    Distinct memory engrams in the infralimbic cortex of rats control opposing environmental actions on a learned behavior

    Nobuyoshi Suto et al.
    Current findings help reconcile the contradictory reports regarding the role of infralimbic cortex in the environmental control of appetitive behavior.

    State-dependent brainstem ensemble dynamics and their interactions with hippocampus across sleep states

    Tomomi Tsunematsu et al.
    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.

    Dopamine differentially modulates the size of projection neuron ensembles in the intact and dopamine-depleted striatum

    Marta Maltese et al.
    In addition to modulating firing rates, the neurotransmitter dopamine exerts a strong influence on the overall number of neurons in striatum that are recruited during behavior.

    Generalizable knowledge outweighs incidental details in prefrontal ensemble code over time

    Mark D Morrissey et al.
    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.

    How many neurons are sufficient for perception of cortical activity?

    Henry WP Dalgleish et al.
    Targeted optogenetic activation of small ensembles of neurons is sufficient to trigger a behavioral report while recruiting matched network suppression, suggesting exquisite sensitivity despite network mechanisms that maintain sparseness.

    Stable and dynamic representations of value in the prefrontal cortex

    Pierre Enel et al.
    The prefrontal cortex encodes both stable and dynamic representations of expected value, providing mechanisms to support robust as well as flexible access to value information during temporal delays.

    The brain in motion: How ensemble fluidity drives memory-updating and flexibility

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

    Stereotyped responses of Drosophila peptidergic neuronal ensemble depend on downstream neuromodulators

    Wilson Mena et al.
    The response of the peptidergic neurons that control a stereotyped behavior depends on the actions of a triggering neuropeptide, downstream neuropeptides and GABA inhibitory influences.

    Neural population dynamics in human motor cortex during movements in people with ALS

    Chethan Pandarinath et al.
    Neural ensemble activity in the human motor cortex contains dynamical structure that is independent of movement parameters and is not well-explained by current models.

    Recurrent circuit dynamics underlie persistent activity in the macaque frontoparietal network

    Eric Hart, Alexander C Huk
    Simultaneous recordings of neural ensembles in both the frontal and parietal cortices reveal how persistent activity can be maintained in the primate brain during visuospatial working memory.
