Zusammenfassung
We have studied the differential activation of visual areas V1 and V5 during early visual information processing in eight healthy subjects in a full-field pattern reversal task (black and white checkerboard). Magnetic fields were registered with a whole-head magnetometer system (Magnes 2500 WH, 4D-Neuroimaging) with 148 SQUIDS and averaged relative to stimulus onset. The underlying current source density was determined by means of the magnetic field tomography [1]. Brain areas displaying stimulus-locked responses were anatomically identified with anatomical probability maps [2]. Our approach revealed that V1 and…
