Modulation by Nitric Oxide (NO) of the Intensity of Non-Quantum Mediator Secretion in Neuromuscular Junctions in RatsSpringer Science and Business Media LLC - Tập 31 - Trang 451-455 - 2001

Experiments on rat diaphragm muscle showed that the nitric oxide (NO) donors sodium nitroprusside (SNP) and S-nitroso-N-acetylpenicillamine (SNAP), as well as L-arginine, a substrate for NO synthesis, decreased the level of muscle fiber hyperpolarization (the H effect) after blockade of cholinoceptors on the postsynaptic membrane by d-tubocurarine in conditions of irreversible inhibition of acetyl...... hiện toàn bộ
Correlation between alerting rhythm and unit activity in the rabbit thalamusSpringer Science and Business Media LLC - Tập 5 - Trang 127-131 - 1972

The alerting rhythm, regular electroencephalographic (EEG) waves with a frequency of 4–10/sec arising simultaneously in several structures of the rabbit's brain, is seen during orienting, defensive and food-seeking behavior (1, 2, 4, 6, 7, 9). Questions of interest have to do with the topography of its spread through different brain structures and with the location of structures in which it is act...... hiện toàn bộ
Characteristics of the Actions of Neurotensin on Motor Reactions in Rats in Response to Positive and Negative Conditioned SignalsSpringer Science and Business Media LLC - Tập 34 - Trang 299-302 - 2004
N. P. Shugalev, N. G. Yamshchikova, A. S. Ol'shanskii, A. V. Stavrovskaya
This study addressed the effects of microinjections of neurotensin into the caudate nucleus and substantia nigra on the performance of motor reactions in response to positive and negative conditioned signals, as well as the post-effects of microinjections in subsequent experiments. Neurotensin had positive effects on the extinction of non-reinforced motor reactions. Neurotensin had no effect on th...... hiện toàn bộ
Role of von Economo and fork neurons in the evolution of vocal learningSpringer Science and Business Media LLC - Tập 53 - Trang 695-706 - 2023
Shubha Srivastava
The present review presents a new and feasible assumption in the comparative neurobiology of vocal production learning that underpins human speech. Vocal learning, the competence of modulating acoustic sounds or imitating novel sounds, is a requisite requirement of human spoken language and is considered a major innovation for the evolutionary origin of human verbal communication. Having numerous ...... hiện toàn bộ
