Despite their extreme morphologies, snakes display a global regulatory strategy of their Hox genes similar to that implemented by mammals with, however, important modifications in enhancer specificity.
A molecular atlas of the chick retina provides a comprehensive classification and characterization of 136 cell types, yielding novel insights into retinal structure, function, development, and evolution.
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.
