Intracochlear and extracochlear ECAPs suggest antidromic action potentials.
With experimental animals, the electrically evoked compound action potential (ECAP) can be recorded from multiple sites (e.g., round window, intracranial and intracochlear sites). However, human ECAPs are typically recorded from intracochlear electrodes of the implanted array. To bridge this difference, we obtained ECAPs from cats using both intracochlear and nerve-trunk recording sites. We als...
متن کاملSelective 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 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 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...
متن کاملBDNF mRNA abundance regulated by antidromic action potentials and AP-LTD in hippocampus
Action-potential-induced LTD (AP-LTD) is a form of synaptic plasticity that reduces synaptic strength in CA1 hippocampal neurons firing antidromically during sharp-wave ripples. This firing occurs during slow-wave sleep and quiet moments of wakefulness, which are periods of offline replay of neural sequences learned during encoding sensory information. Here we report that rapid and persistent d...
