Two types of changes in skin conductance activity after intraventricular administration of 6-hydroxydopamine in rats. 1985

K Yamamoto, and H Kiyosumi, and K Yamaguchi, and T Moroji

Sixteen male Wistar strain rats were trained to have their skin conductance activity recorded through the soles of their hind limbs, and the effects of the intraventricular administration of 6-OHDA (200 micrograms) on this activity were studied. The intact rats showed skin conductance response and its habituation to repeated auditory stimuli (500 Hz, 90 dB, 1 sec). The 6-OHDA-treated rats exhibited either obliteration of the response or impairment of the habituation. The nonresponding state tended to be accompanied by a low rate of spontaneous skin conductance fluctuation, but the nonhabituating state was not accompanied by changes of the rate. The vehicle-treated rats showed no change in these activities. These electrodermal characteristics were discussed along with the CA hypothesis of schizophrenia.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001679 Biogenic Amines A group of naturally occurring amines derived by enzymatic decarboxylation of the natural amino acids. Many have powerful physiological effects (e.g., histamine, serotonin, epinephrine, tyramine). Those derived from aromatic amino acids, and also their synthetic analogs (e.g., amphetamine), are of use in pharmacology. Amines, Biogenic,Biogenic Amine,Amine, Biogenic
D016627 Oxidopamine A neurotransmitter analogue that depletes noradrenergic stores in nerve endings and induces a reduction of dopamine levels in the brain. Its mechanism of action is related to the production of cytolytic free-radicals. 6-Hydroxydopamine,6-OHDA,Oxidopamine Hydrobromide,Oxidopamine Hydrochloride,6 Hydroxydopamine,Hydrobromide, Oxidopamine,Hydrochloride, Oxidopamine
