Distinct brain states govern resting state functional architecture revealed by neurophysiologically defined simultaneous optic-fiber-based calcium recordings and task-free functional magnetic resonance imaging (fMRI) in rats.
A quantitative video tracking analysis reveals that to gain the nutrients they need, flies change their decisions to exploit foods with different nutrient contents and explore the environment according to their internal amino acid and reproductive states.
Sub-second pontine waves functionally interact with hippocampal population activity in a state-dependent manner across sleep states, while brainstem ensemble dynamics exhibit slow, long-lasting state-predictive activity.
In depth characterization of gene expression in the mouse hypothalamus will facilitate understanding of the molecular pathways that affect metabolic traits and discovers new genes associated with these pathways.
The excessive behavioral variability associated with adolescence is the result of greater instability of widespread or global gain signals which produces greater variability in the amplitude of expression of whole-brain states of task-related activity.
