    I could never convey the feeling of this discovery: itโ€™s a random Tuesday and, all of a sudden, we saw a branching, treelike structure. Moreover, itโ€™s my own brain. A brain was looking at itself, while also knowing that it was the first time anyone in the world had seen this

    We recently obtained the highest-resolution 3D images of the human brain ever taken from outside the skull. This is the first look. Introducing Aleph, a research lab building brain interfaces for the telepathic future. (1/n)

    Can we invent new brain-computer interface modalities? @raffi_hotter and I got 9 friends together and built a lab at home to test two totally new imaging methods: acoustoelectric imaging & functional ultrasound through the skull ๐Ÿงต story that involves nV measurements, pretty

    .@raffi_hotter and I ran a 2-week hackathon investigating whether you could decode images from a portable brain scanner We got initial results that suggest you can reconstruct images like these from brain activity recorded with time-domain NIRS, and share our detector prototype

    The most cowboy path to BCI: spectral hole burning + ultrasound-modulated optical tomography First apply ultrasound and light: the ultrasound tags photons that pass through a location on the brain with a small (1 MHz) color shift. Then โ€” *cryogenically* cool a crystal to 4 K and

    We pursued acoustoelectric imaging and functional ultrasound since, in principle, you can get 1-mm resolution brain readings noninvasively. Compared to EEG, thatโ€™s ~10,000x the number of channels!

    It was exhilarating to wake up and constantly be thinking about the science, in an airbnb with friends - making our own acoustic lenses out of candle wax, Orbeez, and carved... carrot molds - new levels of jank, duct taping hydrophones to plastic straws - buying 27 gallons of

    Acoustoelectric imaging (AE) uses a physical phenomenon where ultrasound interacts with electric fields Functional ultrasound was recently shown with the skull removed, but has yet to be shown with the skull intact

    In the acoustoelectric effect, ultrasound interacts with electric fields by changing the conductivity of a material. By applying ultrasound to a region, you can isolate signals from that region by looking for modulation at the ultrasound frequency โ€” typically > 500 kHz.

    We decided to measure it ourselves. Turns out you can buy a human skull online from skullsunlimited.com...
