The hub and spoke model of semantic processing. The various different modality-specific surface representations correspond to motion (yellow), colors (dark blue), shape (green), names (orange), actions (light blue) and task (purple), and are directly connected via green lines. These all connect (shown as red lines) to a shared, amodal “hub” (shown as a red area) in the anterior temporal lobes. At the hub stage, therefore, associations between different pairs of attributes (such as shape and name, shape and action, or shape and color) are all processed by a common set of neurons and synapses, regardless of the task.
