Abstract
Expression of the clock gene Period1 in the retrosplenial cortex is necessary for incidental learning.
- Aging may disrupt the expression of Period1 in the retrosplenial cortex, which is associated with cognitive decline.
- Circadian rhythms can influence memory performance, suggesting a link between these two processes.
- The disruption of clock gene expression occurs in a brain region-dependent manner, potentially affecting memory differently in various areas.
- Findings indicate that clock genes have roles beyond regulating circadian rhythms, particularly in relation to learning and memory.
