Diurnal rhythm in the spinal stretch reflex
Brain Research, 1982We studied primate spinal stretch reflex (SSR) amplitude as a function of time of day. SSR amplitude was greatest around midnight and smallest around noon. The diurnal rhythm was not simply a function of number of trials, or of the lighting cycle. This rhythm offers an opportunity to study the neuronal and synaptic mechanisms producing a diurnal change

Spinal mechanisms of the functional stretch reflex
Experimental Brain Research, 1978A sudden and rapid angular displacement of the limb evokes, in human and monkey subjects, a segmented pattern of electromyographic activity in muscles which are stretched. While the first segment is acknowledged to represent a tendon jerk, it has been proposed that the second segment, occurring with a shorter latency than a reaction time, is mediated ...

The human stretch reflex and the motor cortex
Trends in Neurosciences, 1991The spinal stretch reflex, exemplified by the tendon jerk, appears to be less important in humans than a delayed 'long-latency' response. This is easily observed when muscles of the hand are stretched while they are already contracting voluntarily. On limited evidence, many have long held that the delayed response is a transcortical reflex and have ...

Phasic stretch reflex of the abdominal muscles
Experimental Neurology, 1986This analysis of the abdominal stretch reflex (ASR) evoked by a tap to the abdomen was designed to explore how abdominal motoneurons process signals from respiratory and nonrespiratory sources. We recorded surface EMGs from the external and internal oblique muscles in standing subjects. Amplitudes of the abdominal stretch reflex varied despite constant

Let us examine the lowest motor control level for which the neural structure is delimited by the major identified neurons of the spinal cord (i.e., α- and γ-motoneurons, Ia interneurons, and Renshaw cells) and by extrafusal and intrafusal muscle fibers.

Taurine Enhances Stretch Reflex Excitability
2019The purpose of this study was to characterize the effects of taurine (supplementation and acute injection) on the stretch reflex in the ankle muscles, and in particular to compare the effects of chronic taurine supplementation versus acute injection on the muscle tension, amplitude of electromyogram and velocity of muscle response.

Role of the stretch reflex in oxotremorine tremor
Life Sciences, 1996Although the basic mechanism for parkinsonian tremor is known to be central, the case for the oscillator(s) of physiological tremor and shivering is still a matter of dispute. In this case, an important role has been proposed for muscle afferents. Oxotremorine tremor has in common with shivering its frequency range (10-28 Hz) and the co-contraction of ...
