Monosynaptic Reflexes (H‐Reflex) and Motoneurone Excitability in Man
Developmental Medicine & Child Neurology, 1969SUMMARYThe author reviews the rationale of neurophysiological techniques currently employed in the investigation of motor function in man. The physiological basis of monosynaptic reflexes elicited by mechanical or electrical means is critically considered; and recent evidence concerning the complexity of these evoked responses is presented.

Covariation of monosynaptic reflexes in spinal and decerebrate cats
Experimental Neurology, 1966Abstract Monosynaptic reflexes were recorded in several muscle nerves simultaneously. The mean amplitude, relative variance, and cross correlation of the reflexes was computed. A method is presented to calculate the variance and correlation of moving averages, and of the deviation of measurements from moving averages.

Reproducibility of a heteronymous monosynaptic reflex in biceps brachii
Electroencephalography and Clinical Neurophysiology/Electromyography and Motor Control, 1995The present study provides normal data for a new technique to assess conduction across the C5/C6 segments by recording a heteronymous monosynaptic reflex response from the contracting biceps brachii in response to stimulation of the median nerve in the cubital fossa.

Age-related Changes in Monosynaptic Reflex Excitability
Journal of Gerontology, 1982The excitability of the H-reflex was tested in a younger group (19 to 31 years) and an older group (60 to 72 years) of subjects. The threshold for the H-reflex was higher and the reflex latency was 7 msec longer in the older group of subjects. Also, the H-reflex amplitude was significantly smaller, longer in duration and polyphasic in shape whereas the

Modulation of cat monosynaptic reflexes by substance P
Brain Research, 1980Substance P (SP) applied by iontophoresis at different current strengths to single motoneurons of cat spinal cord did not cause these units to discharge. SP produced a gradual and prolonged change in synaptic excitability as measured by response to dorsal root stimulation. The effect outlasted application of SP.

Descending Monosynaptic and Reflex Control of γ‐Motoneurones
Acta Physiologica Scandinavica, 1969AbstractThe supraspinal and reflex control of γ‐motoneurones has been studied with intra‐ and extracellular recording from lumbosacral γ‐motoneurones in the cat. Monosynaptic EPSPs were recorded in some γ‐motoneurones on stimulation of the brain stem.

Central effects of succinylcholine and decamethonium on monosynaptic reflexes
American Journal of Physiology-Legacy Content, 1961Observations have been made in cats upon central mechanisms responsible for reduction in monosynaptic responses of triceps surae motoneurons following intravenous injection of decamethonium or succinylcholine. Two-thirds of extensor motoneurons show an increase in random firing under the influence of these drugs.

An electrophysiological investigation into the monosynaptic H-reflex in the rat
Brain Research, 1998In order to set up a non-invasive, reliable and reproducible model for investigating alpha-motoneuronal activity, we studied the electrophysiological features of a monosynaptic H-reflex in anaesthetised intact rats, anaesthetised and non-anaesthetised rats transected at the level of the obex.

Morphine and meperidine on bulbospinal inhibition of the monosynaptic reflex
European Journal of Pharmacology, 1973Abstract The effects of morphine and meperidine were studied on the ventromedial bulbospinal inhibition of the monosynaptic reflex (MRS) in decerebrate unanesthetized cats. Administration of these agents in accumulative doses (0.5–16 mg/kg, i.v.) progressively blocked this inhibition.

[Monosynaptic spinal reflex in epilepsy].
Zhurnal nevropatologii i psikhiatrii imeni S.S. Korsakova (Moscow, Russia : 1952), 1978In 33 patients with generalized convulsive seizures a monosynaptic spinal reflex was studied. In an interattack period the author observed its clear asymmetry which was combined with a contralateral situation of epileptogenic focus on the EEG. In the majority of cases in patients with diffusive paroxysmal activity on the EEG asymmetry in the quantity ...
