Distinct neural geometries for target position and velocity in the primate superior colliculus

The paper investigates how the primate superior colliculus represents target velocity and position, finding distinct neural geometries for each.

Drifting population dynamics with transient resets characterize sensorimotor transformation in the monkey superior colliculus

The paper analyzes neural activity in the superior colliculus of monkeys during a saccade task, identifying dynamics of sensorimotor transformation through a novel measure called the Visuomotor Proximity Index.

Investigating the mechanisms underlying saccade generation in the frontal eye fields using multi-site microstimulation

This study investigates how population activity in the frontal eye field (FEF) is integrated to generate saccadic eye movements using multi-site microstimulation in monkeys.

Euclidean Distance based Adaptive Sampling Algorithm for Disassociating Transient and Oscillatory Components of Signals

This paper introduces an adaptive smoothing algorithm to separate transient and oscillatory components in neural signals, showing improved performance on synthetic and recorded data.

Population Temporal Structure Supplements The Rate Code During Sensorimotor Transformations

The paper proposes that movement initiation is governed by population temporal structure rather than firing rate alone, using recordings and microstimulation in the superior colliculus and frontal eye fields.

Time-course of population activity along the dorsoventral extent of the superior colliculus during delayed saccade tasks

The paper examines population activity in the superior colliculus during delayed saccade tasks, revealing a spatiotemporal organization of neural activity along the dorsoventral axis.

Instantaneous midbrain control of saccade kinematics

This study investigates whether the superior colliculus uses a dynamic rate code to control saccade kinematics, finding a strong correlation between SC activity and instantaneous eye velocity.

The Superior Colliculus And The Steering Of Saccades Toward A Moving Visual Target

This study investigates how superior colliculus neurons encode target motion during saccades, finding that their movement fields shift in the direction of target motion but not for future locations.

Removal Of Inhibition Uncovers Latent Movement Potential During Preparation

The paper investigates preparatory neural activity in the superior colliculus and finds that latent movement commands exist before saccades, challenging threshold-based models of movement initiation.

Extracting Saccades From Eye Movements Triggered By Reflex Blinks

The paper develops a mathematical method to extract saccade features from blink-triggered eye movements, showing that saccades can be modeled as a delayed combination of a blink-related movement and a normal saccade.
