Diurnal variation of learning and memory and molecular approach in mice and nonhuman primates
Cognitive functions like learning and memory depend on the time of day in various organisms. We have demonstrated that long-term recognition memory performance revealed an apparent diurnal/circadian change with the peak during the early night in nocturnal mice. SCOP (PHLPP1b) is a key molecule regulating hippocampus-dependent long-term memory in mice. The amounts of SCOP in the hippocampus exhibit robust circadian changes. Long-term memory formation in recognition memory is regulated by the circadian clock through SCOP dynamics in the hippocampal CA1 in nocturnal mice. Whether diurnal changes
