Rotational dynamics in motor cortex are consistent with a feedback controller
Recent studies have identified rotational dynamics in motor cortex (MC), which many
assume arise from intrinsic connections in MC. However, behavioral and neurophysiological …

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

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

Contextual cues are not unique for motor learning: Task-dependant switching of feedback controllers
J Česonis, DW Franklin - PLOS Computational Biology, 2022 - journals.plos.org
The separation of distinct motor memories by contextual cues is a well known and well
studied phenomenon of feedforward human motor control. However, there is no clear …
