The possible pathways mediating the inhibitory influences of two types of presynaptic metabotropic receptors – group III metabotropic glutamate receptors (mGluRIII) and GABAB receptors (GABABR) – on miniature glycinergic activity in motoneurons i

Structuro-functional correlations in the organization of connections between primary afferent fibers and motoneurons were investigated in the lumbar segments of spinal cord from 1–2-week-old rats. A single afferent fiber collateral was found to mak

Intracellular investigations into interaction between lumbar motoneurons were made during ventral root stimulation in spinal cord isolated from 9 to 14-day-old rats and horseradish peroxidase injection. It was found that electronic interaction is bro

The structure of connections between lumbar motoneurons was investigated in preparations of spinal cord isolated from young rats. This involved applying horseradish peroxidase to the ventral root and intracellular injection of the same enzyme into mo

1. All investigated mesencephalic structures have definite synaptic influences on spinal α-motoneurons. The red nucleus facilitates flexor and inhibits extensor motoneurons. The substantia nigra acts in the same way as the red nucleus on motoneurons

Intracellular recording and computer averaging used in experiments on monkeys (Macaca rhesus) showed that fast-conducting reticulo- and vestibulospinal fibers form monosynaptic excitatory connections with lumbar α-motoneurons. Monosynaptic bulbo spi

Postsynaptic potentials evoked by stimulation of the motor cortex or pyramids before and after acute pyramidotomy were investigated in the lumbar motoneurons of monkeys. In response to activation of fibers of the pyramidal tract monosynaptic EPSPs pr
