Monosynaptic Excitation of Alpha Motoneurones from Supraspinal Structures in the Cat

Lund, S., Pompeiano, O.·1968·Acta Physiologica Scandinavica

Abstract

The origin of descending fibres evoking monosynaptic excitatory postsynaptic potentials (EPSPs) in motoneurones was studied.Lumbar flexor and extensor motoneurones were recorded from intracellularly.The ipsilateral ventral and lateral funicles were stimulated at thoracic level in cats with and without chronic lesions of the ipsilateral cervical cord or vestibular complex.In other experiments the ipsilateral Deiters' nucleus was stimulated.Valleys in decending ipsilateral fibres evoke a monosynaptic EPSP in the majority of the flexor and extensor motoneurones with an amplitude corresponding to about 25 per cent of the homonymous group Ia EPSP.The effect is almost entirely of supraspinal origin.Most extensor motoneurones receive this action from fibres originating in the ipsilateral Deiters' nucleus.Flexor, and probably some species of extensor motoneurones, receive the action from a supraspinal structure outside the ipsilateral vestibular complex.The results are discussed in relation to the cerebellar influence on the Deiters' nucleus and the cerebellar inhibition of extensor rigidity.

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.
