UnverifiedThe stimulus processing pipeline of this digital twin is roughly as follows: StimulusMapper first matches a real session, applies the emotion increment obtained by averaging real BOLD and EEG values, each region decays toward baseline and then BOLD is injected from the matched session, special social enhancement is added for the three dog conditions, the heart rate is updated to the actual measured value, and everything is stored in a memory buffer.69% similar
