Neural network models of cortical functions based on the computational properties of the cerebral cortex [0.03%]
基于大脑皮层计算属性的大脑皮质功能神经网络模型研究进展

E Guigon et al.
We describe a biologically plausible modelling framework based on the architectural and processing characteristics of the cerebral cortex. Its key feature is a multicellular processing unit (cortical column) reflecting the modular nature of...
A behavioral and electrophysiological study of the comparison of size-discrepant shapes [0.03%]
大小不一的形状比较的行为学和电生理学研究

A Pierret
An experiment was performed to find an electrophysiological correlate of the way objects of different sizes are perceived as identically shaped. The subjects were presented with pairs of geometrical figures and were instructed to decide whe...
Distribution and metabolism patterns of plasma 7S- and beta-NGF in the adult male rat [0.03%]
成人雄性大鼠血浆7S和β-NGF的分布与代谢模式研究
P Pradier,I Jalenques,M Dalle et al.
P Pradier et al.
There is a great deal of controversy on the existence of NGF in body fluids and tissues. To date it remains unknown whether this peptide accumulates preferentially at significant levels in different organs. Thus we undertook the evaluation ...
Effect of subthalamic high frequency stimulation on substantia nigra pars reticulata and globus pallidus neurons in normal rats [0.03%]

Effect of resiniferatoxin on stimulated gastric acid secretory responses in the rat [0.03%]
树脂毒素对大鼠刺激胃酸分泌反应的影响
O M Abdel-Salam,J Szolcsányi,G Mózsik
O M Abdel-Salam
The effect of the capsaicin analogue 'resiniferatoxin' (RTX) was studied on basal and stimulated gastric acid secretory responses following sc bethanechol (1.5 mg/kg), sc pentagastrin (50 micrograms/kg) and sc histamine (0.5 and 2.5 mg/kg) ...
Nitric oxide reduces the thermogenic changes induced by lateral hypothalamic lesion [0.03%]
一氧化氮可减弱侧脑室旁核损伤所致的产热变化
M Monda,S Amaro,A Sullo et al.
M Monda et al.
The experiment described here tests the effect of intracerebroventricular (icv) injection of nitric oxide (NO) precursors, such as L-arginine (L-arg) and nitroprusside (NP), on the thermogenic changes induced by lesion of the lateral hypoth...
The Maudsley rat strains as a probe to investigate noradrenergic-cholinergic interaction in cognitive function [0.03%]
莫德斯雷大鼠品系作为探究去甲肾上腺素-胆碱能交互作用在认知功能中的探针
S J Sara,V Devauges,A Biegon et al.
S J Sara et al.
Central noradrenergic function in relation to cognitive performance was studied in the Maudsley rat strains. Neurochemical studies revealed a higher response to acute stress in the locus coeruleus (LC) in the Maudsley reactives (MR) than in...
Calcium binding sites of the transmitter release mechanism: clues from short-term facilitation [0.03%]
短时程突触强化揭示的神经递质释放机制钙结合位点
Y Liu,E F Stanley
Y Liu
The binding of multiple, probably four, calcium ions to an intraterminal protein is believed to be an integral step in the gating of neurotransmitter release. We have reexamined the clues to this ion-protein interaction inferred from experi...
The role of non-quantal release of acetylcholine in regulation of postsynaptic membrane electrogenesis [0.03%]
乙酰胆碱非量子化释放对突触后膜电位发生机制的调节作用
F Vyskocil,E E Nikolsky,H Zemková et al.
F Vyskocil et al.
In mammalian nerve-muscle preparations treated with an anticholinesterase, the acetylcholine (ACh) released non-quantally (NQR) reaches the postsynaptic receptors and causes a small depolarization of the membrane potential at the endplate r...
Mediatophore and other presynaptic proteins. A cybernetic linking at the active zone [0.03%]
媒介质囊泡和其他突触前蛋白。活性区的控制论连接

Y Dunant
In rapidly transmitting synapses, the mediatophore, a protein located in the presynaptic membrane, seems to play a key role in the last step of transmitter release. Reconstituted either in proteoliposomes or in Xenopus oocytes, or transfect...
