The paper examines how stimulus polarity affects the microsaccadic rate signature, finding stronger rebound effects for small black stimuli compared to small white stimuli.

This study shows that task-irrelevant visual forms influence both covert and overt spatial selection in humans and monkeys, indicating that mid-level perceptual processes affect target selection.

This study shows that ocular position drifts are rapidly and systematically modulated by visual stimuli in macaques, with short latencies and stimulus-specific responses.

This paper introduces a deep learning algorithm to detect complex spikes in Purkinje cells, achieving expert-level accuracy with faster performance than manual inspection.

This study investigates how microsaccades affect superior colliculus neural responses by modulating visual reafferent responses based on microsaccade amplitude and direction relative to visual stimuli.

The paper shows that visual-only mechanisms in the retina account for saccadic suppression, without needing motor-based signals.

The paper investigates small-saccade triggering in rhesus macaques, finding longer reaction times for small saccades and asymmetry in upward vs. downward visually guided saccades.

This study shows humans and monkeys can voluntarily generate microsaccades on demand without visual guidance or training, with corresponding neural activity in the superior colliculus.

This study investigates how the primate superior colliculus represents foveal visual input and its role in precise eye movements.

This study shows that smooth pursuit initiation is sensitive to visual inputs during 'open-loop' intervals, with transient eye position errors affecting eye velocity and acceleration.

This paper develops a CNN that detects saccades with human-level accuracy, outperforming existing methods and aiding neurophysiological research.

This study investigates the oculomotor system's ability to track slow target motions in rhesus macaques, revealing a band-pass transfer function and directional differences in pursuit gain.

This study investigates perceptual mislocalization during upward saccades and finds directional differences in peri-saccadic perceptual alterations.

This study shows that the primate superior colliculus detects low spatial frequencies in natural scenes more rapidly and over-represents them in neural response sensitivity, aiding efficient gaze realignment.

The paper identifies visual-motor neurons in the primate superior colliculus as a key locus for saccadic suppression, showing strong spatial frequency selectivity and predictive power for behavioral suppression effects.
