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
Positioning of the Human Forearm in Tracking Movements and Their Reproduction under Conditions of Limited Visual ControlNeurophysiology - Tập 35 - Trang 122-132 - 2003
A. P. Mel'nichouk, N. V. Bulgakova, D. A. Vasilenko
In 14 healthy persons, we studied movements of the forearm with its positioning on a target level. A double trapezium was used as the command trajectory (flexion in the elbow joint from the state of full extension, 0°, with positioning on the level of 50 or 60° and further flexion to the 100° angle, and a similar reverse movement). We compared (i) tracking movements, when the subject tried to adeq...... hiện toàn bộ
Localization of biogenic amines and monoamine oxidase in the rabbit hippocampusNeurophysiology - Tập 5 - Trang 30-36 - 1973
I. V. Torskaya, L. F. Burchinskaya, V. V. Korotchenko
Comparison of the localization of monoamines and monoamine oxidase in the rabbit hippocampus shows that most pyramidal and all granular neurons contain no monoamines. Up to 1% of pyramidal and about 3% of polymorphic neurons are noradrenergic, and some of the latter are basket cells. Their terminals, containing both noradrenalin and monoamine oxidase, are in contact with the bodies and processes o...... hiện toàn bộ
Parameters of Components N2 and P3 of the Auditory Cognitive Evoked Potentials in Musicians and Non-musiciansNeurophysiology - Tập 50 - Trang 203-208 - 2018
A. G. Okhrei, N. V. Kutsenko, N. Yu. Makarchuk
We measured time parameters of the cognitive components in the auditory evoked potentials in professional musicians and non-musicians in order to determine electrophysiological correlates of the information processing rate and differentiation of the stimuli in such examined groups. It was found that the latencies of components N2 and Р3 were, on average, shorter in subjects that professionally pra...... 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
