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.
We present a simple and easy to handle PDMS microfluidic device for neuronal cell culture studies in three-dimensional hydrogel scaffolds. The hydrogel is structured in parallel layers to reconstruct cell layers close to the natural environment. Dissociate ...
Abstract—Mapping neuronal networks activity of in-vitro cell cultures with microelectrode array (MEA) based systems, providing a spatial resolution down to cellular/sub-cellular levels and an adequate temporal resolution for resolving action potential prop ...
The complexity of processes occurring in the brain is an intriguing issue not just for scientists and medical doctors, but the humanity in general. The cortex ability to perceive and analyze an enormous amount of information in an instance of time, the par ...
We present a 3-D microfluidic device designed for localized drug delivery to cellular networks. The device features a flow cell comprising a main channel for nutrient delivery as well as multiple channels for drug delivery. This device is one key component ...
Hyperphosphorylated tau makes up the filamentous intracellular inclusions of several neurodegenerative diseases, including Alzheimer's disease(1). In the disease process, neuronal tau inclusions first appear in the transentorhinal cortex from where they se ...
Extra-cellular matrix (ECM) tethered morphogen gradients play an important role in tissue development and regeneration. There is currently only a limited set of model systems which can mimic these gradients in an artificial ECM-like environment. We have de ...

Despite the importance of the aberrant polymerization of A beta in the early pathogenic cascade of Alzheimer's disease, little is known about the induction of A beta aggregation in vivo. Here we show that induction of cerebral beta-amyloidosis can be achie ...
Alzheimer's disease presents morphologically with senile plaques, primarily made of extracellular amyloid-beta (A beta) deposits, and neurofibrillary lesions, which consist of intracellular aggregates of hyper-phosphorylated tau protein. To study the in vi ...
By enhancing the environment of micro electrode arrays with microfluidic channels we cultured primary neuronal cells in patterned two- and three dimensional structures. Alternatively, the same microfluidic channels can be used to generate a local chemical ...
The correlation between neurodegenerative disease and protein aggregation in the brain has long been recognized, but a causal relationship has not been unequivocally established, in part because a discrete pathogenic aggregate has not been identified. The ...
