[Effect of noradrenaline on spatial synchronization and evoked potentials in the cerebral cortex of the rabbit].
Noradrenaline application on the cerebral cortex of rabbits leads to an increase of the level of spatial correlation of neocortical potentials. At low doses of noradrenaline, the amplitude of EPs in the visual cortex initially decreases and then increases. With increases of the noradrenaline dose, the amplitude of EPs continues to increase. Amplitude of the EPs is enhanced also in the sensorimotor cortex for which the light stimuli are not specific. Analysis of data obtained and those published by other authors, allows to suppose that in the process of conditioning, noradrenaline may act as a positive as well as a negative reinforcing factor depending on the type and the stage of conditioning.
