FAQ: Reliability-Based Voxel Selection

When researchers measure neural responses using fMRI, they’re often faced with a question: which brain regions should they analyze? There’s no single best answer to this question, but I recently published a paper (with my advisor, Talia Konkle) outlining one approach: selecting the voxels with reliable data. The aim is to restrict your analyses to the parts of the brain that respond consistently over multiple presentations of the same stimuli.
