      Reference

      nur2/nur3 transheterozygosity do not have consistent effects on sleep. nur2/nur3 transheterozygotes show increased mid-nighttime arousal by light stimuli (i.e. more individuals get aroused by a light pulse and then show higher speed of movements and higher sleep latency than controls) and by odor stimuli (i.e. more individuals get aroused by a concentrated 3-Octanol odor than controls). Following 6h of sleep deprivation during nighttime, transheterozygotes show delayed sleep recovery despite of no changes in overall sleep duration over the following 12h daytime period, as compared to heterozygous controls.
