The paper shows that acceleration information can be directly decoded from MT neuron activity faster and more accurately than through velocity changes, while MST does not refine this representation.

The paper shows fixational eye movements in marmosets significantly contribute to neuronal variability and enhance spatial information in visual cortex.

The paper investigates how temporal weighting of sensory evidence in decision-making is shaped by interactions between sensory and decision circuits using behavioral, neural, and computational models in macaques.

This study investigates how natural gaze behavior influences V1 activity in freely moving marmosets, showing that gaze shifts and fixations modulate neural responses through distinct mechanisms.

This study analyzes 59 macaque studies to assess factors influencing choice probability, finding consistent patterns across tasks and regions with exceptions in bistable percepts and area V1.

This study demonstrates that systemic AAV delivery enables widespread calcium indicator expression in marmosets, allowing functional optical imaging of visual area MT at multiple scales.

The paper investigates running-correlated modulations in the peripheral visual cortex of marmosets, finding substantial positive effects in contrast to small suppressive effects in the foveal region.

This study shows that temporal integration is a common feature in perceptual decision-making across species, using behavioral data from monkeys, rats, and humans.

The paper measures retinal motion patterns during natural locomotion and explains how gaze location and behavior shape these patterns.

This study shows that MT area in macaques has task-related cognitive contributions distinct from motion encoding and decoding for direction discrimination.

The paper compares how running affects visual cortex activity in marmosets and mice, finding smaller and suppressive modulations in marmosets compared to mice.

The paper introduces a system for combining electrophysiology data across multiple sessions in marmosets to enable long-term neural recordings and analysis.

The paper analyzes neural activity in primate MT cortex during perceptual decision-making and finds that choice-related signals are misaligned with stimulus encoding, suggesting feedback from downstream areas.

The paper compares discrete stepping and nonlinear ramping dynamics in LIP neuron spiking responses during decision-making and finds that stepping dynamics better describe most neurons, though an extended ramping model accounts for a similar fraction.

The paper responds to criticisms of previous findings on LIP neuron dynamics by reanalyzing data with lower bounds and showing the stepping model still better explains spike trains in many cases.
