Brain Imaging Simulator (2D)

Neuroimaging techniques such as MRI, CT, fMRI and PET let clinicians and researchers see inside a living brain without surgery. This 2D companion visualizes both halves of that story on a single cross-sectional brain slice: a structural mode sweeps a scan line through the tissue, the way a real scanner builds a cross-sectional image, while a functional mode overlays a simulated BOLD activity signal across a handful of cortical regions, thresholded the way a real fMRI analysis pipeline draws an activation map. Switch scan mode and imaging plane, and tune scan speed, activity threshold and task-paradigm frequency to see how each changes what the scan reveals.
