A mesh microelectrode array for non-invasive electrophysiology within neural organoids

open access: yesbioRxiv, 2020
Organoids are emerging in vitro models of human physiology. Neural models require the evaluation of functional activity of single cells and networks, which is best measured by microelectrode arrays. The characteristics of organoids clash with existing in

Microelectrode recordings in human epilepsy: a case for clinical translation

open access: yesBrain Communications, 2020
With their ‘all-or-none’ action potential responses, single neurons (or units) are accepted as the basic computational unit of the brain. There is extensive animal literature to support the mechanistic importance of studying neuronal firing as a way to ...

Fabrication of Implantable, Enzyme-Immobilized Glutamate Sensors for the Monitoring of Glutamate Concentration Changes in Vitro and in Vivo

open access: yesMolecules, 2014
Glutamate sensors based on the immobilization of glutamate oxidase (GlutOx) were prepared by adsorption on electrodeposited chitosan (Method 1) and by crosslinking with glutaraldehyde (Method 2) on micromachined platinum microelectrodes.

Differential Levels of Glutamate Dehydrogenase 1 (GLUD1) in Balb/c and C57BL/6 Mice and the Effects of Overexpression of the Gene on Glutamate Release in Striatum

open access: yesASN Neuro, 2011
We have previously shown that overexpression of the Glud1 (glutamate dehydrogenase 1) gene in neurons of C57BL/6 mice results in increased depolarization-induced glutamate release that eventually leads to selective neuronal injury and cell loss by 12 ...

AC Electrothermal Effect in Microfluidics: A Review

open access: yesMicromachines, 2019
The electrothermal effect has been investigated extensively in microfluidics since the 1990s and has been suggested as a promising technique for fluid manipulations in lab-on-a-chip devices.
