Sentence examples for descending drive from inspiring English sources

Further, shell removal did not appreciably alter head/neck/spine flexion, and these inputs might act to reduce descending drive to spinal motor networks during foot-free as well as control experiments.

They interpreted this finding as indicating that a greater proportion of the descending drive to motor neurons came from reticulospinal pathways via propriospinal interneurons.

The common view is that spastic dystonia is an efferent phenomenon, mediated by an abnormal pattern of supraspinal descending drive [ 18].

It may also have stemmed from a failure in descending drive (ie, insufficient motor unit firing rate) to compensate for a hyperthermia-induced increase in muscle relaxation rate.

The reduced EMG and V-wave responses to muscle fibers in the paretic limb we observed are caused to a large extent by reduced descending drive from supraspinal centers, and probably increased recurrent inhibition (Garland et al. 2009).

However, surface EMG and twitch interpolation techniques do not quantify the descending drive to the lower motoneurons nor do they take into account the source of this drive (De Haan et al. 2009).

It is proposed that ascending stimulus driven and descending context driven pathways combine in an iterative manner to produce an accurate visual experience of our surroundings [ 1, 2].

Cervical spinal cord injury (SCI) interrupts descending neural drive to phrenic motoneurons causing diaphragm muscle (DIAm) paralysis.

However, sEMG signals lack sensitivity to detect changes in the number and discharge rate of active motor units that would indicate increased central motor output [108, 109] and therefore may not be sensitive enough to accurately determine whether or not altering pH may affect descending central drive.

A more recent body of literature suggests a relationship between increasing levels of intramuscular metabolite concentrations analogous with high rates of skeletal muscle contraction, and greater group II I/IVafferent firing in humans [110 112], which would ultimately act as a protective mechanism against peripheral fatigue by limiting descending central drive [113].

The findings may also reflect the relatively minor role afferent feedback may play in these situations of extreme peripheral fatigue, where other factors separate to group III and IV afferents may have contributed to the down-regulation of descending central drive.
