Synaptic inhibitory effects of edrophonium on sympathetic ganglionic transmission

Vascular effects of procaine amide in the dog. Predominance of the inhibitory effect on ganglionic transmission.

Slow synaptic transmission in frog sympathetic ganglia.

Bullfrog ganglia contain two classes of neurone, B and C cells, which receive different inputs and exhibit different slow synaptic potentials. B cells, to which most effort has been directed, possess slow and late slow EPSPs. The sEPSP reflects a muscarinic action of acetylcholine released from boutons on B cells, whereas the late sEPSP is caused by a peptide (similar to teleost LHRH) released ...

Inhibitory effects of arachidonic acid on nicotinic transmission in bullfrog sympathetic neurons.

Inhibitory effects of arachidonic acid on nicotinic transmission in bullfrog sympathetic neurons. J. Neurophysiol. 78: 2396-2401, 1997. Arachidonic acid (AA, 0.2-40 mu M) reversibly reduced the amplitude of the fast excitatory postsynaptic potentials and the underlying currents (fast EPSCs) of bullfrog sympathetic neurons evoked by preganglionic nerve stimulation in a Ca2+-deficient solution. A...

Inhibitory synaptic transmission governs inspiratory motoneuron synchronization.

Neurons within the intact respiratory network produce bursts of action potentials that cause inspiration or expiration. Within inspiratory bursts, activity is synchronized on a shorter timescale to generate clusters of action potentials that occur in a set frequency range and are called synchronous oscillations. We investigated how GABA and glycine modulate synchronous oscillations and respirat...

Effects of clozapine and N-desmethylclozapine on synaptic transmission at hippocampal inhibitory and excitatory synapses.

Clozapine is the first atypical antipsychotic, and improves positive and negative symptoms of many patients with schizophrenia resistant to treatment with other antipsychotic agents. Clozapine induces minimal extrapyramidal side effects, but is more often associated with seizures. A large number of studies have been conducted to elucidate pharmacological profiles of clozapine and its major acti...
