    Electrocorticography is superior to subthalamic local field potentials for movement decoding in Parkinson’s disease

    Timon Merk, Victoria Peterson ... Wolf-Julian Neumann
    Advanced machine learning based brain signal decoding of grip-force as a proxy for movement vigor shows Parkinson's disease related performance reduction, suggestive of a loss of cortical vigor encoding in the absence of dopamine.

    Electrocorticographic dissociation of alpha and beta rhythmic activity in the human sensorimotor system

    Arjen Stolk, Loek Brinkman ... Ivan Toni
    Direct cortical recordings in humans link the spectral structure of local field potentials to inhibition/disinhibition mechanisms coordinating sensorimotor neuronal populations during movement imagery.

    Cortical network architecture for context processing in primate brain

    Zenas C Chao, Yasuo Nagasaka, Naotaka Fujii
    Large-scale electrocorticography and big data analysis of brain-wide neuronal interactions reveal the architecture of network information flow for context processing in primate brain.

    Targeted cortical reorganization using optogenetics in non-human primates

    Azadeh Yazdan-Shahmorad, Daniel B Silversmith ... Philip N Sabes
    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.

    Waveform detection by deep learning reveals multi-area spindles that are selectively modulated by memory load

    Maryam H Mofrad, Greydon Gilmore ... Lyle Muller
    A new computational approach for detecting sleep waveforms reveals that the 11–15 Hz sleep 'spindle', a neural rhythm implicated in memory consolidation, co-occurs widely across cortex much more often than previously thought.

    Phase-amplitude coupling supports phase coding in human ECoG

    Andrew J Watrous, Lorena Deuker ... Nikolai Axmacher
    Electrocorticography (ECoG) reveals that phase-amplitude coupling relates to phase-dependent coding in the human brain.

    Concurrent decoding of distinct neurophysiological fingerprints of tremor and bradykinesia in Parkinson’s disease

    Peter M Lauro, Shane Lee ... Wael F Asaad
    Motor signs of Parkinson’s disease such as tremor and bradykinesia are independently expressed and exhibit distinct signatures of neural activity that can independently decoded from subthalamic and cortical recordings using interpretable machine learning.

    Left hemisphere dominance for bilateral kinematic encoding in the human brain

    Christina M Merrick, Tanner C Dixon ... Richard B Ivry
    An electrode-wise encoding model based on physiological recordings from the cortical surface revealed a striking hemispheric asymmetry where the encoding of ipsilateral movement was stronger in the left hemisphere compared to the right hemisphere.

    Constructing the hierarchy of predictive auditory sequences in the marmoset brain

    Yuwei Jiang, Misako Komatsu ... Liping Wang
    fMRI and high-density ECoG recordings reveal a hierarchical gradient along the auditory pathway for auditory sequence processing in the marmoset brain.

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

    Laura D Lewis, Giovanni Piantoni ... Patrick L Purdon
    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.
