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.
In view of the neurotrophic effect of vasoactive intestinal peptide (VIP), the regulation of brain-derived neurotrophic factor (BDNF) expression by VIP and the related peptide pituitary adenylate cyclase-activating polypeptide (PACAP) was analysed by North ...
Dual voltage recordings were made from pairs of adjacent, synaptically connected thick tufted layer 5 pyramidal neurones in brain slices of young rat (14-16 days) somatosensory cortex to examine the physiological properties of unitary EPSPs. Pre- and po ...
Although signaling between neurons is central to the functioning of the brain, we still do not understand how the code used in signaling depends on the properties of synaptic transmission. Theoretical analysis combined with patch clamp recordings from pair ...
We have investigated the modulatory action of excitatory amino acids (EAA) on vasoactive intestinal polypeptide (VIP)-stimulated cAMP formation in mouse cerebral cortical slices. Glutamate and aspartate potentiate in a concentration-dependent manner the ef ...
VIP neurons are a homogeneous population of intracortical bipolar cells. They receive excitatory synapses from afferent circuits to the cortex and exert effects on neurons, astrocytes, and capillaries. Effects on the two latter cell types imply that VIP ne ...
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 ...
The entorhinal cortex is a gateway to the hippocampus; it receives inputs from several cortical associative areas as well as subcortical areas. Since there is evidence showing that noradrenaline reduces the epileptic activity generated in the entorhinal co ...
What is the nature of the cellular actions of VIP (vasoactive intestinal polypeptide) in the neocortex? Is VIP co-localized with another neurotransmitter? Do VIP neurons interact with other cortical neurotransmitter systems? How does the intracortical VIP- ...
The excitatory amino acid glutamate was previously shown to stimulate aerobic glycolysis in astrocytes by a mechanism involving its uptake through an Na+-dependent transporter. Evidence had been provided that Na+,K+-ATPase might be involved in this process ...
