MRI Research

The ACT-R research group uses fMRI studies to confirm and improve cognitive models. We conduct studies at the Brain Imaging Research Centre and at the UPMC Presbyterian.

For our studies, we warp participant brains to a reference brain we scanned most recently in 2005. This is available for download below as a T1-weighted Analyze-format image.
