What Does a Microelectrode Array Do?

Microelectrode arrays captures the field potential

or activity across an entire population of cells, with far greater data points per well, detecting activity patterns that would otherwise elude traditional assays such as patch clamp electrophysiology which probes a single cell such as a neuron.

What are microelectrode arrays used for?

Microelectrode arrays and microprobes have been widely utilized to measure neuronal activity, both in vitro and in vivo. The key advantage is the capability to record and stimulate neurons at multiple sites simultaneously.

What is the function of a microelectrode?

Microelectrodes are used during electrophysiology experiments to record electrical activity from neurons, but they can also be used to deliver electrical current into the brain or to neurons in culture in a process called microstimulation.
