Recording 3D neuronal activity on chip with segmented 3D microelectrode arrays

FET-based integrated charge sensing in a MEM organ-on-chip platform

A 3D microelectrode array to record neural activity at different tissue depths

In vitro study of high-level neurobiological systems requires three-dimensional (3D) neuronal cultures [1]. Meas-uring responses along all three spatial dimensions is critical to record electric activity inside 3D neuronal models, such as organoids and other 3D brain tissue constructs. However, this lies beyond the capacity of 2D microelec-trode...
