WebWe trained a VAE with a five-layer encoder and a five-layer decoder to learn visual representations from a diverse set of unlabeled images. Using the trained VAE, we predicted and decoded cortical activity observed with functional magnetic resonance imaging (fMRI) from three human subjects passively watching natural videos. WebNov 4, 2024 · fMRI measures brain activity by tracking changes in blood flow to the brain. fMRI is derived from structural MRI. In fact, they both use the same machine, called a magnetic resonance scanner ( Figure 1 ). MRI technology is used to create detailed, 3D images of the internal structure of an object using magnetic fields and radio waves [ 1 ].
WebfMRI allows experimental designs that resemble those used in psychology laboratories. fMRI is a more accurate way to localize activity. fMRI does not require exposure to radiation. fMRI localizes changes in activity over briefer periods than does PET. fMRI is a more accurate way to localize activity.
