Axonal and synaptic failure suppress the transfer of firing rate oscillations, synchrony and information during high frequency deep brain stimulation.
Robert Rosenbaum,Andrew J. Zimnik,Fang Zheng,Robert Turner,Christian Alzheimer,Brent Doiron,Jonathan E. Rubin +6 more
TL;DR: The results support the idea that short term depression is a therapeutic mechanism of STN DBS that works as a functional lesion by decoupling the somatic spiking patterns of STn neurons from spiking activity in basal ganglia output nuclei.

Conservation of preparatory neural events in monkey motor cortex regardless of how movement is initiated.
Antonio H. Lara,Gamaleldin F. Elsayed,Gamaleldin F. Elsayed,Andrew J. Zimnik,John P. Cunningham,John P. Cunningham,Mark M. Churchland +6 more
TL;DR: The findings support the hypothesis that an appropriate preparatory state is consistently achieved before movement onset, and reveal that this process can consume surprisingly little time.
Independent generation of sequence elements by motor cortex
TL;DR: In this article, the authors investigated the contribution of primary motor and dorsal premotor cortex to the ability to perform two key processes at the same time in a two-reach sequence.

Postural control of arm and fingers through integration of movement commands
Scott T. Albert,Alkis M. Hadjiosif,Jihoon Jang,Andrew J. Zimnik,Demetris S. Soteropoulos,Stuart N. Baker,Mark M. Churchland,John W. Krakauer,Reza Shadmehr +8 more
TL;DR: The data suggest that the postural controller possesses a feedforward module that uses move commands to calculate a component of hold commands, which may arise within an unknown subcortical system that integrates cortical commands to stabilize limb posture.

TL;DR: Neuropixels 1.0-NHP as discussed by the authors is a high channel count linear electrode array designed to enable large-scale simultaneous recording in superficial and deep structures within the macaque or other large animal brain.
