An MIT researcher seized his dog Jackie's veterinary MRI sessions to collect fMRI + wireless EEG + vitals across six sessions, including social conditions (stray dog: HR 124 bpm, bilateral amygdala activation; best friend: balanced response; familiar neighbor: HR 98). Using pure Python—no deep learning frameworks—he built an open-source digital twin with a 6-dimensional emotion vector and 25-region activation map, openly admitting it's a simplified linear approximation yet one whose outputs match the real scans.
