Title: [Evoked potentials of the dog sensomotor cortex following systematic application of series of electrocutaneous stimuli]. Author: Pressman IaM. Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1978; 28(6):1184-9. PubMed ID: 735381. Abstract: Standard 5-member series of weak electro-cutaneous stimulations of the fore-paw were applied in chronic experiments to two dogs with implanted cortical electrodes. The stimuli caused no apparent motor reactions and were not reinforced by any other type of stimulation. Evoked potentials (EP) in the sensorimotor cortex were gradually forming in the course of experiments in such a way that the amplitude of averaged EPs to the extreme stimuli of the series became larger than those to the middle ones. The elaborated U-shaped dependence of the averaged EP amplitudes in the sensorimotor cortex on the ordinal number of the electrical stimuli correlates with the same EP dependence observed in the auditory cortex of dogs in response to series of clicks. The described form of EP organization in response to the stimuli of one modality facilitates the elaboration of the same type of organization in response to the stimuli of an other modality.[Abstract] [Full Text] [Related] [New Search]
