# Reverse Brain Encoder
**Entity class:** Computational neuroscience concept
**Domain:** Neuroimaging / Machine learning
**Maturity:** Developed
## Definition
A reverse brain encoder predicts how measured brain regions would respond to an input image or other stimulus.
## Mechanism and significance
In Brain-IT, the reverse pathway supplies additional predicted fMRI examples, turning a limited paired dataset into a larger self-supervised learning system.
