A comparison of movement-related neuronal activities in cerebellar- and basal ganglia-recipient regions of the macaque thalamus

The paper compares movement-related neuronal activity in cerebellar- and basal ganglia-recipient regions of the macaque thalamus, finding distinct temporal and directional encoding patterns.

Movement-related activity in the internal globus pallidus of the parkinsonian macaque

This study examines how parkinsonism affects movement-related activity in the GPi of macaques, finding altered timing and magnitude of neuronal responses.

Large-scale high-density brain-wide neural recording in nonhuman primates

The paper introduces Neuropixels 1.0-NHP, a high-density electrode array for large-scale neural recording in nonhuman primates, enabling recording from over 3000 single neurons.

Identifying Interpretable Latent Factors with Sparse Component Analysis

This paper introduces SCA, an unsupervised method for identifying interpretable latent factors in neural data, and shows its effectiveness across different datasets.

Neural activity during a simple reaching task in macaques is counter to gating and rebound in basal ganglia-thalamic communication

The paper examines neural activity during a reaching task in macaques and finds that basal ganglia-thalamic communication does not follow standard gating or rebound models.

Generation of Rapid Sequences by Motor Cortex

This study investigates how motor cortex activity contributes to the execution of rapid motor sequences and finds that elements are not fused but executed in parallel with temporal compression.

Holding the arm still through integration of cortical commands

The paper investigates how arm holding is controlled by showing that postural fields integrate reach commands, even after corticospinal damage.

Conservation of preparatory neural events regardless of how movement is initiated

This study shows that preparatory neural events in monkeys are conserved across different movement initiation contexts, but preparation can be temporally flexible and brief.
