Description
Summary:	The mechanisms of inhibitory effect of transcranial electrostimulation in analgesic regime on blood pressor nociceptive reflexes were studied in experiments in rabbits and cats. Considerable inhibition of the late (bulbar) somato-sympathetic reflexes and spino-bulbo-spinal somato-somatic reflexes as well was demonstrated. The probable basis of sympatho-inhibition during transcranial electrical stimulation is a reduction of excitatory input to bulbar sympathoexcitatory neurons. It was revealed in experiments with inhibition of sympatho-excitation elicited by temporal brain ischaemia and local electrical stimulation of different bulbar ventrolateral vasomotor zones. The role of periaqueductal gray activated by transcranial electrical stimulation as a source of inhibition and its opioid mechanisms are discussed.
