    Thalamocortical synapses in the cat visual system in vivo are weak and unreliable

    Madineh Sedigh-Sarvestani et al.
    A characterization of LGN-V1 synaptic transmission properties demonstrates thalamocortical synapses in vivo are weak and unreliable, but biologically constrained models show they efficiently drive cortex.

    Corticothalamic gating of population auditory thalamocortical transmission in mouse

    Baher A Ibrahim et al.
    Sensory stimulation produces stochastic population responses in the cortex that are governed by layer 6 cortico-reticular projections that modulate thalamic synchrony.

    Three rules govern thalamocortical connectivity of fast-spike inhibitory interneurons in the visual cortex

    Yulia Bereshpolova et al.
    In the visual system, three rules guide the thalamocortical connectivity of cortical fast-spike interneurons and are key to understand the potent and broadly tuned feed-forward inhibition that they generate.

    Variation of connectivity across exemplar sensory and associative thalamocortical loops in the mouse

    Arghya Mukherjee et al.
    Compared to a sensory thalamocortical circuit, the mediodorsal thalamus preferentially innervates prefrontal cortical interneurons, and enhancing excitability of this thalamic structure drives prefrontal activity patterns that are dominated by inhibition.

    Thalamocortical and corticothalamic pathways differentially contribute to goal-directed behaviors in the rat

    Fabien Alcaraz et al.
    Adaptive decision-making critically depends on antiparallel flows conveying distinct information within thalamocortical circuits, highlighting directionality of functional exchanges as a neural principle potentially at play in virtually any brain circuit with reciprocal projections.

    Cellular and neurochemical basis of sleep stages in the thalamocortical network

    Giri P Krishnan et al.
    A computational model of the thalamocortical network explains sleep stages by the coordinated variations in the level of neuromodulators and predicts differences of sleep pattern in human, cat and mouse recordings.

    A thalamocortical circuit for updating action-outcome associations

    Virginie Fresno et al.
    Disconnection of the orbitofrontal cortex from the submedius nucleus but not the mediodorsal thalamus prevented rats to respond adaptively following action-outcome reversal, showing differential involvement of these thalamocortical circuits.

    Binocular matching of thalamocortical and intracortical circuits in the mouse visual cortex

    Yu Gu, Jianhua Cang
    The binocular matching of thalamic inputs to layer 4 cortical neurons initiates before that of intracortical inputs.

    Astrocytes refine cortical connectivity at dendritic spines

    W Christopher Risher et al.
    Spines with multiple excitatory contacts are potential sites for competition between thalamic and cortical axons, which is regulated by the astrocytes through the secreted synaptogenic protein hevin.

    Thalamic input to auditory cortex is locally heterogeneous but globally tonotopic

    Sebastian A Vasquez-Lopez et al.
    Layers 1 and 3b/4 of auditory cortex receive surprisingly heterogeneous but tonotopically matching input from the thalamus.
