Evidence for strong synaptic coupling between single tactile afferents from the sole of the foot and motoneurons supplying leg muscles.
It has been known for some time that populations of cutaneous and muscle afferents can provide short-latency facilitation of motoneuron pools. Recently, it has been shown that the input from individual low-threshold mechanoreceptors in the glabrous skin of the hand can modulate ongoing activity in muscles acting on the fingers via spinally mediated pathways. We have extended this work to examin...
متن کاملThe effect of cutaneous mechanical stimulations of lateral plantar surface on the excitability of ipsilateral and contralateral motoneurons
Mechanoreceptors of foot sole likely contribute in the reflex regulations. Stimulation of these receptors in the lateral aspect of the foot is corresponded to the lateral plantar division of the tibial nerve. Therefore, it was hypothesized that repetitive low threshold afferents stimulation would have an inhibitory effect on the soleus H-reflexes. Methods: Sixteen normal subjects voluntarily...
متن کاملSingle low-threshold afferents innervating the skin of the human foot modulate ongoing muscle activity in the upper limbs.
We have shown for the first time that single cutaneous afferents in the foot dorsum have significant reflex coupling to motoneurons supplying muscles in the upper limb, particularly posterior deltoid and triceps brachii. These observations strengthen what we know from whole nerve stimulation, that skin on the foot and ankle can contribute to the modulation of interlimb muscles in distant innerv...
متن کاملThe effect of pinna reflex and dynamic stretch on spike discharge of single ?-axons and spindle afferents in caudal muscle spindles in rat
The ?-axons supplying muscle spindle (MS) induce a particular pattern of activity in spindle Ia and II afferents on contraction. From a dynamic viewpoint, the Ia shows increasing spike rates, but II-afferents do not show any activity. For evaluation of nerve fiber activity, spike amplitude (SA) is suggested to measure it as well as its benefit of diagnosing clinical symptoms. This paper aims to...
