Food anticipatory activity and photic entrainment in food-restricted BALB/c mice
How restricted feeding affects activity and light response in BALB/c mice
AI simplified
Abstract
Food anticipatory activity (FAA) rhythms were evident in all BALB/c mice evaluated.
- Mice exhibited varying levels of FAA, from robust to weak and variable.
- Advancing transients of nocturnal activity were observed, leading to a significant shortening of nocturnal activity bouts.
- Nocturnal activity was shown to expand after restricted feeding through a series of delaying transients.
- Following a period of constant dark with unrestricted food, the phase of activity was advanced compared to control tests.
- Restricted feeding in constant dark conditions resulted in some mice showing robust FAA alongside a free-running activity component.
