[Experimental studies of the role of the adrenergic system in the development of bioelectric response of the retina and visual cortex. IV. Visual evoked potentials in rabbits after administration of alpha and beta receptor agonists and blockaders].
The influence of noradrenaline, dihydroergotamine, isoprenaline and propranolol on the VEP in rabbit was examined. The records of VEP showed a lowering of the amplitude of the A and B waves after compounds stimulating and restraining the adrenergic alpha and beta receptors. The C wave increased after dihydroergotoxine, isoprenaline and propranolol; it was lowered after noradrenaline. On the basis of the obtained results the author discusses the role of the adrenergic system in formation of the bioelectric response of the visual cortex.
