Scholarly Works - Preprints

Selective encoding of priors for flexible categorization but not Bayesian inference in the frontal eye field.

Preprint · April 20, 2026 Expectations or prior beliefs about the world have been shown to modulate sensory processing both at the behavioral and neural levels. Bayesian models predict that such priors compensate for input uncertainty to optimize sensory judgments. Although Bayesia ... Full text Link to item Cite

Circuits and Mechanisms for TMS-Induced Corticospinal Waves: Connecting Sensitivity Analysis to the Network Graph

Preprint · 2024 ABSTRACT Transcranial magnetic stimulation (TMS) is a non-invasive, FDA-cleared treatment for neuropsychiatric disorders with broad potential for new applications, but the neural circuits that are engaged during TMS are still poorly understood. R ... Full text Cite

Direct comparison of epifluorescence and immunostaining for assessing viral mediated gene expression in the primate brain

Preprint · October 7, 2022 ABSTRACTViral vector technologies are commonly used in neuroscience research to understand and manipulate neural circuits, but successful applications of these technologies in non-human primate models have ... Full text Cite

Contributions of Bayesian and Discriminative Models to Active Visual Perception across Saccades

Preprint · 2022 Summary The brain interprets sensory inputs to guide behavior, but behavior disrupts sensory inputs. In primates, saccadic eye movements displace visual images on the retina and yet the brain perceives visual stability, a process called active vi ... Full text Cite
