Based on the importance of PDF positive neurons for behavioral rhythmicity in Drosophila and the cockroach, and on information obtained in several lesion studies, the

Midazolam (D) and fentanyl (E) injections during the late subjective night or early subjective day induce large phase delays in the activity offset, while the activity onset

Our experiments indicated that a light pulse blocks phase advances of wheel running activity rhythms induced by fentanyl at CT 6, whereas application of light by itself is

It has long been assumed that the timing of sleep is regulated independently of the need for sleep 6,22 , but more recent data indicate that there is a continuous interaction

(A and B) The advances in the Per1-luc bioluminescence rhythm as well as in the in vitro electrical activity were significantly different from the responses of in vivo

What we presently know about the interregional entrainment pathways can be summarized as follows: (1) The ventral SCN receives dense retinal input [8]; (2) the ventral SCN

Ze suggereren dat het onvermogen van het lichaam om zich snel aan te passen aan een verschuiving van de licht-donker cyclus niet veroorzaakt wordt door de circadiane pacemaker
