Neural Recording under Electrical Microstimulation
System on a Chip Neural Recording Device
A miniature system on a chip (SoC) device enables continuous, full-duplex neural recording with simultaneous electrical microstimulation. The technology enables precise, closed-loop neuromodulation based on direct neuronal feedback. Scalable and with a small chip area and high channel density, this new design could suppress electrode noise and support high impedance electrodes, especially important to ultra-large-scale recording. The device can be used for a wide spectrum of neurological diseases through closed-loop neuromodulation.
Monitoring Neural Activity under Electrical Stimulation
Current electrical stimulation and recording technologies are not able to “talk to the brain” and “hear from the brain” at the same time. Electrical stimulation has been used for probing neural circuitry and identifying networks of neurons for many years, but investigating and understanding the behavior of neural populations under electrical stimulation requires simultaneously monitoring neural activity, which has not been possible until now. Furthermore, current technologies suffer from limitations of scalability as well as poor signal quality, artifacts and noise prone to misinterpretation. This device is the first technology that allows bidirectional communication with a brain and nervous system and features improvements in power, noise, resolution, size, weight, scale and functionality.
