This study introduces a 256-channel microelectrode array (MEA) system for simultaneous neural recording and stimulation. The integrated electronics enable independent control of all channels, advancing neural network research.

Area of Science:

  • Neuroscience
  • Bioelectronics
  • Microelectronics Engineering

Background:

  • Understanding large neural networks requires simultaneous recording of many neurons.
  • Microelectrode arrays (MEAs) are used for neural recording, with microfabrication enabling higher densities.
  • Conventional electronics face limitations in scaling up electrode counts and independent channel control for high-density MEAs.

Purpose of the Study:

  • To present a novel 256-channel in vitro MEA system with integrated electronics.
  • To enable simultaneous recording and stimulation of neural networks with independent channel control.

Main Methods:

  • Development of a 256-channel microelectrode array (MEA) using microfabrication technologies.
  • Integration of electronics for simultaneous neural recording and stimulation.
