Responses of the pyramidal tract to stimulation of the baboon's motor cortex

Open access
Kernell, D., Chien-Ping, Wu·1967·The Journal of Physiology

Abstract

1. The arm area of the baboon's precentral motor cortex was stimulated by brief surface‐anodal pulses, and the discharge of the corticospinal tract (the ‘pyramidal tract waves’) was recorded by an electrode resting on the dorsolateral surface of the cervical spinal cord. 2. Some properties of the pyramidal tract waves were described, and they were also studied in relation to the firing of single cortico spinal fibres. 3. The results led to the conclusion that the later pyramidal tract waves (the ‘I waves’) were almost exclusively due to a semi‐synchronous repetitive discharge of the same fast cortico spinal fibres as those responsible for the initial wave (the ‘D wave’). 4. Some problems concerning the origin and significance of the I waves were discussed.

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.
