Calcium currents of differentiated mouse neuroblastoma cells
Neurophysiology - 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
Effects of Neural Crest-Derived Multipotent Stem Cells on Regeneration of an Injured Peripheral Nerve in Mice
Neurophysiology - Tập 47 - Trang 80-83 - 2015
R. G. Vasyliev, A. E. Rodnichenko, S. N. Shamalo, A. S. Demidchouk, I. F. Labunets, Yu. B. Chaikovskii, G. M. Butenko
We studied the effect of transplantation of neural crest-derived multipotent stem cells (NC-MSCs) obtained from vibrissa germs on regeneration of the injured (transected) sciatic nerve in adult mice (strain FVB). After transplantation of the cells into the injured region, regeneration of the severed nerve was intensified, as compared with that in mice with no implantation. The intensity of vascula...... hiện toàn bộ
Spinal Cord Circuits: Models and Reality

Spike generation by spinal neurons evoked by sinusoidal depolarization in cats
Neurophysiology - Tập 14 Số 1 - Trang 27-33 - 1982
A. I. Kostyukov, M. V. Kryzhanovskii
On mechanisms of depression in pathways of presynaptic inhibition
Neurophysiology - 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 Control
Neurophysiology - 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
Effects of the γ-aminobutyric acid antagonist disulfotetraazaadamantane on evoked neuronal response in hippocampal slices
Neurophysiology - Tập 21 - Trang 57-60 - 1989
G. Ya. Pervukhin, I. N. Sharonova, S. E. Prokof'ev, N. B. Fedorov, S. A. Kotel'nikov, V. I. Fetisov, I. V. Martynov
The effects were investigated of disulfotetraazaadamantane (DSTA), a blocker of γ-aminobutyric acid, on summated potentials in field CA 1 of the mouse hippocampus arising in response to electrical stimulation of Shaffer's collateral. At a concentration of 5·10−6–10−5 M, DSTA led to a considerable increase in the amplitude of the main population spike (PS) and the onset of additional PS. The effect...... hiện toàn bộ
Recombinant extracellular domains of human neuronal nicotinic receptors: Preliminary studies on mutant forms for the improvement of solubility
Neurophysiology - Tập 39 - Trang 259-263 - 2007
M. Zouridakis, P. Zisimopoulou, E. Eliopoulos, L. Jacobson, K. Poulas, S. J. Tzartos
An extracellular domain (ECD) of the human α7 neuronal nicotinic acetylcholine receptor (nAChR) is implicated in a series of neurological disorders. To facilitate structural studies of this domain essential for rational drug design, we designed and expressed mutated forms of human α7 ECD in yeast Pichia pastoris. The novel mutations were based on a model we constructed for α7 ECD using crystal and...... hiện toàn bộ
Effects of Chronic Neurogenic Stress on Behavior of Rats and Contents of Sphingolipids in Their Brain and Peripheral Tissues
Neurophysiology - Tập 48 - Trang 346-353 - 2017
N. A. Babenko, V. M. Shevereva, V. V. Gar’kavenko
We studied the contents of ceramide and sphingomyelin (SM) in the hippocampus, neocortex, and peripheral tissues of rats and the behavior characteristics of these animals in the open field at different times after the induction of chronic neurogenic stress. The experiments were carried out on young Wistar rats weighing 180–220 g, with a mean level of behavioral mobility. Within the poststress peri...... hiện toàn bộ
