at standard positions that are reflected in Fig. 5.1. These positions are indexed by letter-figure combinations, indicating the left or right brain area above which the electrodes are fixed. The write-out of changes in potential recorded between pairs of electrodes is known as the electroencephalogram (EEG). In the present chapter a review is given of potential changes that are coupled with the occurrence of circumscribed events. From the set of event-related potentials (ERPs) we discuss only ERP’s related to the planning and execution of a movement. Electrode positions, used in the recording of an electroencephalogram (EEG). F = frontal, C = central, P = parietal, O = occipital, T = temporal. Even subscripts: rigtt side of the scalp. Odd subscripts: left side of the scalp. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315627991/0c71495e-218e-4bc2-82cb-5b11072e45ab/content/fig5_1_B.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
