Express visuomotor responses reflect knowledge of both target locations and contextual rules during reaches of different amplitudes

S Contemori, GE Loeb, BD Corneil… - Journal of …, 2023 - Soc Neuroscience
When humans reach to visual targets, extremely rapid (∼ 90 ms) target-directed responses
can be observed in task-relevant proximal muscles. Such express visuomotor responses are …

Symbolic cues enhance express visuomotor responses in human arm muscles at the motor planning rather than the visuospatial processing stage

S Contemori, GE Loeb, BD Corneil… - Journal of …, 2022 - journals.physiology.org
Humans can produce “express”(∼ 100 ms) arm muscle responses that are inflexibly locked
in time and space to visual target presentations, consistent with subcortical visuomotor …

High-contrast, moving targets in an emerging target paradigm promote fast visuomotor responses during visually guided reaching

RA Kozak, BD Corneil - Journal of Neurophysiology, 2021 - journals.physiology.org
Humans have a remarkable capacity to rapidly interact with the surrounding environment,
often by transforming visual input into motor output on a moment-to-moment basis. But what …

Express arm responses appear bilaterally on upper-limb muscles in an arm choice reaching task

SL Kearsley, AL Cecala, RA Kozak… - Journal of …, 2022 - journals.physiology.org
When required, humans can generate very short latency reaches toward visual targets, such
as catching a falling cellphone. During such rapid reaches, express arm responses are the …

The influence of temporal predictability on express visuomotor responses

S Contemori, GE Loeb, BD Corneil… - Journal of …, 2021 - journals.physiology.org
Humans are able to generate target-directed visuomotor responses in less than 100 ms after
stimulus onset. These “express” responses have been termed stimulus-locked responses …

An emerging target paradigm evokes fast visuomotor responses on human upper limb muscles

RA Kozak, AL Cecala, BD Corneil - BioRxiv, 2020 - biorxiv.org
To reach towards a seen object, visual information has to be transformed into motor
commands. Visual information such as the object's colour, shape, and size is processed and …

[HTML][HTML] Evidence for an intricate relationship between express visuomotor responses, postural control and rapid step initiation in the lower limbs

LS Billen, BD Corneil, V Weerdesteyn - Neuroscience, 2023 - Elsevier
Recent work has described express visuomotor responses (EVRs) on the upper limb. EVRs
are directionally-tuned bursts of muscle activity that occur within 100 ms of visual stimulus …

Trial-by-trial modulation of express visuomotor responses induced by symbolic or barely detectable cues

S Contemori, GE Loeb, BD Corneil… - Journal of …, 2021 - journals.physiology.org
Human cerebral cortex can produce visuomotor responses that are modulated by contextual
and task-specific constraints. However, the distributed cortical network for visuomotor …

Convergence of proprioceptive and visual feedback on neurons in primary motor cortex

KP Cross, DJ Cook, SH Scott - BioRxiv, 2021 - biorxiv.org
An important aspect of motor function is our ability to rapidly generate goal-directed
corrections for disturbances to the limb or behavioural goal. Primary motor cortex (M1) is a …

Towards a unified neural mechanism for reactive adaptive behaviour

G Novembre, GD Iannetti - Progress in neurobiology, 2021 - Elsevier
Surviving in natural environments requires animals to sense sudden events and swiftly
adapt behaviour accordingly. The study of such Reactive Adaptive Behaviour (RAB) has …
