Abstract

The phase angle of entrainment of golden hamster wheel-running activity was determined before and after bilateral destruction of the intergeniculate leaflet (IGL). Animals were maintained under continuous dim light which rhythmically varied in intensity (10-5 lux) in the form of a sine wave with a 24 h period. The phase angle of entrainment changed significantly following IGL ablation suggesting a role for the IGL in entrainment.
