Sensory nerve action potentials in patients with peripheral nerve lesions.
In 1949 Dawson and Scott described a method of examining sensory impulses in human peripheral nerves. By their technique, the median or ulnar nerve at the level of the wrist was stimulated electrically using single shocks, and the action potential of the afferent volley recorded through surface electrodes placed over the nerve trunk at a higher level in the arm. The afferent volley contained bo...
متن کاملSensory transduction in peripheral nerve axons elicits ectopic action potentials.
Sensory properties of unmyelinated axons in the isolated rat sciatic nerve have been revealed previously by measuring stimulated neuropeptide release in response to noxious stimuli. In addition, axonal sensitization by inflammatory mediators has been demonstrated and shown to depend on the heat- and proton-activated ion channel transient receptor potential vanilloid receptor-1. It was unclear w...
متن کاملProperties of action potentials from insect motor nerve fibres.
Extracellular recording from small nerve branches provides a method for recording from several nerve fibres simultaneously. This is extremely desirable in studying the organization of a neuronal system. Furthermore, extracellular records are insensitive to small movements, are stable over long periods, and can easily be repeated with subsequent experimental animals. They also involve relatively...
متن کامل"amplitudes of sural and radial sensory nerve action potentials in orthodromic and antridromic studeis in children"
several previous studies of adults have reported that the amplitudes of the sural and superficial radial nerve (sn and srn) action potentials are larger with antidromic than with orthodromic recordings. however, this difference has not been documented in children. this study evaluated the amplitudes of sn and srn sensory nerve action potentials (snaps), obtained with antidromic and orthodromic ...
متن کاملAmplitudes of sural and radial sensory nerve action potentials in orthodromic and antidromic studies in children.
Several previous studies of adults have reported that the amplitudes of the sural and superficial radial nerve action potentials (SN and SRN SNAP respectively) are larger with antidromic than with orthodromic recordings. However, this difference has not been documented in children. This study evaluated the amplitudes of SN and SRN SNAPs obtained with antidromic and orthodromic recordings in chi...
