    Motor cortex signals for each arm are mixed across hemispheres and neurons yet partitioned within the population response

    Katherine Cora Ames, Mark M Churchland
    Neurons in motor cortex contain information about each arm, but these signals are separated into different dimensions, allowing separate control of each arm.

    Amygdala-ventral striatum circuit activation decreases long-term fear

    Susana S Correia et al.
    Behavior- or optogenetic-driven activation of a basolateral amygdala projection to the nucleus accumbens enhances infralimbic cortex activity and long-term fear extinction.

    Population response magnitude variation in inferotemporal cortex predicts image memorability

    Andrew Jaegle et al.
    Population response magnitude predicts how well an image will be remembered, in both monkey inferotemporal cortex and neural networks trained to categorize objects.

    A connectional hub in the rostral anterior cingulate cortex links areas of emotion and cognitive control

    Wei Tang et al.
    A hub in the rostral anterior cingulate cortex receives unusually high and functionally diverse inputs, providing a biological interface between motivation, incentive based learning, and decision making.

    Pathway-, layer- and cell-type-specific thalamic input to mouse barrel cortex

    B Semihcan Sermet et al.
    Two distinct thalamocortical pathways were found to provide differential excitatory synaptic input to distinct cell-types across layers of mouse primary somatosensory barrel cortex.

    Integrated externally and internally generated task predictions jointly guide cognitive control in prefrontal cortex

    Jiefeng Jiang et al.
    The dorsolateral prefrontal cortex integrates concurrent externally and internally generated predictions of task demand to guide information processing, while the medial prefrontal cortex corrects its prediction error based on actual task demand.

    A mutant with bilateral whisker to barrel inputs unveils somatosensory mapping rules in the cerebral cortex

    Nicolas Renier et al.
    The somatosensory cortex doesn't integrate mixed bilateral inputs, as partially uncrossing projections from the whiskers duplicates their representation by segregating lateralized inputs from each side of the head.

    Gyrification of the cerebral cortex requires FGF signaling in the mammalian brain

    Naoyuki Matsumoto et al.
    FGF signaling is crucial for gyrus formation, proliferation of outer radial glial cells and expansion of upper layers of the cerebral cortex in gyrencephalic mammals.

    Behavioral-state modulation of inhibition is context-dependent and cell type specific in mouse visual cortex

    Janelle MP Pakan et al.
    The three main types of inhibitory neurons in mouse primary visual cortex respond differently to locomotion in darkness and during visual stimulation, revealing context-dependent responses to changes in behavioral state.

    Feedforward motor information enhances somatosensory responses and sharpens angular tuning of rat S1 barrel cortex neurons

    Mohamed Khateb et al.
    Primary motor cortex afferents supra-linearly amplify the responses and sharpen angular tuning of neurons in the S1 barrel cortex.
