The representation of object-concept primitives across the macaque brain
Current Biology · By Spencer R. Loggia, Helen E. Feibes, Stuart Duffield, Karthik Kasi & Bevil R. Conway ·
The Brief
- Loggia et al. trained macaques for years on color-shape associations.
- The team used fMRI while the monkeys held in mind features cued by their associates.
- The results suggest a whole-brain layout for object concepts, with retinotopic cortex encoding perception and anterior IT using color.
Why it matters
The study proposes how object concepts may be distributed across the primate brain, linking perceptual areas to higher-level regions. This helps science readers test models of how perception and conceptual knowledge relate.
