Behavioral, language, and reasoning are expressions of neural functions par excellence, as the brain must draw on sensory modalities to gather information on the rest of the body and on the outer world. Cortical areas processing the identity and location of the sensory inputs were once thought to be organized, with some branches dedicated to complex features. Yet current studies have uncovered synergistic effects at early-stage cognitions as well as higher-level association areas. A less hierarchical functional architecture of the brain has emerged such that, irrespective of sensory modality, inputs are assigned to the best suited cortical substrate.
