Patterns of cortical projection to hindlimb muscle motoneurone pools

摘要: Summary This study was undertaken to examine the organization of hindlimb area motor cortex. Two specific questions were posed. The first was: are cortical neurones which control excitability a given motoneurone pool localized in small zone cortex or they diffuse? second question does microstimulation activate spinal motoneurones reciprocal fashion, i.e. , is cortically elicited facilitation amuscle accompanied by inhibition antagonist? Intracortical used condition monosynaptic reflexes cat organnization projection lumbar pools. Cortical produced reflex within Facilitatory and inhibitory effective zones found have similar shape size. individual without eliciting effects on antagonists. pyramidal tract shown play an important role mediation facilition as well cord.
