Species-specific oculomotor control tolerances explain saccadic suppression strength differences between macaques and zebrafish

The paper compares saccadic suppression strength between macaques and zebrafish, showing it reflects differences in sensory and motor noise levels and computational resource allocation.

Microsaccadic eye movement generation is sufficient to enhance peripheral visual sensitivity

This study shows that generating microsaccadic eye movements can enhance peripheral visual sensitivity independently of attentional demands.

Sound unmasks short-latency tectal visual signals that are independent of the primary visual cortex

The paper shows that short-latency visual signals in primates can bypass the primary visual cortex when combined with auditory stimuli, affecting saccadic eye movements.

Much stronger coarse-to-fine visual processing in primate superior colliculus than primary visual cortex neurons

This study compares coarse-to-fine visual processing dynamics in primate superior colliculus and primary visual cortex, finding stronger dynamics in the SC.

Much higher covariation with foveation timing by superior colliculus than primary visual cortical neuronal activity

The paper compares covariation between superior colliculus and primary visual cortical activity with eye movement timing, finding stronger covariation in the superior colliculus.

Transient focal inactivation of the primary visual cortex abolishes saccadic inhibition

This study shows that transient inactivation of the primary visual cortex eliminates visually-driven saccadic inhibition, highlighting the dominance of the geniculostriate pathway in this reflex.

Vision dominates sound in mediating classic cue-induced microsaccadic eye movement modulations in rhesus macaque monkeys

This study investigates how visual and auditory stimuli modulate microsaccadic eye movements in rhesus macaques, finding that vision has a stronger influence than sound on microsaccadic inhibition.

Two-dimensional perisaccadic visual mislocalization in rhesus macaque monkeys

This paper establishes a two-dimensional perisaccadic visual mislocalization paradigm in rhesus macaques, showing similar mislocalization patterns to humans.

Perisaccadic perceptual mislocalization strength depends on the visual appearance of saccade targets

This study shows that perisaccadic perceptual mislocalization strength depends on the visual appearance of saccade targets, suggesting corollary discharge conveys more than just spatial vectors.

Microsaccadic suppression of peripheral perceptual detection performance as a function of foveated visual image appearance

The paper investigates how microsaccadic suppression affects peripheral perceptual detection performance across different visual backgrounds.

Visual feature tuning properties of short-latency stimulus-driven ocular position drift responses during gaze fixation

The paper investigates short-latency visual stimulus-driven ocular drift responses during gaze fixation, finding they are feature-tuned and synchronized with saccadic inhibition.

Visual feature tuning properties of stimulus-driven saccadic inhibition in macaque monkeys

The paper investigates how saccadic inhibition in macaque monkeys is tuned to various visual features, finding systematic dependencies on stimulus size, spatial frequency, contrast, motion direction, and speed.

Sensory tuning in neuronal movement commands

This study shows that neuronal eye movement commands in the superior colliculus include a sensory representation of visual targets, with stronger feature discrimination than visual responses.

Superior colliculus saccade motor bursts do not dictate movement kinematics

This study shows that saccade-related bursts in the primate superior colliculus do not determine movement kinematics, as burst strength varies with visual field direction and target visibility without affecting kinematics.

Faster detection of "darks" than "brights" by monkey superior colliculus neurons

This study shows that monkey superior colliculus neurons detect dark stimuli faster than bright stimuli, even if they are less sensitive to darks.

Suppression without inhibition: How retinal computation contributes to saccadic suppression

The paper identifies three retinal mechanisms underlying saccadic suppression in mice, pigs, and macaques using electrophysiology and modeling, showing suppression arises from temporal filtering and nonlinearities rather than inhibition.

Dependence of perceptual saccadic suppression on peri-saccadic image flow properties and luminance contrast polarity

This study investigates how perceptual saccadic suppression depends on image flow properties and luminance contrast polarity during saccades.

Perceptual saccadic suppression starts in the retina

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