When I post about mindreading, it is usually about perceptions of what is going on in the mind based on external behavior. But there has been huge progress in brain scans understanding coarse brain activity. Neurokeptic
reports:
A neat paper from Schoenmakers et al of the Dutch Donders Institute reports on Linear reconstruction of perceived images from human brain activity
It introduces a new mathematical approach for decoding (or ‘brain reading’) the image that someone is looking at, pixel-by-pixel, based on the pattern of neural activity in their visual cortex.
The paper claims to reconstruct letters from brain scans, as shown below.
