Review Argues DBS, BCIs, and Speech Neuroprostheses Share a Common Translational Bottleneck

Summary

A review by Volodymyr Mavrych, Olena Bolgova, Leen Alhamd, and Rasha Alissa of Alfaisal University and Sulaiman Alrajhi University surveys the current state of implantable neurotechnology, spanning deep brain stimulation, brain-computer interfaces, and speech neuroprostheses. Rather than treating these as separate fields, the authors frame all three as variations on the same basic engineering pipeline — picking up a neural signal, interpreting it, acting on it, keeping the hardware powered and communicating, and proving over time that it holds up clinically. Their central claim is that what's actually slowing these technologies down is friction at those shared checkpoints, not problems specific to any one device category, and they trace how implant design, surgical technique, and clinical use cases have shifted as the field has matured.
