The paper uses computational models of cortical circuits to investigate the mechanisms behind D- and I-wave responses to cortical stimulation, finding consistent patterns across different cortical regions.

The paper investigates how neurons in the frontal eye field encode priors for visual stability judgments, finding that they support flexible categorization rather than Bayesian inference.

This paper introduces a high-throughput method for studying retinal ganglion cell projections, physiology, and morphology across species without relying on genetically modified animals.

This study uses retrograde optogenetics in macaques to show that FEF outputs to the superior colliculus are diverse but predominantly motor-related, supporting a visuomotor convergence model.

The paper develops a computational model of motor cortex using human recordings to analyze TMS-induced corticospinal waves and identifies key neural pathways and mechanisms.

The paper compares epifluorescence, immunofluorescence, and immunohistochemistry for assessing viral-mediated gene expression in macaques, finding that the latter two methods detect more transduced neurons and provide better visualization.

The paper investigates whether active visual perception during saccades follows Bayesian principles, finding that subjects use Bayesian models for continuous judgments and discriminative models for categorical judgments based on uncertainty sources.

This study uses concurrent fMRI and TMS to show that increasing TMS intensity alters functional connectivity between visual and non-visual networks, affecting motion discrimination performance.

The paper examines how visual and auditory signals are represented in three brain areas during saccade tasks, finding that both modalities use hybrid reference frames that evolve over time.

This study investigates how different intensities and timings of TMS affect visual perception and brain activity, finding that lower intensities can enhance performance.

This study applies long-interval paired-pulse TMS to motion-sensitive visual cortex but finds no changes in motion perception.

This study investigates how task properties influence the balance between model-based and model-free learning strategies in decision-making tasks.

The paper examines how visual receptive fields shift across fixation positions in three brain regions, finding stable representations only in the superior colliculus.
