Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The mode of Na+ entry and the dynamics of intracellular Na+ concentration ([Na+]i) changes consecutive to the application of the neurotransmitter glutamate were investigated in mouse cortical astrocytes in primary culture by video fluorescence microscopy. ...
Recently, it has been shown that correct trafficking of neuronal plasma membrane receptors along the endosomal pathway is directly implicated in molecular mechanisms underlying synaptic plasticity and is fundamental for proper neuronal communication. To un ...
Glutamatergic neurotransmission is associated with release of arachidonic acid (AA) from membrane phospholipids of both neurons and astrocytes. Since free AA has been shown to enhance glutamate-mediated synaptic transmission, it can be postulated that glut ...
Therapeutic value of the alkylating agent ifosfamide has been limited by major side effects including encephalopathy. Although the underlying biochemical processes of the neurotoxic side effects are still unclear, they could be attributed to metabolites ra ...
The effects of inhibitors of the glial Na+/glutamate co-transporter on the intracellular Na+ concentration (Na+) were investigated in mouse cortical astrocytes. Na+ was monitored by fluorescence microscopy on single astrocytes using the Na+-sensi ...
We quantified the effect of the excitatory amino acids kainate and glutamate on the uptake of cobalt in primary rat cerebellar granule neurons, by using inductively coupled plasma-atomic emission spectroscopy (ICP-AES). We quantitatively demonstrated that ...
BACKGROUND: Deep hypothermia has been associated with an increased incidence of postoperative neurologic dysfunction after cardiac surgery in children. Recent studies suggest an excitotoxic mechanism involving overstimulation of glutamate receptors. Extrac ...
Conventional intracellular recordings were used to monitor postsynaptic potentials of basolateral amygdala neurones (BLA) in brain slices comprising the BLA, the entorhinal cortex (EC) and the hippocampus, in which the EC-BLA connections were preserved. St ...
Cultured mouse cortical astrocytes of the stellate type were studied by using the patch-clamp technique in whole-cell configuration. The astrocytes express at least two types of outwardly rectifying K+ channels which mediate a transient and a sustained cur ...
Excitatory synaptic transmission is associated with changes in both extracellular and intracellular pH. Using mouse cortical neurons in primary cultures, we studied the sensitivity of glutamate-evoked release of 3H-arachidonic acid (3H-AA) to changes in ex ...
