Abstract
Implanted electrodes in the dorsal hippocampus and the anterior and posterior cortex of 5 male Holtzman albino rats. The EEG arousal response initially produced in sleeping Ss by the presentation of an auditory stimulus habituated to an asymptote after 1 or 2 stimulus presentations. The initial responsiveness to the tone did not recover over as long as 30 days without stimulation. The habituation could not be explained by excitability changes unrelated to stimulus presentations. It is concluded that nonreinforced presentations of a stimulus can produce a long-term change in the CNS. (PsycINFO Database Record (c) 2006 APA, all rights reserved)Keywords
