[Changes in spino-bulbo-spinal reflexes during activation and inactivation of the locus coeruleus in the cat].
In cats anesthetized with chloralose the long lasting depression of spino-bulbo-spinal (SBS) discharges following short repetitive stimulation of the locus coeruleus (LC) was revealed. Inactivation of LC by procaine microinjections resulted in remarkable enhancement of SBS discharges. These data evidence for prominent inhibitory modulatory influences from locus coeruleus on SBS reflexes which are presumably performed mainly on supraspinal level.
