From the Interface

A group of 5 implantable brain computer interface (BCI) startups, including Musk’s Neuralink, are starting to pull in hundreds of millions of venture capital dollars. While Neuralink has attracted the…

This post compares two new research papers that use generative AI techniques to ‘read’ images and text from human brain activity patterns. The first paper generates sentences that subjects heard in…

Electrical stimulation of the Vagus nerve to treat chronic disease has been around for 35 years, with mixed success. Fifteen ventures, as many therapeutic areas, and billions of dollars later, a new…

Chinese brain-computer interface research is about a decade behind the US or Europe but is likely to catch up quickly as the government pours funding into the China Brain Project. Local manufacturers…

The US Defense Advanced Research Projects Agency invests millions in brain-computer interface projects every year, effectively driving the BCI research agenda. This post catalogs the various programs…

This post reviews the significant milestones in the development of neural dust and lays out the state of the art in 2020. The neural dust device is 3 millimeters long and 1×1 millimeters in cross…

All BCI devices record. Only a few of them provide direct feedback to the brain in real-time. This post lists current closed-loop human BCI devices and their applications. X-rays from patients…

Can following the money tell us about the interface between academic research and venture-funded companies in BCI. Is there a clear boundary at all? What does the 'funding lens' reveal, about who is…

From neurons in dishes to behaving insects to primates, how do we trade off accessibility and iteration speed against clinical relevance? What model is best suited to which research question? Photo a…
