Organisms on Earth exhibit precise 24-hour rhythms driven by the periodicity of natural light. Even in the absence of cyclic light exposure, they maintain near-24-hour rhythms, indicating the presence of an endogenous clock regulating internal biological rhythms. In mammals, this endogenous clock is located in the suprachiasmatic nucleus (SCN) of the brain, known as the master clock. Biological rhythms are influenced by multiple spatial scales, including clock gene levels, neuronal levels, master clock network levels, and social network levels. This report will focus on: the impact of master clock network structure on neuronal synchronization.
