El lenguaje está parcialmente lateralizado en el cerebro.
Language lateralization in the brain is not fixed; it can vary based on individual experiences and tasks. For example, simultaneous translators tend to lateralize their two languages differently to avoid competition and develop ear preferences. Plasticity in the brain allows young adults to adapt and fractionate different aspects of language into the two hemispheres for greater efficiency. The right hemisphere is particularly responsible for understanding emotional and attentional features of language, as well as prosodic features such as changes in tonality and speed. Damage to the right hemisphere can result in the inability to see the big picture in stories and communication, leading to flat speech. In contrast, damage to the left hemisphere can result in loss of detail but retention of the gist of communication. Furthermore, split brain experiments have shown that the brain can compensate for the separation of functions over time.
