Researchers found that large language models align with human brain activity during creative thinking tasks, with alignment increasing based on model size and idea originality. Different post-training approaches selectively reshape how LLMs align with creative versus analytical neural patterns in humans.
Researchers have developed a novel framework for comparing Transformer-based AI models by mapping their internal attention topology onto human brain networks, analyzing 151 models across vision, language, and multimodal domains. The study reveals an arc-shaped distribution of topological alignment with human cognition, where models trained for semantic abstraction align with higher-order brain networks, while detail-focused models align with low-level networks, though alignment scores show weak correlation with standard performance metrics.
Researchers used computational lesions on multilingual large language models to identify how the brain processes language across different languages. By selectively disabling parameters, they found that a shared computational core handles 60% of multilingual processing, while language-specific components fine-tune predictions for individual languages, providing new insights into how multilingual AI aligns with human neurobiology.
