behavior/neurological

abnormal circadian behavior phase ( J:98340 )

• following exposure to prolonged light the magnitude of the induced phase delay is significantly larger compared to heterozygous and wild-type controls

abnormal circardian behavior entrainment ( J:98340 )

• impaired entrainment to long day periods under dim light conditions

• mice fail to entrain to long day periods under skeleton light conditions (L/D/L/D, 0.5/16/0.5/7)
