    Stimulus background influences phase invariant coding by correlated neural activity

    Michael G Metzen, Maurice J Chacron
    Building on previous work (Metzen et al., 2016), a combination of neurophysiological and behavioral approaches reveals that changes in the background strongly impacts invariant coding and perception of behaviourally relevant signals.

    The inhibitory microcircuit of the substantia nigra provides feedback gain control of the basal ganglia output

    Jennifer Brown et al.
    Negative feedback signals within the substantia nigra regulate the output of the basal ganglia, with implications for disorders such as Parkinson's disease.

    Calcium-dependent electrostatic control of anion access to the pore of the calcium-activated chloride channel TMEM16A

    Andy KM Lam, Raimund Dutzler
    Ion conduction in the calcium-activated chloride channel TMEM16A is directly regulated by calcium, which binds to a site close to the pore thereby shaping the electrostatics at its intracellular entrance.

    Distinct modes of endocytotic presynaptic membrane and protein uptake at the calyx of Held terminal of rats and mice

    Yuji Okamoto et al.
    Capacitance measurements and pH imaging reveal distinct modes of uptake for endocytotic presynaptic membrane and proteins.

    Ventral pallidal encoding of reward-seeking behavior depends on the underlying associative structure

    Jocelyn M Richard et al.
    Reward-related cues elicit phasic changes in activity in ventral pallidum neurons, which predict and functionally contribute to the speed of behaviors trained on the basis of act-outcome, but not stimulus-outcome, contingencies.

    A genetic link between discriminative fear coding by the lateral amygdala, dopamine, and fear generalization

    Graham L Jones et al.
    Discrimination of predictive and non-predictive fear stimuli requires plasticity in the lateral amygdala that is regulated by midbrain dopamine neurons.

    Capturing the temporal evolution of choice across prefrontal cortex

    Laurence T Hunt et al.
    Experiments in macaques and humans reveal time-varying changes in prefrontal cortex activity that occur during decisions based on costs and benefits.

    Hypoexcitability precedes denervation in the large fast-contracting motor units in two unrelated mouse models of ALS

    María de Lourdes Martínez-Silva et al.
    The most vulnerable motor units lose a fundamental firing property before the denervation of their muscle fibers in ALS mice, changing our view of the role of excitability in neurodegeneration.

    Cholinergic modulation of hippocampal calcium activity across the sleep-wake cycle

    Heng Zhou et al.
    Dynamic calcium activity in the hippocampus changes markedly across behavioral and physiological states and depends on muscarinic acetylcholine receptor activation.

    First spikes in visual cortex enable perceptual discrimination

    Arbora Resulaj et al.
    A brief time window of visually evoked activity in mouse primary visual cortex is sufficient for perceptual discrimination.
