Functional magnetic resonance imaging (fMRI) was used to measure brain activity in seven people while they listened to more than 2 hours of stories from The Moth Radio Hour. This data was used to estimate voxel-wise models that predict brain activity in each voxel (volumetric pixel) based on the meaning of the words in the stories. Read the paper describing this research here.

This is an interactive 3D viewer for models fit to one subject’s brain. Colors show the category of words predicted to elicit the largest response in each voxel (legend, bottom left).
