Analysis Highlights
Load an analysis to see key neural moments.
Prediction Accuracy vs. Baselines (Pearson r)
Encoding models evaluated on held-out subjects. TRIBEv2 significantly outperforms linear models and prior brain scan baselines on speech and movie stimuli (Pearson r, higher is better).
In-Silico Neural Stimulation
What It Means
TRIBEv2 simulates what changes to your video — edits, cuts, music, copy — would increase predicted brain engagement, without re-filming.
How Cerevra Uses It
The WHY analysis and recommendations are grounded in in-silico experiments — identifying which content elements drive the highest cortical engagement.
Key Capability
Gradient-based optimization through the fMRI encoding model computes which content direction maximises activation in target brain regions (reward circuit, memory, attention).
