Đặc điểm của độ tương thích của hoạt động EEG trong trạng thái nghỉ của các đối tượng với các mức độ hung hăng khác nhau Dịch bởi AI
Neurophysiology - Tập 44 - Trang 144-152 - 2012
Bằng cách phân tích độ tương thích của hoạt động EEG, chúng tôi đã xem xét sự tổ chức không gian của hoạt động này ở 60 người trưởng thành thuộc cả hai giới tính có mức độ khác nhau của các khía cạnh hung hăng và thù địch (được chẩn đoán thông qua các bảng hỏi Buss–Durkee và Il’yin). Việc ghi nhận EEG (21 đầu điện được đặt theo hệ thống 10-20) được thực hiện trong trạng thái nghỉ. Số lượng lớn nhấ...... hiện toàn bộ

Cholinergic excitation of smooth muscles: Multiple signaling pathways linking M2 and M3 muscarinic receptors to cationic channels
Neurophysiology - Tập 36 - Trang 398-406 - 2004
Acetylcholine, the main neurotransmitter of the parasympathetic nervous system, depolarizes various smooth muscles and initiates their contraction via activating muscarinic cholinergic receptors. In most visceral smooth muscle tissues, such as the gastrointestinal tract, airways, and the urinary system, muscarinic receptors are comprised of predominant M2 (about 80%)and minor M3 (about 20%) subtyp...... hiện toàn bộ
Sodium and calcium channels in the somatic membrane of artificially differentiated neuroblastoma cells
Neurophysiology - Tập 18 - Trang 154-159 - 1986
Using an intracellular dialysis technique a study was made on calcium and sodium inward currents at the neuroblastoma somatic cell membrane in suspension and during the course of artificial morphological differentiation produced by raising the pH of the culture medium to 8.0–8.2. The density of sodium currents in the somata of cells cultured in the suspension averaged 7.3±0.8 µA/µF, while this val...... hiện toàn bộ

Binocular interaction in the parastriatal rat cortex during a change in intensity of one monocular stimulus
Neurophysiology - Tập 5 - Trang 98-101 - 1973
Binocular interaction in symmetrical centers of the parastriatal cortex in rats was investigated by the evoked potentials method before and after callosotomy. A model was used in which one eye was always stimulated by flashes of average intensity and the other by flashes of average intensity. The presence of contralateral and ipsilateral facilitation, increasing with the strength of the stimulus, ...... hiện toàn bộ
Thresholds and latencies of retinal ganglion cell responses in cats to local stimulation of various parts of their receptive field
Neurophysiology - Tập 3 - Trang 481-485 - 1971
Depending on their responses to separate stimulation of the center and periphery of the receptive field, all ganglion cells of the cat retina can be subdivided into two types: ON-center (OFF-periphery) and OFF-center (ON-periphery). By all the parameters studied these ON- and OFF-systems were symmetrical. This apparently reflects, first, the equality of informativeness of illumination and darkenin...... hiện toàn bộ
Effects of applying oxytocin to Helix pomatia neurons. II. Hyperpolarization
Neurophysiology - Tập 20 - Trang 483-488 - 1988
The ionic mechanisms of hyperpolarization produced by applying oxytocin (OT) were investigated at the membrane of identifiedHelix
pomatia neurons. Two types of neuron were known to exist, in one of which hyperpolarization is produced by a reduction in chloride ions at the membrane and a rise in membrane permeability to potassium ions in the other. In the first of these, response to OT had a revers...... hiện toàn bộ
Interrelations between the contents of transmitter amino acids in the brain structures and the level of convulsion readiness in rats
Neurophysiology - Tập 31 - Trang 395-398 - 1999
In rats with high and low levels of the audiogenic excitability (68 and 62 animals, respectivels, we measured the thresholds of convulsive reactions elicited by electrical stimulation of a few limbic and brainstem structures. The obtained figures were compared with the those of the levels of transmitter amino acids (glutamate, aspartate, glycine, and taurine) measured in the same brain structures ...... hiện toàn bộ
Local changes of resistance in the retinal horizontal cell evoked by changes in membrane potential
Neurophysiology - Tập 5 - Trang 334-341 - 1973
A steady current (10·10−10–6·10−9 A) was passed by means of a bridge circuit through a recording microelectrode inserted into a horizontal cell of the turtle retina. Illumination of the retina caused an increase in the resistance of the microelectrode circuit (by 10–80 MΩ), causing a change in the shape of the recorded response of the horizontal cell to light. The change in resistance was shown to...... hiện toàn bộ
