Spatiotemporal transformations for gaze control

A Sajad, M Sadeh, JD Crawford - Physiological reports, 2020 - Wiley Online Library
Sensorimotor transformations require spatiotemporal coordination of signals, that is, through
both time and space. For example, the gaze control system employs signals that are time …

Integration of landmark and saccade target signals in macaque frontal cortex visual responses

A Schütz, V Bharmauria, X Yan, H Wang… - Communications …, 2023 - nature.com

codes for action is poorly understood. Here, we test landmark influence on the visual …

Multiunit frontal eye field activity codes the visuomotor transformation, but not gaze prediction or retrospective target memory, in a delayed saccade task

S Seo, V Bharmauria, A Schütz, X Yan, H Wang… - eneuro, 2024 - eneuro.org
Single-unit (SU) activity—action potentials isolated from one neuron—has traditionally been

Laminar architecture of visual responses in supplementary eye field of macaques

P Thirunavukkarasu, SP Errington, A Sajad, JD Schall - bioRxiv, 2023 - biorxiv.org
Previously, we have described the laminar organization of neurons in the supplementary
eye field (SEF) that signal error, reward gain and loss, conflict, event timing, and goal …

Instruction Alters The Influence Of Allocentric Landmarks In A Reach Task

L Musa, X Yan, JD Crawford - bioRxiv, 2024 - biorxiv.org
Allocentric landmarks have an implicit influence on aiming movements, but it is not clear
how an explicit instruction (to aim relative to a landmark) influences reach accuracy and …

Neural Population Dynamics of Sensorimotor Signals for Eye Movements

MR Heusser - 2022 - search.proquest.com
During active vision, we convert information about visual objects in our periphery into goal-
directed eye movements known as saccades. This process of sensorimotor integration is …
