A trigeminal monosynaptic reflex in birds
Experimental Neurology, 1967Abstract A trigeminal monosynaptic “masticatory” stretch reflex was found in ducks. The trigeminal unipolar neurons located in the posterior commissure represent its afferent limb. Their process has a peripheral branch connected with the spindles contained in the “masticatory” muscles, while the central branch synapses with the motoneurons of the ...

A trigeminal monosynaptic reflex in reptilia
Experimental Neurology, 1971Abstract The masseterine reflex has been investigated in Caiman sclerops . Electrical stimulation of the trigeminal mesencephalic nucleus induced in the ipsilateral mandibular branch of the nerve a response which consisted of two waves. The first one, s, with a short latency, represented the spread of the stimulus along the afferent proprioceptive ...

Tenotomy and the spinal monosynaptic reflex
Experimental Neurology, 1970Abstract Monosynaptic reflexes from lumbosacral segments of the cat spinal cord have been measured 1–7 weeks after unilateral tenotomy of hind-limb muscles. Previous findings of increased reflexes from stimulation of nerves from tenotomized muscles have been confirmed.

Monosynaptic reflex and natural sleep
Experientia, 1964Le reflexe monosynaptique (MSR) du nerf tibial ou du peronier a ete observe chez le chat intact en experiences chroniques et non-anesthesie au cours des deux differentes phases du sommeil; la phase de hautvoltage ou des fuseaux et la phase paradoxale de basvoltage.

Hypoxia and monosynaptic reflexes in humans
Journal of Applied Physiology, 1987The recruitment curves of the monosynaptic Hoffmann (H) reflex and of the direct motor (M) excitation of alpha-motor fibers of the posterior popliteal nerve were studied in seven human subjects in normoxic and hypoxic conditions at sea level. The amplitude of the H and M responses were determined from the computerized full-wave rectified and ...

Parkinsonism: Electromyographic Studies of Monosynaptic Reflex
Science, 1965Electromyographic studies of the monosynaptic reflex in 70 Parkinsonian patients and 12 normal subjects show four types of abnormal facilitation and recovery curves in the Parkinsonian group, types that correspond to variations in the clinical syndrome; Cryosurgical lesions in the ventro-lateral and ventro-postero-lateral nuclei of the thalamus restore

Development of the monosynaptic stretch reflex circuit
Current Opinion in Neurobiology, 2003Significant advances have been made during the past few years in our understanding of how the spinal monosynaptic reflex develops. Transcription factors in the Neurogenin, Runt, ETS, and LIM families control sequential steps of the specification of various subtypes of dorsal root ganglia sensory neurons. The initiation of muscle spindle differentiation

Effect of tetanus toxin on the monosynaptic reflex
Naunyn-Schmiedeberg's Archives of Pharmacology, 1983Tetanus toxin was injected at various doses (0.1-10,000 mouse MLD/kg) into the gastrocnemius muscle of the left hind leg of the cat. The relative excitability of the monosynaptic reflex (MSR) was increased in the very early period of the intoxication decreased in the later period, during which the MSR of the gastrocnemius was either partially or ...

Pain effect on monosynaptic and polysynaptic reflex inhibition
Archives of Physical Medicine and Rehabilitation, 1995Determine the electrophysiological effects of anterior knee pain using monosynaptic and polysynaptic reflexes.A pretest/posttest control group experimental design with repeated measures.All tests were performed in a university laboratory.Six subjects suffering from patello-femoral dysfunction (PFD) composed the experimental group.

Orientation-induced artifacts in the measurement of monosynaptic reflexes
Neuroscience Letters, 1984Hoffmann and tendon jerk reflexes were tested in human subjects at various orientations between vertical, prone and supine. The data suggest that artifacts due to movement of soft tissue may explain the current disagreement in the literature on otolithic influences on these reflexes.
