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 high complexity of cortical convolutions in humans remains a mystery for both engineers to measure and compare it, and for biologists to understand it. We developed a method for the quantification of the cortical area allowed by the process of folding. ...
The distribution of vasoactive intestinal peptide binding sites in the rat brain was examined by in vitro autoradiography on slide-mounted sections. A fully characterized monoiodinated form of vasoactive intestinal peptide (M-[125I]VIP) previously shown to ...
Neurotransmitter-specific anatomical techniques have provided a tool to define the morphological constraints within which a given neurotransmitter will exert its cellular actions. Biochemical and electrophysiological approaches have revealed the nature of ...
We propose an alternative paradigm for processing time-varying visual inputs, in particular for tasks involving temporal and spatial integration, which is inspired by hypotheses about the computational role of cortical microcircuits. Since detailed knowled ...
The distribution of vasoactive intestinal peptide (VIP) binding sites in the brain of several vertebrate species was examined by in vitro autoradiography on slide-mounted sections. This study included fish, frog, snake, pigeon, rat, mouse, guinea pig, cat ...
K+, at concentrations reached in the extracellular space during neuronal activity (5-10 mM), promotes a time- and concentration-dependent hydrolysis of [3H]glycogen newly synthesized by mouse cerebral cortical slices. In the present study, the glycogenolyt ...
A growing number of biologically active peptides is being identified within the central nervous system (CNS). According to currently accepted criteria, several of these peptides, including VIP, can be viewed as neurotransmitters. Recent immunohistochemical ...
Distribution of the monocarboxylate transporter MCT1 has been investigated in the cortex of normal adult human brain. Similarly to the glucose transporter GLUT1 55 kDa isoform, MCT1 was found to be strongly expressed on blood vessels in all cortical layers ...
The role of lactate in brain energy metabolism has recently received renewed attention. Although blood-borne monocarboxylates such as lactate poorly cross the blood-brain barrier in the adult brain, lactate produced within the brain parenchyma may be a sui ...
The glycogenolytic action of norepinephrine (NE) was examined in the tottering mouse, a spontaneously epileptic mutant which presents a noradrenergic hyperinnervation of various CNS areas, including the cerebral cortex. The potency and efficacy of NE in pr ...
