Elon Musk has been in the press lately for the work his company Neuralink is doing to accelerate the development of brain-machine interfaces (BMIs). BMIs use imaging technology to decode mental and emotional brain states. For example, a BMI could decode that you want to send a text message to your friend Robin to ask her about her new job, and automatically do it without you ever touching your phone. A more advanced BMI could sense how you want a PowerPoint slide to look and automatically create it and put it in a business presentation.
The core technology of a BMI relies on interpreting and decoding brain signals, typically either blood flow or neural activity. Dynamic Light has demonstrated that Speckle imaging is a promising way to measure blood flow during surgery when the tissue
But what about when tissue is not exposed?
Co-founders Andrew Dunn and David Miller recently presented thier work on the future of Speckle imaging to measure blood flow through tissue. This would be akin to a MRI scan, but without needing a huge magnet. Speckle imaging offers the ability to measure brain states non-invasively; imagine a ski hat outfitted with lasers and camera sensors. These types of devices will likely follow after the more invasive electrode devices that Elon Musk and Neuralink are working on. The ability to measure brain states without invasive electrodes has much broader applications for use in everyday life.
