Pagination or Media Count:
Properties of the atropine-sensitive slow synaptic responses in mammalian sympathetic ganglia were further analyzed as to their 1 postsynaptic origin, 2 transmitter substances, and 3 durations of synaptic delays for each. Intracellular studies on single ganglion cells of frogs sympathetic ganglia are also reported in relation to 1 atropine-sensitivity of true after-potentials and 2 pre- and postsynaptic blocking action of curariform substances. The actions of other nicotinic blocking agents hexamethonium, mecamylamine on frog ganglionic synaptic responses are also reported. Developments in the technique for intracellular recording in mammalian ganglia are described.
