Abstract
Cats were implanted with chronic bipolar electrodes either in the inferior colliculus (IC) or in the lateral tegmental nucleus (LTN). The animals were then trained in a Y-maze to make a differential response to an 800-Hz and a 1,000-Hz tone. On a series of test trials, electrical brain stimulation at either 800 or 1,000 pulses /sec was substituted for the tonal stimuli used during original training. Cats with IC electrodes tended to behave as though they were responding to the tonal stimuli, while LTN animals did not. These data suggest that direct electical brain stimulation can be a useful technique in the study of sensory coding.
