“Mind Reading,” pages 261 – 269.!
Depend on having a good understanding of how vision is process in the brain, but also shows fMRI technique. In a
nutshell, had participants watch a movie and then could reconstruct what they watched from looking at the fMRI. Know a lot about how visual cortex responds to
a lot of these features. Not the ﬁrst study to do
this, but different in that went from looking at
static images to moving images. The challenge
is that the BOLD reading is delayed. Have to
know certain things about the brain already for
A. The hemodynamic response (HRF) at each voxel in the visual cortex for unknown movie V1, V4 areas do. The fusiform-face
ex, what the clips.
Can the observed signal be decoded to reconstruct the movie the subjects were watching?! a larger area than some other
areas. So reconstructions can only be so good
because the poxels contains millions of the
neurons so can't dete...
