  • Title: [Effect of beta-phenylethylamine on evoked potentials of the neostriatum of rats].
    Author: Zharikova AD, Godukhin OV.
    Journal: Biull Eksp Biol Med; 1979 Oct; 88(10):395-8. PubMed ID: 497377.
    Abstract:
    The effect of intraperitoneal (70 mg/kg) and local (39 ug) administration of beta-phenylethylamine (beta-PEA) on evoked potentials (EP) in the caudate nucleus upon stimulation of substantia nigra zona compacta (SNC) and frontal cortex in rats has been studied. beta-PEA, glutamate and haloperidol were injected into the caudate nucleus by means of a system consisting of a pushpull cannule and an electrode for simultaneous registration of EP. Specificity in the effect of the drugs on EP in response to stimulation of the cortex and substantia nigra was revealed. The intraperitoneal injection of beta-PEA induced, comparatively to the application, more rapid and potent decrease in the amplitude of the component (N2-P2) as a result of the substantia nigra stimulation and slightly influenced the EP amplitude in stimulation of the frontal cortex. It was established using haloperidol that the component (N2-P2) of EP in response to the substantia nigra stimulation is of dopaminergic neuron function in the nigro-neostrital system of the rat brain.
