[Role of cholinergic mechanisms in central regulation of respiratory activity in Periplaneta americana cockroaches].
Studies have been made on cholinergic mechanisms in the thoracic ganglion of the cockroach P. americana. It was shown that cholinergic systems are involved not only in the transmission of excitation, but in realization of the inhibitory effects as well. Both types of cholinereceptors were found on motoneurones. Nicotinic, muscarinic or both of the cholinoreceptors may be present on a single interneurone. Nicotinic cholinoreceptors play key role in transmission of excitation. Both types of the cholinoreceptors are involved in realization of the inhibitory influences.
