A modular neural circuit for computing the motion of objects

The paper identifies a modular neural circuit in macaque visual cortex that computes object motion by integrating component edge signals into pattern motion representations.

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.

Functional Connections Among Neurons within Single Columns of Macaque V1

The paper uses high-density recordings to analyze functional connections between neurons in macaque V1, revealing systematic variations in connection strength and synchrony based on vertical distance and stimulus tuning.

Rapid Selectivity to Natural Images Across Layers of Primate V1

This study shows that V1 neurons in macaques rapidly and strongly respond to natural images across all cortical layers within 60 ms of stimulus onset.

Heterogeneity of Neuronal Populations Within Columns of Primate V1 Revealed by High-Density Recordings

The paper uses high-density recordings to show that layer 4C neurons in primate V1 provide better orientation discrimination than other layers within the same cortical column.

Robust Encoding of Abstract Rules by Distinct Neuronal Populations in Primate Visual Cortex

The paper shows that abstract rules are encoded by neurons in primate visual cortex without sensory input, with rule information strongest in neurons with low visual activity and weak local network coupling.
