movie clip. Then, 18 million seconds of movie clips were sampled from the internet and applied to the voxel-based
encoding models to produce a predicted HRF for each of the 18 million clips. ! The movie based solely on the brain activity from the visual cortex! https://www.youtube.com/watch?v=nsjDnYxJ0bo!
Example of an image they were able to reconstruct based on their brain activity alone. A lot of cognitive neuroscience has been trying to
create and study something like this for many years. Looking in a voxel basis (like 1 million neurons in one space) yet still able to construct
this. The pattern of BOLD response in the visual cortex to particular features
in the visual ﬁeld is quite predictable. Therefore, brain activity can be
decoded to infer what a subject is looking at (e.g., a face or a car).! transducing light energy into a neural signal!
the nature of receptive ﬁelds!
multimodal integration! The reason why this study is a good one for this
particular section is b/c the models that they
