visual data

How does our brain organize the visual information that our eyes capture? Researchers at the University of California, Berkeley, used computational models of brain imaging data to answer this question and arrived at what they call “continuous semantic space” – a notion which serves as the basis for the first interactive maps showing how the brain categorizes what we see.The data on which the maps are based was collected while the subjects watched movie clips. Brain activity was recorded via functional Magnetic Resonance Imaging (fMRI), a type of MRI that measures brain activity by detecting related changes in blood flow. In order to find the correlations in the data collected, the researchers used a type of analysis known as regularized linear regression...
