multi-electrode array

A multi-electrode array (MEA) is a device with many tiny electrodes that can simultaneously record electrical signals from or stimulate multiple neurons or cells in a biological sample, such as brain tissue or cultured neurons. It allows scientists to monitor how groups of cells communicate and respond over time, providing insights into neural activity and network behavior. MEAs are useful in research for understanding brain function, developing neural treatments, or testing drugs, making complex data collection more efficient and comprehensive through multiple, coordinated measurements.
