Very interesting technology, but I think it's still far from being of any practical use.
If anyone is interested, the original paper can be found on Current Biology.
From what I understand they used blood oxygen level-dependent signals measured using fMRI
to train a number of models they had of the possible brain response to the images.
They then used a different set of data for testing the accuracy of the trained models.
Having some insights on how the brain processes images they were able to reconstruct image data using a statistical approach.
The voxels that were mentioned by someone in this thread are not the ones associated with 3D rendering but
are involved in the sampling of data from the fMRI. Voxels are the output of a technique (Statistical parametric mapping) used to statistically
evaluate fMRI results which produces a spatial map of the brain activity.
The paper It's fairly technical in nature, maybe some of you can get a better understanding, the details of the process remain obscure to me but it
makes more sense overall now I think.
