Dissociable effects of feature expectation on saccades and presaccadic perception

The paper investigates how feature expectation affects saccades and presaccadic perception, finding dissociable effects on sensitivity and saccade latency.

Presaccadic modulation of lateral interactions

This study shows that saccade preparation modulates lateral interactions in visual processing, increasing suppression of targets at larger flanker distances during presaccadic periods.

Presaccadic attentional shifts are not modulated by saccade amplitude

This study investigates whether presaccadic perceptual enhancement varies with saccade amplitude and finds it does not.

Performance modulations phase-locked to action depend on internal state

The paper investigates action-related modulations of perceptual performance and finds that these modulations depend on internal states like attention and decision criteria, specifically at ~17 Hz.

Quantifying rhythmicity in perceptual reports

The paper compares methods for quantifying rhythmicity in perceptual reports using simulated data and evaluates their sensitivity, specificity, and D-prime.

Visual neuroscience methods for marmosets: efficient receptive field mapping and head-free eye tracking

This paper develops methods for visual neuroscience in marmosets, enabling head-free eye tracking and efficient receptive field mapping without moving stimuli.

Gamma synchronization between V1 and V4 improves behavioral performance

The paper shows that gamma synchronization between V1 and V4 in macaques predicts reaction times and improves behavioral performance through optimal phase relations.

Temporal anticipation based on memory

This study shows that long-term memories guide attention dynamically based on learned temporal associations, enhancing target detection and discrimination when timing matches learned contingencies.
