TL;DR: In this article , a parsimonious conceptualization of brain state as the fundamental building block of whole-brain activity offers a common framework to relate findings across scales and species, and examples of the diverse techniques commonly used to study brain states associated with physiology and higher-order cognitive processes.

TL;DR: Wide-field mesoscopic calcium imaging is used to monitor cortical dynamics in awake mice and an approach to quantify rapidly time-varying functional connectivity is developed, which provides insight into the relationship between neural signals and behavior.

TL;DR: Simultaneous in vivo imaging reveals that endogenous correlated spontaneous activity instructs axonal connectivity with subcellular precision, following Hebb's law, where synchronized activity promotes branch addition and desynchronized activity leads to elimination, refining neural circuits before sensory experience.

TL;DR: In this paper , the authors stabilize the eye to access in situ retinal dynamics with optical techniques in awake mice, and demonstrate that retinal activity is strongly modulated by movement through H1R-dependent histaminergic transmission in vivo, even at the amacrine cell level.
