Influence of the Kindling Effect on Sleeping and Waking Rhythm

Abstract

(1), An electrophysiological study was made on the change of sleeping and waking rhythm in amygdaloid-kindled rabbits.
(2) Before the first stimulation, waking time was about 50% of 24 hours and REM sleep time was 4.7% of 24 hours. The former time was shorter and the latter was longer than those documented in previous reports.
(3) Waking time decreased to 40% and REM sleep time also decreased to 3.5% after the completion of kindling phenomenon.
(4) The tendency t h at waking time was shorter and slow-wave sleep time was longer before the first stimulation than those previously reported was reinforced after the completion of kindling phenomenon.
(5) Afte r the completion of kindling phenomenon, waking time decreased, slow-wave sleep time increased, and REM sleep time slightly decreased.
