  • Title: [Effect of cholinolytics on the functional lability of the visual analyzer in cats].
    Author: Kal'ning SA.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1980; 30(3):562-6. PubMed ID: 6108025.
    Abstract:
    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. It was noted that the frequency of white, yellow, green and blue photic stimuli is reproduced on ERG within the range from 1 to 23 c/s both before the administration of cholinolytics and during their action in all of the used doses. Flash rhythm reproduction was not disturbed (in spite of an increase in the waves' amplitudes in the retinal background bioelectrical activity) following administration of cholinolytic substances. All cholinolytics in all of the studied doses caused in the EEG of the visual cortex an increase in waves' amplitude, i. e. a synchronization.
