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.

Live Spike Sorting of Large-scale Neural Recordings

This paper introduces a live spike sorting system that achieves performance comparable to offline sorting and enables closed-loop interventions in neural recordings.

Dependence of Contextual Modulation in Macaque V1 on Interlaminar Signal Flow

The paper shows that in macaque V1, border ownership modulation depends on interlaminar signal flow, with stronger modulation when feedback/horizontal layers contribute more to input layers.

Contribution of statistical learning to learning from reward feedback

The paper shows that environmental regularities can bias reward learning by increasing confirmation bias and reducing the dimensionality of learning tasks.

Training-dependent gradients of timescales of neural dynamics in the primate prefrontal cortex and their contributions to working memory

This study examines how training affects timescales of neural dynamics in primate prefrontal cortex and their role in working memory.

Cue-specific neuronal ensembles span intermittent rate coding of working memory

The paper shows that mnemonic information alternates between On and Off periods in prefrontal neurons during memory delays, coexisting with activity-silent mechanisms.

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.

Novel entropy-based metrics for predicting choice behavior based on local response to reward

The paper introduces entropy-based metrics to predict choice behavior in mice and monkeys, explaining 50% and 41% of matching variance, and develops a more accurate model based on these metrics.
