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.

Ca²⁺-free synaptotagmin-1 binds to neuronal SNARE complexes anchored on nanodiscs, and Ca²⁺ releases this interaction to induce tight, specific binding to PIP₂-containing membranes.

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.

Developmental hearing loss causes perceptual deficits that are best explained by degraded auditory cortical encoding that is recorded during task performance.

Whereas in a paradigmatic structure an SM protein chaperone clamps its client SNARE shut, a second structure demonstrates that an SM protein can also hold its SNARE open to promote assembly.

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.

Memory guides attention by enabling preparation for upcoming states in the hippocampus and medial prefrontal cortex.

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.

Call-based vocal communication of individually recorded zebra finches changes in social groups across reproductive stages and is related with successful egg laying.
