The image to the right of the word neuron was taken from someone’s brain.
To be a bit more specific an individual looked at the black and white image of the word neuron (see the top image) while receiving an fMRI brain scan. A computer then crunched through the data from the scan and produced the series of slightly garbled images. The images are not of an incredible resolution but nonetheless they still show clearly the image that the individual tested was looking at. Thus in a very real way the researchers were able to produce a physical picture of a mental image.
This story broke back in December but it’s so impressive it’s worth mentioning three months later.
