Research update

Advancing neurotech from brain surface to brain depths

New research into higher-density neural probes, more extensive electrode coverage of the brain surface, and electrical stimulation ability.

Summary

This article highlights recent advancements in neurotechnology, presented in three papers at the 2024 VLSI Circuits Symposium.

A new high-density readout IC for multiplexed channels allows for large-scale recordings of brain-surface activity.

Imec’s latest neural probe for deep-brain recordings features a record-high channel count and improved performance compared to the state of the art.

A novel technique to suppress stimulation artifacts in brain recordings holds promise for combined stimulation/recording implants.
