“…Every identified Pacinian corpuscle-like receptor projected, but more than 50 % of the phasic joint receptors could not be activated from the cervical dorsal columns. Gardner, Latimer & Stillwell (1949) also show relatively few projecting fibres with gross recording from the posterior articular nerve during dorsal column stimulation. Recent studies ; see also Brown, 1968) have indicated that more than 80 % of the fibres projecting to cervical dorsal column levels from the cat sural nerve supply rapidly adapting receptors.…”

1. Stimulation of the cervical dorsal columns excited an average of nine knee joint fibres in the cat posterior articular nerve, eleven fibres in the cat medial articular nerve and thirteen fibres in the monkey posterior articular nerve. 2. Joint fibres projecting to cervical levels were shown to be rapidly adapting by recording with micro‐electrodes from single fibres in intact cat posterior articular nerves. The numerous slowly adapting fibres could not be antidromically excited from the cervical dorsal columns. 3. Several control experiments suggested that the antidromic stimulation method accurately defined the dorsal column projection of joint fibres.

“…Sensory fibers from joints are thought to carry information about limb position and to enter the dorsal columns proceeding without interruption to the dorsal column nuclei (Brodal, 1948;Gardner, Latimer, and Stilwell, 1949;Skoglund, 1956;Mountcastle and Powell, 1959;Rose and Mountcastle, 1959). However, in a recent study Burgess and Clark (1969a) found relatively few fibers from the cat knee projecting to cervical levels in the dorsal columns with an average 5% or 9 fibers from the posterior, and 7% or 11 fibers from the medial articular nerves.…”

SUMMARYThe dorsal column projections of individual primary afferent fibers from the posterior articular nerve innervating the cat knee have been studied. The majority of fibers not projecting to cervical levels in the dorsal columns supply slowly adapting receptors. These fibers undergo a reduction in conduction velocity shortly after entering the dorsal columns and terminate in the upper lumbar to lower thoracic region of the spinal cord.

“…First, however, they give collaterals which, together w ith term inal prim ary aflerents, establish widespread synaptic connections (Gardfor nerve impulses from joints 205 neii [1948a], Gardner, Latimer and Stilwell [1949]). Impulses destined for the brain stem and cerebral and cerebellar cortex by other than the dorsal funiculus-m edial lemniscus system arise front these spinal connections and ascend by way of several pathw ays.…”
