    Targeted cortical reorganization using optogenetics in non-human primates

    Azadeh Yazdan-Shahmorad et al.
    Focal optogenetic stimulation strengthens functional connectivity between primary somatosensory and motor cortices in macaques, in a manner consistent with a Hebbian model of stimulus-driven plasticity.

    Subthalamic nucleus gamma activity increases not only during movement but also during movement inhibition

    Petra Fischer et al.
    Sudden stopping of rhythmic movement is associated with a pronounced increase of 60-90 Hz gamma oscillations in the subthalamic nucleus, which have formerly been regarded as favouring movement.

    High performance communication by people with paralysis using an intracortical brain-computer interface

    Chethan Pandarinath et al.
    New computer algorithms have allowed people with paralysis to achieve the highest reported typing performance using a brain-computer interface.

    The auditory representation of speech sounds in human motor cortex

    Connie Cheung et al.
    Brain activity patterns in motor cortex differ when we listen to speech as opposed to produce it.

    Propagated infra-slow intrinsic brain activity reorganizes across wake and slow wave sleep

    Anish Mitra et al.
    Human fMRI experiments reveal differences in the propagation of spontaneous brain activity during sleep versus wakefulness.

    Increasing suppression of saccade-related transients along the human visual hierarchy

    Tal Golan et al.
    Similar to spontaneous eye blinks perceptual stability, despite small saccades, is related to actively silencing transients in the high-level ends of both ventral and dorsal visual cortices, while activity in low-level visual cortex remains unstable.

    Frontal cortex selects representations of the talker’s mouth to aid in speech perception

    Muge Ozker et al.
    During speech perception, if auditory speech is not informative the frontal cortex will enhance responses in visual regions that represent the mouth of the talker to improve perception.

    Human intracranial recordings link suppressed transients rather than 'filling-in' to perceptual continuity across blinks

    Tal Golan et al.
    The brain ensures that blinks do not disrupt vision by deleting signals that represent discontinuities in visual input, rather than by recreating the missing input.

    A transient cortical state with sleep-like sensory responses precedes emergence from general anesthesia in humans

    Laura D Lewis et al.
    Intracranial recordings of human brain activity during awakening from general anesthesia exhibit a brief brain state not seen during loss of consciousness, in which stimuli elicit large electrophysiological responses that resemble those seen in sleep.
