Evidence for compositionality in fMRI visual representations
Matteo Ferrante, Tommaso Boccato, Nicola Toschi, Rufin VanRullen · COSYNE 2025
: In neuroscience, the question of how the brain combines individual visual concepts into more complex representations remains unresolved [1,2]. While previous studies have shown that artificial intelligence (AI) systems can encode and manipulate concepts through vector arithmetic (e.g., in language models), it is unclear whether the human brain operates in a similar, compositional manner for visual perception [2]. We tackle the question of whether brain activity patterns can be algebraically manipulated to represent compositional visual information, and if so, whether can we decode these pat
