Study Predicts Sexual Orientation from Brain Connectivity Patterns
- Used resting-state fMRI and machine learning to predict sexual orientation with 82.9% accuracy for homosexuals and 100% for heterosexuals
- Identified 5 brain regions that accurately predicted orientation 4 frontal lobe regions and the right precuneus cortex
- Precuneus is connected to regions that process sexual stimuli and arousal
- Results don't address what caused the brain differences between groups
- Demonstrates that sexual orientation can be predicted by brain connectivity measures using AI, but doesn't explain origins of orientation
