[Recording of electromyogram in chronic experiments in dogs]

A connector for chronic recording of EMG activity located on the dog's neck was developed as a row of male pins fixed on a dense band with attached wires of intramuscular electrodes. The wires were subcutaneously led to the connector. The band of the connector was sutured at the corners to the skin of the dorsal surface of the neck. Then the connector was anchored to the neck by a double adhesive tape wrapping like a collar. Compared to scull connectors, our model provided minimum surgical trauma to the animal, the connector or wires of intramuscular electrodes can be replaced if necessary. Localization of the connector did not impede scull and brain surgical operations. The model has been described and tested in the experiments in seven dogs with 8-20 pairs of implanted EMG-recording electrodes within 2-10 weeks.
