Summary
A phase response curve was obtained for the locomotor activity rhythm of the rat,Mus norvegicus albicus, by interrupting a free-running rhythm with light signals of short duration. The response curve obtained was continuous and had the switch-over point at the position of 2 h before the acrophase, followed by the portion of advancing phase shift. The pattern of the curve was typical for the nocturnal rodent.
