Selective depressant action of antidromic impulses on gustatory nerve signals
The depressant action of antidromic volleys of impulses on gustatory nerve signals from the tongues of bullfrogs was studied. Electrical stimulation of the glossopharyngeal nerve at a rate of 100 Hz for 10 s and at supramaximal intensity slightly depressed the integrated glossopharyngeal nerve responses to quinine and to mechanical taps to the tongue. The same antidromic stimuli resulted in a 3...
متن کاملSome Problems Relating to the Dorsal Spinal Nerve Roots *
Discussion in the past has centered around three particular aspects of the dorsal spinal roots. I refer specifically to the possible "pain pathway" along unmyelinated nerve fibres, the location of the cell station of the visceral afferent fibres, and the explanations offered for the vasodilator response obtained by stimulation of the distal ends of the dorsal spinal roots. Opinion is now settli...
متن کاملCentral effects of centripetal impulses in axons of spinal ventral roots.
THE EXPERIMENTS of Muller (18) and others demonstrated that stimulation of the central end of a severed ventral spinal root does not result in the production of muscular movements; that is to say, an antidromic volley of impulses in a group of motor axons does not result in the discharge of other motoneurons. However, such antidromic volleys are not without effect on the spinal cord. It is well...
متن کاملAntidromic Sensory Conduction
Sears (1959) stimulated the median nerve at the wrist and recorded the antidromically evoked sensory potential from the fingers. Since a larger response is usually obtained with antidromic conduction (Buchthal and Rosenfalck, 1966), and as its latency has been believed to be identical with that of orthodromic conduction (Campbell, 1962; Ruskin and Rogoff, 1964; Goodgold and Eberstein, 1972), th...
متن کاملElectrophysiology of the Insect Dorsal Ocellus II. Mechanisms of generation and inhibition of impulses in the ocellar nerve of dragonflies
I N T R O D U C T I O N T h e insect dorsal ocellus contains a layer of pho to recep to r cells, a synapt ic region in which axons of the pho to recep to r cells come into contac t with dendri tes of ocel lar nerve fibers (the cell bodies of which lie in the brain) , and an ocellar nerve along which the ocellar nerve fibers pass into the brain. T h e ocellar E R G can be ana lyzed into four com...
