“…It is known that cells in the gracile nucleus (Williams, BeMent, Yin & McCall, 1973) and somatosensory thalamus (Yin & Williams, 1976) respond to movements of the knee joint after surrounding skin and muscle have been denervated; these responses are almost entirely rapidly adapting. This is consistent with the finding that the few knee joint afferents which reach the dorsal column nuclei are rapidly adapting (Burgess & Clark, 1969). It appears that slowly adapting knee joint afferents make synaptic contact with cells of Clarke's column (Lindstr6m & Takata, 1972) and project via the dorsal spinocerebellar tract and its collaterals to nucleus z, just rostral to the gracile nucleus -although cells in nucleus z which receive joint input do not appear to relay to the ventrobasal thalamus (Johansson & Silfvenius, 1977).…”

SUMMARY1. Records were made from axons in the dorsal columns and cells in the cuneate nucleus which responded to stimulation of the wrist joint nerve.2. A sample of twenty-five axons activated by the wrist joint nerve was recorded in the dorsal columns at the level of the third cervical segment. All twenty-five were post-synaptic fibres as judged by response latency, burst length, and maximum frequency of following. Nineteen of the twenty-five had convergent inputs from the wrist joint nerve and the cutaneous superficial radial nerve.3. While no primary wrist joint afferent fibres were recorded in the dorsal columns, their presence was demonstrated by recording single units in the wrist joint nerve which were antidromically activated by microstimulation in the cuneate fasciculus.4. The majority of cells recorded in the cuneate nucleus were activated not only by stimulation of joint afferents, but also by skin and muscle afferent fibres.5. About half of the cells in the cuneate nucleus responded to wrist movement in animals with partially denervated forelimbs, where the intact wrist joint nerve was the only afferent channel providing information about natural, imposed wrist movements. The majority of the cells had phasic responses, which were weak and irregular in comparison with the responses of primary wrist joint afferents to the same movements.6. Only two of thirty-four cells tested could be shown to project directly to the ventrobasal thalamus, using collision of antidromic and peripherally activated impulses as the criterion.

“…However, none of DSCT neurones of the muscle group was found to receive excitatory inputs from more than one muscle nerve (but, cf. Mann, 1971 (Brown, 1968;Burgess & Clark, 1969a;Whitehorn Cornwall & Burgess, 1971). The presence or absence of activation of a DSCT neurone by antidromic stimulation of the dorsal column apparently depended on the source of the peripheral sensory input to the neurone (Table 1).…”

“…This behaviour was consistent with a lack of activation of these DSCT neurones by antidromic stimulation of the dorsal column (Table 2). It has been shown that rapidly adapting joint receptors are characterized by the fibre projection to the cervical cord through the dorsal column, whereas slowly adapting joint receptor fibres have no direct projection to the high level of the spinal cord (Burgess & Clark, 1969a Methods). The site of recording was marked only when the extracellular response showed a biphasic configuration (soma response, see above) with peak-to-peak amplitude in excess of 2 mV.…”

SUMMARY1. Discharge of neurones at the region of Clarke's column of the cat was recorded intracellularly or extracellularly in response to electrical stimulation of various hind limb nerves or to adequate stimuli applied to a variety of sensory receptors.2. According to the type of excitatory sensory input, the neurones were classified into four groups. Their relative proportions were: muscle group, 55-65 %; cutaneous group, 15-25 %; joint group, 5-15 %; convergent group, 10-20%.3. The location of the neurone cell bodies was examined by marking the site of extracellular recording with fast green. The neurones of the muscle or cutaneous group were found to be within Clarke's column. One out of four neurones tested for the joint group and two out of six cells examined for the convergent group were found to be located outside the column.4. There was no difference in axonal conduction velocity among the neurones of different groups.5. The neurones of different groups could be distinguished in terms of the pattern of discharges recorded under 'resting' conditions and during activation of sensory receptors. It is suggested that information carried by dorsal spinocerebellar tract neurones to the cerebellum has a lower signal-to-noise ratio for cutaneous inputs than for muscle or joint inputs.

Recently, rising curiosity on remnant preservation technique of anterior cruciate ligament (ACL) reconstruction, there is much interested in being and distribution of the mechanoreceptor of ACL. So, we performed histologic analyzing and mapping of sensory nerve fiber of the human ACL in this study. Total of 20 anterior cruciate ligaments were obtained from total knee replacement. Each ACL samples was divided into seven specimens; tibial insertion site, mid transitional site, femoral insertion site, and in between the sites, and total of 140 tissue samples were stained with hematoxylin-eosin and immunohistochemical, and observed with light microscope. Five hundred thirty-four fine neuroparticle structures, Ruffini corpuscles, and free nerve endings were observed in 20 ACL samples. The mean of fibers observed were 1.88, 1.71, 1.15, 1.08, 1.15, 1.55, and 1.82, respectively from tibial insertional site to femoral insertional site. With immunohistochemical stain, S-100 protein was strong positive at nerve cells, but was weak positive or negative at neurofilament. Mapping of sensory nerve distribution were done based on the results. We identified the mechanoreceptor of the human ACL using optical and immunohistochemical methods and mapped the histologic distribution of that. 는 전방십자인대의 기
