• A tone (500 c/sec, 95 phons, 5 sec in duration) was presented to a cat during slow-wave sleep until the temporal cortex failed to desynchronize on 3 successive trials, being followed by a dishabituation trial when the tone of a different frequency (1000 c/sec) was given. Data with 10 adult cats showed that cortical desynchronization decreased and disappeared with trials and recovered, although not completely, on the dishabituation trial. Similar data were obtained in hippocampal theta activity except that it habituated faster than the cortical activity. Mean theta frequency also decreased less markedly with trials. Peripheral responses (head movement, respiratory response) failed to be elicited in some cats even on trial 1 but as a group they were habituated and extinguished but not dishabituated.
