Hypnic Reflex: A Spinal Perspective

Hypnic jerks are spontaneous sudden jerking movements most often occurring just prior to falling asleep [1]. They are considered non-periodic and myoclonic in behaviour and are similar to fasciculation with polysomnography. They are more probable with fatigue and sleep deprivation [2,3]. These sudden movements are common but to date still not well understood. Approximately seventy percent of th...

H reflex and spinal excitability: methodological considerations.

The Hoffmann reflex has been the tool most commonly used in exercise studies to investigate modulations in spinal excitability. However, the evolution of electromyographic responses with the increase in stimulation intensity has rarely been assessed when the muscle is active. The purpose of this study was thus to identify that part of the recruitment curve at which the investigation of the Hoff...

Reflex activity in chronic spinal cats.

Reflex activity of spinal mammals have been investigated mostly in acute spinal cats, or in chronic cats and dogs spinalized in the early postnatal stage and tested after various periods (Grayson and Mc Couch 1947, Shurrager and Dykman 1951, Kozak et al. 1962). The amount of data, concerning 'adult chronic spinal preparations, i.e. operated when the spinal cord has reached maturity, is very sca...
