Postsynaptic Ca2+ changes are involved in control of cellular excitability and induction of synaptic long-term changes. We monitored Ca2+ changes in dendrites and spines during synaptic and direct stimulation using high resolution microfluo...
The metabotropic glutamate receptor (MGR): pharmacology and subcellular location [0.03%]
元谷氨酸受体（mGluR）的药理学和亚细胞定位

F Sladeczek et al.
A pharmacological characterization of the metabotropic glutamate receptor (MGR) was performed in striatal neurons. Among the excitatory amino acid receptor antagonists tested, only D, L-2-amino-3-phosphonopropionate (D, L-AP3) inhibited QA-...
Divalent cation changes in cerebellar Purkinje cells after climbing fiber deafferentation [0.03%]

R T Kado et al.
A secondary ion mass spectrometry (SIMS) microscope was used to detect intracellular stores of calcium, magnesium, sodium and potassium. Measurements were made in semithin sections of fixed tissues of normal and climbing fiber deafferented ...
Presynaptic receptors for FMRFamide, histamine and buccalin regulate acetylcholine release at a neuro-neuronal synapse of Aplysia by modulating N-type Ca2+ channels [0.03%]
FMRFamidergic、组胺能和buccalin能受体通过调节N型Ca2+通道调控海兔神经-神经突触乙酰胆碱的释放
G Baux,P Fossier,L E Trudeau et al.
G Baux et al.
At an identified neuro-neuronal synapse of the buccal ganglion of Aplysia, quantal release of acetylcholine (ACh) is increased by FMRFamide and decreased by histamine or buccalin. Activation of presynaptic receptors for these neuromodulator...
Intracellular Ca2+ stores in neurons. Identification and functional aspects [0.03%]
神经元内的Ca2+库的鉴定及其功能方面

J Meldolesi et al.
Various aspects of the rapidly exchanging intracellular Ca2+ stores of neurons and nerve cells are reviewed: their multiplicity, with separate sensitivity to either the second messenger, inositol 1,4,5-trisphosphate, or ryanodine-caffeine (...

The process of light adaptation in vertebrate rod and cone photoreceptors is believed to involve a diffusible cytoplasmic messenger. Two lines of evidence indicate that photoreceptor light adaptation is mediated by a light-induced fall in c...

Caudal hair cell impulses cause postsynaptic inhibition of ipsilateral type B photoreceptors in the snail Hermissenda. This inhibition is shown to be GABAergic according to a number of criteria. HPLC, mass spectrophotometric, and immunocyto...

Confocal imaging of intracellular Ca2+ brings a new level of resolution to the study of hormonal control of intracellular Ca2+ release. This approach has demonstrated the existence of pulsatile circular and spiral waves of Ca+ release induc...
Charge movement and Ca2+ release in normal and dysgenic foetal myotubes [0.03%]
正常和遗传异常的胎儿肌管中的电荷运动及Ca2+释放

T Shimahara et al.
Intramembrane charge movement and Ca2+ release from sarcoplasmic reticulum was studied in foetal skeletal muscle cells from normal and mutant mice with 'muscular dysgenesis' (mdg/mdg). It was shown that: 1) unlike normal myotubes, in dysgen...
