Calcium currents of differentiated mouse neuroblastoma cellsNeurophysiology - Tập 16 - Trang 419-422 - 1984
N. S. Veselovskii, N. Kh. Pogorelaya, A. F. Fomina
Differentiated mouse neuroblastoma cells (line C 1300, clone N-18-TG2A1) were investigated by intracellular dialysis. A slow component was found in the potential-dependent inward current of these cells. The results of investigation of changes in amplitude of this component during variation of the ionic composition of the external and internal solutions showed that this component is due to transpor...... hiện toàn bộ
On mechanisms of depression in pathways of presynaptic inhibitionNeurophysiology - Tập 1 - Trang 192-198 - 1969
P. E. Motsnyi, T. F. Dneprovaya
We investigated inhibition of the N1-component of the spinal cord dorsal potential (CDP) evoked by experimental stimulation of the n. peroneus in spinal cats. Stimulation was carried out following two conditioning stimuli administered at different time intervals to the same or different cutaneous nerves. The interval between the last conditioning stimulus and the experimental one remained constant...... hiện toàn bộ
Model investigation of firing mechanisms of mammalian neuronsNeurophysiology - Tập 16 - Trang 347-352 - 1984
S. L. Mironov
A model of electrical activity of mammalian neurons, based on properties of the corresponding ionic components of the transmembrane current, is suggested. Its analysis showed that two types of firing are possible for these neurons. First, the firing pattern is determined by fast sodium and delayed potassium currents, and the period of oscillations is 74±27 msec. Second, the firing pattern is deter...... hiện toàn bộ
Inhibitory Postsynaptic Currents Induced by Activation of Interneurons in Cultured Rat Hippocampal NeuronsNeurophysiology - Tập 37 - Trang 104-110 - 2005
A. A. Moskalyuk, O. M. Koval', S. A. Fedulova, N. S. Veselovskii
Using the patch-clamp technique in the whole-cell configuration, we studied the characteristics of a series of action potentials (APs) induced by a 500-msec-long current pulse applied to a pre-synaptic unit, as well as the kinetic characteristics of post-synaptic currents (PSCs) evoked by the APs in a post-synaptic unit, in synaptically connected pairs of cultured hippocampal neurons. Presynaptic ...... hiện toàn bộ
Common features of antigenic determinants present on mammalian nerve cell membrane structures and in cytoplasmic tetrodotoxin-sensitive proteinsNeurophysiology - Tập 19 - Trang 276-278 - 1987
M. K. Malysheva, G. V. Pinchuk, L. I. Kolchinskaya, V. A. Zhukareva, A. N. Nikolaenko, S. A. Klincheva, P. G. Klering
Possible antigenic features common to nerve cell membrane structures and cytoplasmic tetrodotoxin-sensitive proteins were investigated by means of an immobilized immunoenzyme test. It was found that antiserum obtained by immunizing rabbits with a purified preparation of cytoplasmic tetrodotoxin-sensitive proteins can react with antigenic determinants present on the membrane fraction of bovine brai...... hiện toàn bộ
Inhibitory effects of reticulospinal fibers of the lateral funiculus on neurons of thoracic spinal reflex pathwaysNeurophysiology - Tập 10 - Trang 110-119 - 1978
A. P. Gokin
Experiments on anesthetized cats with partial transection of the spinal cord showed that reticulo-spinal fibers in the ventral part of the lateral funiculus participate in the inhibition of polysynaptic reflexes evoked by stimulation of the ipsi- and contralateral reticular formation. The reticulo-fugal wave in the ventrolateral funiculus evoked comparatively short (up to 70 msec) IPSPs in some mo...... hiện toàn bộ
