  • spinal
  • The interneuronally mediated reflex actions evoked by electrical stimulation of group II muscle afferents in low spinal cats have been reinvestigated with intracellular recording from motoneurones to knee flexors and ankle extensors. (springer.com)
  • It is proposed that the group II actions of the flexor reflex pattern characterizing the anaesthetized low spinal cat are due to suppression of the inhibitory pathway to flexor motoneurones and the excitatory pathway to extensor motoneurones. (springer.com)
  • This suggests that afferent information, from the vagus nerves (and possibly the spinal cord) may be important in preventing apneusis. (lsuhsc.edu)
  • Like the pathways for pain and temperature, the message is relayed to the spinal cord, then crosses the midline and ascends via the lateral spinothalamic tract to the thalamus, and then finally travels to the cerebral cortex. (skintherapyletter.com)
  • inhibition
  • It is postulated that these group II EPSPs are mediated by an interneuronal pathway from the FRA which also supply interneuronal pathways giving inhibition to extensor or/and flexor motoneurones and excitation to flexors as postulated by Eccles and Lundberg (1959) and Holmqvist and Lundberg (1961).

  • Their role in visceral pain remains to be determined, but they have shown promise in inhibition of the triggering of gastro-esophageal reflux, via an action on mechanosensory gastric afferents. (frontiersin.org)
  • Presynaptic inhibition of tooth pulp afferents in the trigeminal nucleus during REM sleep. (biomedsearch.com)
  • In order to find whether presynaptic inhibition of tooth pulp afferents is enhanced in any phase of sleep or wakefulness, the orthodromic mass response of the trigeminal nucleus to electrical stimulation of the ipsilateral tooth pulp and the antidromic mass response of the tooth pulp to stimulation of the trigeminal nucleus were recorded in the cat.

  • Transient inhibition of TrkB around the time of weak TBS to the second pathway diminished L-LTP in that pathway without affecting the first one. (jneurosci.org)
  • reflexes
  • These results demonstrate the important role of Kv1.1 in afferent chemosensory activity and suggest that mutations in the human Kv1.1 gene have functional consequences during stress responses that involve respiratory reflexes. (jneurosci.org)
  • limb
  • Immunohistochemical studies demonstrated Kv1.1 in the afferent limb of the carotid body chemoreflex (the major regulator in the response to hypoxia), consisting of the carotid body, petrosal ganglion, and nucleus of the solitary tract (NTS). (jneurosci.org)
  • Appelberg B, Hulliger M, Johansson H, Sojka P (1983) Actions on γ-motoneurones elicited by electrical stimulation of group II muscle afferent fibres in the hind limb of the cat. (springer.com)
  • tracts
  • The appearance of some axons exiting the main fiber tracts and exhibiting expanded growth cones suggests that afferent fiber extension was still underway [ILLUSTRATION FOR FIGURE 1I OMITTED]. (thefreedictionary.com)
  • suggests
  • The location of the DRG within this tract suggests that the DRG may function to integrate afferent information for the control of breathing. (lsuhsc.edu)
  • functional
  • The objective of this study was to identify potential structural and functional alterations in the afferent visual system in HNPP patients. (mdc-berlin.de)
  • CONCLUSION: PMP22 deletion leads to functional, metabolic and macro-structural alterations in the afferent visual system of HNPP patients. (mdc-berlin.de)
  • central
  • Efferent visual pathway lesions in the central nervous system (CNS) may create a perception of oscillopsia, a visual disturbance in which objects appear to jiggle or move owing to nystagmus (involuntary eye movements). (medscape.com)
  • visual
  • Optic neuritis is an inflammatory injury of the optic nerve that causes vision loss, which is common in MS. Some individuals with MS also experience homonymous visual field defects caused by lesions in retrochiasmal or retrogeniculate regions of the afferent visual pathway. (medscape.com)
  • Afferent visual pathway affection in patients with PMP22 deletion-related hereditary neuropathy with liability to pressure palsies. (mdc-berlin.de)
  • activity
  • The afferent activity of this chemosensory pathway is initiated at oxygen-sensitive cells in the carotid body that lies in the bifurcation of the common carotid artery. (jneurosci.org)
