Mouse lines carrying:
Kcnh8tm1.1Jmn mutation (0 available); any Kcnh8 mutation (91 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
nervous system
• absence of the normal day-night difference in mean repetitive firing rates of suprachiasmatic nucleus neurons resulting from a selective increase in nighttime firing rates
• no significant difference in mean +/- SEM input resistances, resting membrane potentials, and interspike intervals measured in daytime and nighttime unlike in wild-type neurons reflecting higher mean input resistances and depolarized membrane potentials in the nighttime

behavior/neurological
• despite loss of day-night difference in neuron firing rates, wheel running circadian rhythms are similar to wild-type controls
