[Effect of catecholamines and their antagonists on the responses of the dental areas of the cerebral cortex evoked by dental pulp stimulation in the rabbit].
The primary responses of the dental areas of the brain cortex in anesthetized rabbits were recorded to demonstrate that application of the alpha-adrenomimetic noradrenaline and beta-adrenolytic propranolol to the cortex suppressed, while application of the beta-adrenomimetic isadrin and alpha-adrenolytic phentolamine potentiated the electrical responses to nociceptive stimulation of the dental pulp. It was found that phentolamine exerted dissimilar effects.
