Researchers use LLMs and simulation to decode brain activity and infer stimuli

Researchers have developed a method to reverse-engineer brain function models using simulation-based inference. This approach allows for the recovery of stimulus properties from synthetic brain activity generated by models like TRIBEv2. By pairing brain emulators with large language models (LLMs), the study demonstrates a probabilistic mapping from brain maps to latent stimulus parameters, paving the way for decoding and inverse design in neuroscience.
