Le asimmetrie funzionali rappresentano un modo per adattarsi alle diverse condizioni ambientali che sono in continuo cambiamento. L’esempio più evidente di asimmetria cerebrale nell’uomo è la dominanza manuale (handedness) nei diversi compiti motori e manipolatori quotidiani. Seppur la maggioranza degli esseri umani è destrimane, è presente una forte variabilità individuale e non è ancora...
Emerging evidence suggests that decision-making extends into motor response execution. In this study, we assessed the hypothesis that motor decisional components are related to decision confidence. In a visual lexical decision task, participants categorized strings of letters as words or nonwords, and electromyographic (EMG) traces were used to partition reaction times (RTs) into premotor time...
Considerata la loro prossimità filogenetica con l’uomo, i primati non umani hanno suscitato un interesse particolare nella ricerca comparativa volta a individuare possibili precursori della specializzazione emisferica umana. Inoltre, la presenza di una mano prensile caratterizzata da sofisticate abilità manipolative ha reso queste specie un modello fondamentale per approfondire le origini e la...
Introduction
Predictive brain theories suggest that the brain builds internal models to anticipate sensory inputs. Recent findings show that such models influence early sensory representations, shaping perceptual outcomes. Here, we hypothesized that this integration process extends along the cortical hierarchy, reaching the motor system. Specifically, we propose that cortico-spinal...
In everyday life, we all experience that some people move in a similar way to each other, while others appear more dissimilar in their gestures. However, a comprehensive approach to quantify and manipulate the degree of “motor similarity” between individuals has still to be consolidated.
To fill this gap, the ACT2 project built a wide upper-limb kinematics database of 90 healthy right-handed...
Exploring a visual scene is a fundamental human behavior that supports understanding and navigation. During this process, unexpected events may appear in the visual periphery, requiring rapid, coordinated responses. To support this, the visual and oculomotor systems operate in a continuous loop of perception and action —yet before attention and gaze can shift toward new stimuli, this loop is...
