Results We recorded SUA and MUA as well as LFPs from two tetraplegic participants (JJ and RD) implanted with Utah arrays targeting the motor and posterior parietal cortices. Participant JJ had 96-channel arrays in the hand knob area of the primary MC and superior parietal lobule (SPL). Participant RD had 64-channel arrays in the medial motor cortex (MCM), lateral motor cortex (MCL), and SPL. An additional array targeting the supramarginal gyrus (SMG) in RD was excluded from all analyses.

Duration-modulated neural population dynamics in humans during BMI controls

Abstract The motor cortex (MC) is often described as an autonomous dynamical system during movement execution. In an autonomous dynamical system, flexible movement generation depends on reconfiguring the initial conditions, which then unwind along known dynamics. An open question is whether these dynamics govern MC activity during brain-machine interface (BMI) control.

Abstract Understanding disorders of consciousness (DOC) remains one of the most challenging problems in neuroscience, hindered by the lack of experimental models for probing mechanisms or testing interventions.
