Müller, E. Göpfert, L. Schlykowa, D. Anke] A ‘motion onset VEP' was elicited by the onset of a pattern drift. The amplitude of the most distinct wave (A n200) was determined on the following stimulation conditions: eccentricity, 0 to 23deg; velocity, 1.5 to 16deg/s; spatial frequency, 0.19 to 2.1c/deg; and stimulation field size, 0.2 to 160 deg2. A n200 remained constant at any degree of eccentricity if stimulation field size, velocity, and spatial frequency were M-scaled according to Rovamo-Virsu's M-equations. A n200 decreased as a function of eccentricity if field size and velocity were kept constant (spatial frequency had minimal effect). The size of the cortical representation field (Sc) in this case varied with change in eccentricity (stimulation field size constant). In another experiment, it varied by change in stimulation field size (eccentricity constant). For both conditions, A n200 was proportional to log Sc.
