Ultrasound brain imaging achieves most detailed vascular image of living human brain through skull
By

Summary
The article discusses a breakthrough in brain imaging using ultrasound technology through the skull, presenting the most detailed vascular image of a living human brain ever captured. It contrasts this approach with the limitations of fMRI (which requires large, immobile MRI machines) and invasive brain-computer interfaces (which require drilling into the skull). The piece explores how ultrasound imaging could serve as a middle ground — non-invasive yet high-resolution — for mind interfacing and brain activity decoding, building on earlier research that reconstructed images from brain activity using fMRI.

It's wild and shows just a glimmer of what a telepathic future would be like.
Unfortunately, it requires an MRI machine, which sadly can't be worn on the head.
The first bottleneck to the whole field of mind interfacing is the hardware. There are currently two extremes: drill a hole through your skull and stick electrodes in, or use non-invasive techniques that are much lower resolution.
