A video establishes time.
The local stimulus is prepared as a sequence of model events. Every later view refers back to this common temporal axis.

From stimulus
to predicted response.
TRIBE Subcortex is an experimental research workflow built around TRIBE v2 for inspecting video driven cortical predictions and seven subcortical regions. Its central question is temporal: how do modeled response patterns change as a stimulus unfolds?

RESEARCH BOUNDARY
Predicted, not measured.
This workflow estimates brain response from a model. It does not record a person's activity, identify a mental state, or directly measure a neurotransmitter.

One stimulus, two prediction views, and a shared time axis. This diagram shows the workflow, not the outcome of a run.
TRIBE predicts a response.
Cortical surface and experimental subcortical predictions are generated from the stimulus. They are modeled signals, not a recording from the viewer.
Two views resolve into regions.
The cortical view stays alongside the experimental subcortical view. In the latter, predicted voxels are grouped by seven anatomical ROI masks, each yielding a mean absolute activity series.
Patterns return to the event.
Regional series and composite proxies can be compared across chosen windows and inspected for peak timing.

Seven regions.
A closer look.
Select a region to explore its location, anatomical context and place in the analysis. Each prediction channel refers back to the same stimulus timeline.
NACCAccumbens
Selected region / NACC
Accumbens
- Location
- At the ventral meeting point of the caudate and putamen, toward the front and base of the striatum.
- Anatomical context
- Part of the ventral striatum, involved in motivation, reinforcement and reward-related learning.
- In the analysis
- Follow the accumbens prediction channel alongside stimulus events and the other striatal regions. Its modeled magnitude does not measure pleasure or dopamine.
One method, seven channels.
At each timestep, the workflow takes the mean of the absolute model predictions within the selected ROI. The same calculation applies to all seven regions. This illustration explains the anatomy; it does not display a model result.

ROI × TIME
Regional time series
timestep · region · mean |prediction|
Each subcortical ROI yields a time series of summarized prediction magnitudes, aligned to the stimulus timeline.
GROUPED SIGNALS
Composite proxies
ROI series · grouping · composite
Related ROI series can be grouped into readable research proxies. These are model summaries, not direct measures of emotion or dopamine.
WINDOWS
Period comparison
window A · window B · difference
Two user-chosen periods of the same video can be compared by their predicted response magnitude, difference and ratio.

A peak table locates when each composite reaches its highest modeled value within the analyzed clip.
