The arcuate fasciculus shows distinct connectivity patterns in macaques and humans, with human-specific expansions and connections likely supporting advanced language processing.
Researchers studied the arcuate fasciculus, a key brain structure involved in language, in both macaques and humans to understand its connectivity patterns. They found that while the arcuate fasciculus in macaques connects the temporal-parietal cortex to prefrontal regions, in humans, it has expanded connections, particularly in areas linked to language processing. These differences may explain why humans have more advanced language abilities. The study also provides insights into how disruptions in these connections could lead to language disorders like aphasia and dyslexia.
