▪A study by the International Institute of Information Technology, Hyderabad, showed a noticeable degradation in brain alignment when dropping from a 3-billion parameter model to a 1.5-billion parameter model
▪Guiding large language models with task-evoked brain signals increased reasoning accuracy by up to 13 percentage points in the strongest reported cases
▪Brain-guided steering of language models can be applied during inference to modify processing on demand, or during training via fine-tuning to incorporate brain-derived information long-term
