Abstract excerpt

The tau mutation is a semi-dominant autosomal mutation which, in homozygotes, accelerates the period of the circadian activity cycle by approximately 4 h. In mammals, the circadian system contributes to seasonal photoperiodic time measurement by generating a repeated daily melatonin signal during...
