    Synapse-specific opioid modulation of thalamo-cortico-striatal circuits

    William T Birdsong et al.
    By differentially modulating the two major excitatory inputs to the striatum, mu- and delta-opioid receptors regulate the balance between thalamic and cortical inputs to the striatum.

    Frequency-selective control of cortical and subcortical networks by central thalamus

    Jia Liu et al.
    Central thalamus relay neurons dynamically switch the activity of cortical and subcortical networks at distinct frequencies, providing a mechanism for this region's role in arousal regulation.
    1. Neuroscience

    Perineuronal nets control visual input via thalamic recruitment of cortical PV interneurons

    Giulia Faini et al.
    Accumulation of perineuronal nets around parvalbumin (PV)-positive inhibitory interneurons closes visual cortical plasticity by selectively down-regulating thalamic synapses onto PV cells in a sensory-dependent manner.

    Thalamo-cortical axons regulate the radial dispersion of neocortical GABAergic interneurons

    Sabrina Zechel et al.
    Glutamate derived from thalamo-cortical axons regulates the radial dispersion of interneurons in the developing mouse neocortex by limiting the level of expression of the K/Cl co-transporter KCC2.

    High-order thalamic inputs to primary somatosensory cortex are stronger and longer lasting than cortical inputs

    Wanying Zhang, Randy M Bruno
    Secondary thalamic nuclei may provide stronger, longer-lasting input to superficial layers of primary sensory cortex than other cortical areas can.

    Critical role for the mediodorsal thalamus in permitting rapid reward-guided updating in stochastic reward environments

    Subhojit Chakraborty et al.
    In monkeys, the integrity of the magnocellular subdivision of mediodorsal thalamus is important when using recent rewarded choices to promote persistence with a recently sampled choice during changing or uncertain reward guided-learning and decision-making tasks.

    An excitatory cortical feedback loop gates retinal wave transmission in rodent thalamus

    Yasunobu Murata, Matthew T Colonnese
    The absence of functional inhibition is a developmentally transient circuit property of corticothalamic feedback that is essential for the central transmission of spontaneous retinal waves.
    1. Neuroscience

    The paraventricular thalamus is a critical mediator of top-down control of cue-motivated behavior in rats

    Paolo Campus et al.
    A top-down circuit generating from the prelimbic cortex and projecting to the paraventricular nucleus of the thalamus mediates individual differences in cue-elicited responding by affecting subcortical dopamine-dependent incentive learning.
    1. Neuroscience

    Optogenetic feedback control of neural activity

    Jonathan P Newman et al.
    The 'Optoclamp' is a feedback control technology that enables precise, continuously updated, closed-loop optical control of neural firing both in vitro and in vivo.
    1. Neuroscience

    Disruption of thalamic functional connectivity is a neural correlate of dexmedetomidine-induced unconsciousness

    Oluwaseun Akeju et al.
    Patterns of communication between the thalamus and the cortex are correlated with anesthesia-induced loss of consciousness and recovery.
