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.
