Gamma->alpha linkage and persistent firing of Ia fibers by pudendal nerve stimulation in the decerebrate cat.
The sensory pudendal nerve (SPN) was stimulated in decerebrate female cats. Spikes of single Ia muscle spindle afferents from the medial gastrocnemius (MG) muscle were recorded in dorsal root filaments. Electroneurography (ENG) was recorded in a cut nerve filament to the MG muscle; MG electromyography (EMG) was also recorded. Single shock to SPN induced discharges of small ENG spikes (SS) with ...
متن کاملCentral command, but not muscle reflex, stimulates cutaneous sympathetic efferents of cats.
We determined the effects of stimulation of the mesencephalic locomotor region (MLR) and the muscle reflex, each evoked separately, on the discharge of cutaneous sympathetic fibers innervating the hairy skin of decerebrate cats. Electrical stimulation of the MLR was performed while the cats were paralyzed with vecuronium bromide. The muscle reflex was evoked while the cats were not paralyzed by...
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...

متن کاملMuscle afferent contribution to control of paw shakes in normal cats.
1. The discharge of various hindlimb muscle afferents was recorded during paw shakes in normal cats with the use of floating dorsal root electrodes. 2. Muscle spindle group Ia-afferents and tendon organ group Ib-afferents fired during muscle lengthening, reaching very high peak discharge rates and then silencing at or shortly after the onset of shortening. The timing of Ia firing was consistent...
