Abstract
Neuronal electrical properties are often aberrant in neurological disorders. Human induced pluripotent stem cells (hiPSCs)-derived neurons represent a useful platform for neurological disease modeling, drug discovery and toxicity screening in vitro. Multi-electrode array (MEA) systems offer a non-invasive and label-free platform to record neuronal evoked-responses concurrently from multiple electrodes. To better detect the neural network changes, we used the Axion Maestro MEA platform to assess neuronal activity and bursting behaviors in hiPSC-derived neuronal cultures. Here we describe the detailed protocol for neuronal culture preparation, MEA recording, and data analysis, which we hope will benefit other researchers in the field.
