Welcome to the pycortex WebGL MRI viewer! This viewer shows how information about thousands of object and action categories is represented across human neocortex. The data come from brain activity measurements made using fMRI while a participant watched hours of movie trailers. Computational modeling procedures were used to determine how 1705 distinct object and action categories are represented in the brain. Further details on this work can be found in this video or in the paper by Huth, Nishimoto, Vu and Gallant (2012), "A continuous semantic space describes the representation of thousands of object and action categories across the human brain", Neuron 2012. If you have problems, email us. Warning:This page uses WebGL, an experimental web technology. Instructions: On the left is a 3D model of one participant's cortical surface. Hints: The 3D viewer will run much faster if the ROI labels are disabled. Credits: The pycortex WebGL MRI viewer was written by James Gao.
