Human referential communication is often thought as coding– decoding a set of symbols, neglecting that establishing shared meanings requires a computational mechanism powerful enough to mutually negotiate them. Sharing the meaning of a novel sym- bol might rely on similar conceptual inferences across communica- tors or on statistical similarities in their sensorimotor behaviors. Using magnetoencephalography, […]

Two parietofrontal networks share the control of goal-directed movements: a dorsomedial circuit that includes the superior parieto- occipital sulcus (sPOS) and a dorsolateral circuit comprising the anterior intraparietal sulcus (aIPS). These circuits are thought to independently control either reach and grip components (a functional dissociation), or planning and execution phases of grasping movements (a temporal […]

moreOur sensorimotor interactions with objects are guided by their current spatial and perceptual features, as well as by learned object knowledge. A fresh red tomato is grasped differently than a soft overripe tomato, even when those objects possess the same spatial metrics of size and shape. Objects’ spatial and perceptual features need to be integrated […]

Fortunately, we don’t have to think about this when we are standing in the supermarket after a busy day. We carefully grasp that ripe tomato without effort. Such a fluent integration of abstract knowledge (“that tomato is ripe”) and spatial information (“it is there”) is actually extraordinary. While modern computers beat grandmasters in chess, not […]
