    Mapping quantal touch using 7 Tesla functional magnetic resonance imaging and single-unit intraneural microstimulation

    Rosa Maria Sanchez Panchuelo et al.
    The combination of intraneural microstimulation and 7T fMRI makes it possible to bridge the gap between first-order mechanoreceptive afferent input codes and their spatial, dynamic and perceptual representations in human cortex.

    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.

    Beta band oscillations in motor cortex reflect neural population signals that delay movement onset

    Preeya Khanna, Jose M Carmena
    Using a sequential neurofeedback-arm reaching task, a new link is established among population neural activity patterns, generation of beta oscillations, and motor behavior changes.

    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.

    Distributed task-specific processing of somatosensory feedback for voluntary motor control

    Mohsen Omrani et al.
    Somatosensory feedback is transmitted to many sensory and motor cortical regions within 25 milliseconds and ongoing behavioural tasks alter the spatiotemporal pattern of this perturbation-related activity, supporting rapid motor responses to attain behavioural goals.

    Minimally dependent activity subspaces for working memory and motor preparation in the lateral prefrontal cortex

    Cheng Tang et al.
    The evidence of subspace computation in the lateral prefrontal cortex provides insights into the neural mechanisms underlying cognitive flexibility and interference between different cognitive processes.

    Movement initiation and grasp representation in premotor and primary motor cortex mirror neurons

    Steven Jack Jerjian et al.
    Mirror neurons, including corticospinal neurons, in primary motor cortex of macaque monkeys, clearly dissociate between execution and observation of grasping actions while ventral premotor cortex (F5) maintains a similar representation.
    1. Neuroscience

    How many neurons are sufficient for perception of cortical activity?

    Henry WP Dalgleish et al.
    Targeted optogenetic activation of small ensembles of neurons is sufficient to trigger a behavioral report while recruiting matched network suppression, suggesting exquisite sensitivity despite network mechanisms that maintain sparseness.

    Neural ensemble dynamics in dorsal motor cortex during speech in people with paralysis

    Sergey D Stavisky et al.
    Neurons in human dorsal motor cortex, an area involved in controlling arm and hand movements, are also active – and show similar ensemble dynamics – during speaking.
    1. Neuroscience

    Conservation of preparatory neural events in monkey motor cortex regardless of how movement is initiated

    Antonio H Lara et al.
    Voluntary movements are preceded by a temporally flexible preparatory neural process that is present regardless of whether movement is initiated rapidly or thoughtfully.
