  • Title: [Reflection of the intensity of peripheral stimulation in the amplitude-time parameters of somatosensory and kinesthetic evoked potentials of the projection cortex in rhesus macaques].
    Author: Fedan VA.
    Journal: Zh Evol Biokhim Fiziol; 1988; 24(1):53-60. PubMed ID: 3376635.
    Abstract:
    Experiments were made on 7 adult male monkeys under nembutal anaesthesia (20-25 mg/kg, intravenously). The evoked potentials to electrical stimulation (0.5-50 mA) of the skin and kinestetic (5.10(3)-6.10(5)degrees/s2) stimulation of the proximal part of the forearm were recorded in the contralateral primary somatosensory cortex. The data obtained indicated direct relationship between the magnitude of angular acceleration and amplitude-temporary parameters of the kinestetic potentials. The threshold for their detections was equal approximately to 5.10(3) degrees/s. Maximum amplitude and the shortest latency were observed at accelerations 100 times higher than threshold ones. These data are compared with parameters of the evoked potentials to the electrical stimulation of the skin.
