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.

A combination of molecular dynamics simulations and X-ray diffraction data has been used to construct more realistic models of proteins and to provide new insights into their interactions with other proteins and biomolecules.

A new system for tagging activated neuronal population offers multiple advantages over existing systems based on immediate early genes, including greater sensitivity and specificity, and suitability for easy application in species other than mice.

Neuron populations in the lateral entorhinal cortex discriminate between memory-based contexts through both continuous "tonic" activity patterns as well as by their stimulus-evoked "phasic" responses.

Auditory cortical columns contain small subsets of neurons with highly synchronous activity (cNEs) that create robust sequences of coordinated activity suitable for enhanced information processing and signal transmission beyond the capability of individual neurons.

Dopamine neurons function as an ensemble to signal a multidimensional feature prediction error.

Neuron ensembles in the medial prefrontal cortex gradually develop codes for relevant, latent variables common across multiple experiences while – apparently independently – losing information about irrelevant, contextual variables unique to each experience.

In vivo calcium imaging reveals how odor identity is encoded in the activity of large, distributed ensembles of olfactory cortex neurons in mice.

Computational and theoretical models reveal mechanisms by which protein compartments assemble around enzymes and reagents to facilitate reactions in bacteria, allowing the identification of strategies for reengineering such compartments as customizable nanoreactors.

Ensemble fluidity, observed as synaptic turnover and temporal drift in neuronal patterns, supports memory-updating and flexibility while maintaining memory stability.
