Summary
This thesis examines how mammalian circadian clocks enable anticipation of significant daily events through a context-entrainable oscillator (CEO), using conditioned place avoidance and preference paradigms in mice. The findings are largely methodological and suggest improvements to experimental design, with limited direct practical implications for lighting design at this stage.
Key Findings
- Circadian-gating of anticipatory behavior could not be reliably demonstrated with the current conditioned place preference (CPP) paradigm in C57BL/6 mice.
- Two possible explanations were proposed for the null result: insufficient visual distinction between contexts, or stimulus strength strong enough to cause generalization across the temporal dimension.
- The study proposes improved paradigms with stronger visual cues and adjusted appetitive stimuli for future investigation of multiple time memory (MTM).
