Neural Control of Voluntary Movement Initiation

Hanes, Doug P., Schall, Jeffrey D.·1996·Science

Abstract

When humans respond to sensory stimulation, their reaction times tend to be long and variable relative to neural transduction and transmission times. The neural processes responsible for the duration and variability of reaction times are not understood. Single-cell recordings in a motor area of the cerebral cortex in behaving rhesus monkeys ( Macaca mulatta ) were used to evaluate two alternative mathematical models of the processes that underlie reaction times. Movements were initiated if and only if the neural activity reached a specific and constant threshold activation level. Stochastic variability in the rate at which neural activity grew toward that threshold resulted in the distribution of reaction times. This finding elucidates a specific link between motor behavior and activation of neurons in the cerebral cortex.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The process suggests an accumulation of information toward a threshold, consistent with models of reaction time proposed by other investigators.

    “The process suggests an accumulation of information toward a threshold, consistent with models of reaction time proposed by other investigators”
  • The variability inherent in this estimate is consistent with the observation that neurons in other brain structures exhibit a more consistent relationship with saccade initiation.

    “The variability inherent in this estimate is consistent with the observation that neurons in other brain structures exhibit a more consistent relationship with saccade initiation”
  • Variation in the buildup rate affects the amount of time it takes to reach a decision.

    “variation in the buildup rate also affects the amount of time it takes to reach a decision (19–21, 37, 38)”
  • On a variety of 2-choice decision tasks, a threshold crossing is associated with termination of the decision.

    “On a variety of 2-choice decision tasks, a threshold crossing is associated with termination of the decision 1,2,19.”

  • FEF and SC are brain regions essential for selecting, preparing, and initiating saccadic eye movements.

    “In the case of oculomotor tasks, a natural candidate is movement neurons in the frontal eye field (FEF) and superior colliculus (SC), which are brain regions essential for selecting, preparing, and initiating saccadic eye movements.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
