[Effect of adrenergic compounds on the brain potentials evoked by stimulation of the dental pulp].
Intraventriculare injections have brough evidence that alpha-adrenomimetic norepinephrine and beta-adrenomimetic isopropylnorepinephrine augment in the senso-motor region of the cortex the amplitude of primary responses evoked through a dental pulp stimulation. The alpha-adrenoblocking agents--dihydroergotoxin and phentolamine and the beta-edrenoblocking agent propranolol force down the amplitude of primary responses. The sphere of the drugs action is presumed to be the thalamic nuclei.
