Abstract
It is hypothesized that amplitudes of evoked cortical association responses will be inversely related to degree of “attention”, the latter being operationally defined as the extent of behavioral orienting to a stimulus. Cats with implanted cortical recording electrodes were given series of clicks through either of two oppositely placed speakers. The degree and accuracy of the orienting response was rated, and evoked cortical association response simultaneously recorded, for each click. As predicted, the degree of the orienting response decreased significantly over trials, while the amplitude of the evoked association response exhibited a concomitant increase over trials.
