    A comprehensive excitatory input map of the striatum reveals novel functional organization

    Barbara J Hunnicutt et al.
    The first comprehensive map of all excitatory inputs to the mouse striatum is presented and used to define and demarcate striatal subdivisions, including a previous unappreciated novel subdivision in the posterior striatum.

    Medium spiny neurons activity reveals the discrete segregation of mouse dorsal striatum

    Javier Alegre-Cortés et al.
    Analysis of slow wave brain state unravels the functional connectivity and the biological substrate of the rodent dorsolateral and dorsomedial striatum, demonstrating its organization in two non-overlapping circuits.

    Oxytocin improves behavioral and electrophysiological deficits in a novel Shank3-deficient rat

    Hala Harony-Nicolas et al.
    The production, validation and study of a novel rat model for Phelan McDermid Syndrome shows an ameliorative effect of oxytocin on both social and attentional deficits.

    Attenuation of dopamine-modulated prefrontal value signals underlies probabilistic reward learning deficits in old age

    Lieke de Boer et al.
    Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.

    Disruption of Nrxn1α within excitatory forebrain circuits drives value-based dysfunction

    Opeyemi O Alabi et al.
    Disruption of the disease-associated synaptic adhesion molecule Neurexin1a in cortical excitatory neurons perturbs decision making and disrupts value-associated neural activity in downstream striatal circuits.

    Motor thalamus supports striatum-driven reinforcement

    Arnaud L Lalive et al.
    While the basal ganglia have long been thought to mediate learning through dopamine-dependent striatal plasticity, their regulation of motor thalamus plays an unexpected and critical role in reinforcement.

    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.

    Causal contribution and dynamical encoding in the striatum during evidence accumulation

    Michael M Yartsev et al.
    Behavioral, pharmacological, optogenetic, electrophysiological and computational analyses suggest that the anterior dorsal striatum is a causal node in the network responsible for evidence accumulation.

    A cholinergic feedback circuit to regulate striatal population uncertainty and optimize reinforcement learning

    Nicholas T Franklin, Michael J Frank
    Computational modeling suggests that feedback between striatal cholinergic neurons and spiny neurons dynamically adjusts learning rates to optimize behavior in a variable world.
