    Supramammillary nucleus synchronizes with dentate gyrus to regulate spatial memory retrieval through glutamate release

    Yadong Li et al.
    Multi-fiber photometry recording and circuit-based manipulation in vivo identify a long-range SuM-DG circuit linking two highly correlated subcortical regions to regulate spatial memory retrieval through SuM glutamate transmission.

    GABA neurons in the ventral tegmental area regulate non-rapid eye movement sleep in mice

    Srikanta Chowdhury et al.
    Functional identification of GABAergic neurons in the ventral tegmental area as a important neuronal subpopulation regulating non-rapid eye movement (NREM) sleep in mice.

    Learning shapes the aversion and reward responses of lateral habenula neurons

    Daqing Wang et al.
    Neurons in the lateral habenula are activated by pain, bitterness and social defeat, and their responses are dynamically shaped by learning, suggesting a role in experience-dependent selection of behavioral actions to stressors.

    Motor context dominates output from purkinje cell functional regions during reflexive visuomotor behaviours

    Laura D Knogler et al.
    Purkinje cells of the cerebellum, a conserved vertebrate brain region important for sensorimotor integration, receive sensory and motor information from distinct input streams and are functionally clustered into modules reflecting the larval zebrafish's behavioral repertoire.

    Dopamine neurons drive fear extinction learning by signaling the omission of expected aversive outcomes

    Ximena I Salinas-Hernández et al.
    Dopamine signaling is necessary for normal fear extinction learning.

    Misaligned feeding impairs memories

    Dawn H Loh et al.
    The time at which mice consume food can dramatically affect hippocampal-dependent biochemistry, physiology, and learned behavior.

    Different neuronal populations mediate inflammatory pain analgesia by exogenous and endogenous opioids

    Xin-Yan Zhang et al.
    Exogenous opioid analgesia is mediated by MORs expressed in glutamatergic neurons, whereas endogenous opioid analgesia is mediated by MORs expressed in GABAergic neurons.

    Probabilistic, spinally-gated control of bladder pressure and autonomous micturition by Barrington’s nucleus CRH neurons

    Hiroki Ito et al.
    Ponto-spinal CRH neurons in Barrington’s nucleus are a core component of an inferential circuit that regulates autonomous micturition and generates voids when the bladder is full.

    Nitric oxide radicals are emitted by wasp eggs to kill mold fungi

    Erhard Strohm et al.
    To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.

    Coordination of rapid cholinergic and dopaminergic signaling in striatum during spontaneous movement

    Mark Howe et al.
    Optical recordings reveal previously unknown neuromodulator dynamics in the striatum during animal movements that suggest a new interpretation of the underpinnings of bradykinetic movements exhibited in Parkinson's Disease patients.
