Visual processing in the brain has been understood as the ventral and dorsal pathways processing "what" and "where" information, respectively. Mocz et al. (Mocz V, Vaziri-Pashkam M, Chun M, Xu Y. J Cogn Neurosci 34: 2406-2435, 2022), however, report that the two pathways code object features in a parallel manner. These results support that information processing in the dorsal pathway is not strictly limited to "where" and that the two pathways work in parallel to process task-relevant information ("what we do with it").
