Studies on preconditioning with adenosine, glutamate and ouabain in rat hippocampal slices
… evoked field epsps, orthodromic and antidromic population spikes. Western blotting was used to detect any changes in the levels of HSP72 in the slices that may have occurred as a result of the depolarizing agents or the preconditioning treatments. It was first established that 5mM and …

Functional Consequences and Mechanism of Lsd Action in the Lateral Eye of Limulus
… cells while producing inhibition via light and antidromic stimulation in the presence of 5-HT, LSD, chlorimipramine, and a bathing medium high in Mg('++) and low in Ca('++) which partially or completely blocks synaptic transmission.

An Electrophysiological Analysis of the Primary Input to the Cat Prepyriform Cortex
… indicative of convergence from several axons. Antidromic axons had punctate threshold points.</p> <p>Centrifugal axons originating from cortical neurons were found in the olfactory tract. To show this, middle prepyriform cortical neurons were antidromically driven by peduncular volleys. …

Pontomedullary reticular formation neurones : a study of microanatomy, transmitter sensitivity and connections from the substantia nigra pars reticulata
… electrode was used to combine antidromic stimulation of PMRF cells with optimal retrograde labelling. 139 PMRF neurones were identified by means of their stereotaxic location and physiological criteria, namely; spontaneous discharge, polymodal sensory responses and large …

ELECTROPHYSIOLOGICAL ANALYSIS OF THE RECURRENT RENSHAW CIRCUIT
… brief electrical shocks used to activate single antidromic impulses in single motor axons, either by way of an intra-axonally positioned microelectrode in the muscle nerve or by microstimulation of the muscle supplied by the axon. The resultant average revealed the motoneuron's response to each …

Stabilization of the Cardiac Nervous System During Cardiac Stress Induces Cardioprotection
… cardiac-related afferents, doing so without antidromic activation of the primary cardiac afferents. Instead, thoracic SCS acts through altering the cardiac milieu thereby secondarily affecting the primary afferent sensory transduction. In response to cardiac stressors, reflex activation of …

The neurotoxicity of acrylamide
… acrylamide although a possible compromise of antidromic action potential conduction could not be confirmed. There was no histopathological evidence of neuropathy at this dose level. Further exploration of this phenomenon is desirable in order to ascertain whether the effect is specific to …

Supraspinal actions of pentobarbital on transmission through the spinothalamic tract
… PB into the MPTA. Spontaneous firing rate (SFR), antidromic firing index (FI) and sciatic as well as sural nerve-evoked responses (Sc-, Su-ER) of STT neurons in isoflurane-anesthetized rats were quantified before as well as 2, 15, 30 and 60 min following bilateral microinjections of either PB (200 …

Pitx3Null Mutant (Striatal Dopamine-Deficient) Mice Have Exaggerated Spiny Projection Neuron Responses to l-DOPA and D1 Agonism and Lack Baseline Striatonigral Spiking
… striatal regions. Furthermore, antidromically identifying dorsal SPNs allowed us to putatively distinguish a particularly relevant subset (striatonigral, D1-SPNs or d[irect]SPNs) known to elicit movement; serendipitously we also identified putative fibers of passage that strongly …
