Per1tm1Drw mutation (2 available); any Per1 mutation (63 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• mice exhibit impaired learning and memory in the Morris water maze
• mice are impulsive in the open-field
• mice are hyperactive and impulsive in the open-field, traveling a longer distance in 5 min, and showing an increase in the number of line crossings

homeostasis/metabolism
• brain dopamine levels are lower in females, but not males

N normal phenotype
behavior/neurological
• in free-running conditions, the period of temperature rhythm is longer than in wild-type mice
• 9 of 11 mice become arrhythmic after 10 to 14 days when transferred to dark-dark conditions unlike wild-type mice
• for 3 weeks in dark-dark conditions, one mouse exhibited reduced circadian rhythm amplitude compared to in wild-type mice
• during the 12-hour recovery after 6 hours of prolonged waking, mice exhibit less waking and more short wave sleep compared to similarly treated wild-type mice
• in free-running dark-dark conditions mice fail to exhibit a change in REM sleep unlike similarly treated wild-type mice

nervous system
• recovery after 6 hours of prolonged waking, mice exhibit an increase in delta power lasting 9 hours during the recovery sleep period compared with wild-type mice in which it lasts 3 hours

behavior/neurological
• mice immediately lose their rhythmicity when transferred into dark-dark conditions (J:69626)
• in free-running conditions, mice become arrhythmic immediately under dark-dark conditions unlike similarly treated wild-type mice (J:95746)
• during the 12-hour light segment, mice wake more and have less slow wave sleep compared to wild-type mice
• during the last two-third of the lights-on period, mice exhibit more wakefulness than wild-type mice
• at midday, mice exhibit less REM sleep than wild-type mice
• in dark dark conditions, mice exhibit arrhythmic pattern of time spent in wakefulness, short wave sleep, and REM sleep unlike similarly treated wild-type mice
• however, the amount of sleep obtained in dark-dark conditions is normal
• during entrained conditions, mice exhibit longer wake bouts during the dark period compared with the light period unlike in wild-type mice
• during entrained conditions, mice exhibit longer short wave sleep and REM sleep bouts during the light segment compared with wild-type mice
• arrhythmic mice exhibit even distribution of wake, short wave sleep, and REM bouts during subjective light and dark periods unlike wild-type mice

homeostasis/metabolism
• the acrophase of core temperature is phase-advanced compared to in wild-type mice

nervous system
• recovery after 6 hours of prolonged waking, mice exhibit an increase in delta power lasting 12 hours during the recovery sleep period compared with wild-type mice in which it lasts 3 hours
