[Effect of cholinolytics on the functional lability of the visual analyzer in cats].

The effect of aminoethers of derivates of glycolic acid (glipine and amizil) in doses of 0.1--5 mg/kg and of derivates of acetic acid (diphacyl and thropacin) in doses of 10--40 mg/kg on bioelectrical activity of the retina was studied in experiments on 10 intact cats. To control the effect of cholinolytics, electrodes were chronically implanted in the visual cortex and EEG ws recorded.

[The effect of M-cholinolytics on the lability of rabbit visual analyzer structures].

The influence of M-cholinolytics (amizyl, glipine, cyclozyl and 4-oxypiperidylbenzylate) in 0.01--10 mg/kg doses on EEG and photic driving in structures of the visual analyser was studied in experiments on twenty intact rabbits with chronically implanted electrodes in the optic chiasm, the optic tract, the lateral geniculate body and the visual cortex. All M-cholinolitics in the doses studied produced synchronization of the EEG.
