To advance our understanding of the functioning of neuronal ensembles, systems are needed to enable simultaneous recording from a large number of individual neurons at high spatiotemporal resolution and good signal-to-noise ratio. Moreover, stimulation capability is highly desirable for investigating, for example, plasticity and learning processes. Here, we present a microelectrode array (MEA) system...
An integrated CMOS chip for performing electrochemical experiments, which can continuously monitor the metabolic activity of biological cells, is presented. The chip comprises an array of 1024 platinum working electrodes, 64 current readout channels, an integrated potentiostat with on-chip counter, as well as reference electrodes and a temperature sensor. Two different sigma-delta analog-to-digital...
