Olin siinä ymmärryksessä, että pikkuaivoilla on rooli vain motoriikassa, mutta se ei olekaan totta. Suurin osa pikkuaivoista osallistuu ilmeisesti jotenkin kognitioon. https://doi.org/10.1371/journal.pbio.3003688 Poimintoja: ”[T]he cerebellum looks like a high-capacity learning engine that can provide a precisely timed predictive signal learned from a very high-dimensional input.” “Even though the most salient symptoms of cerebellar damage or degeneration in adulthood are the disruption of the smooth coordination of movement, the majority of the human cerebellum is likely not concerned with motor control but instead contributes to a wide range of cognitive functions.” “Systematic mapping studies have revealed a detailed map of the functional specialization of the human cerebellum (Fig 2A), with different subregions engaged in functions such as action observation, verbal and spatial working memory, executive functioning, language, social cognition, and even imagination.” “Perinatal lesions to the cerebellum have a profound impact on motor, language, and cognitive development and substantially increase the likelihood of an autism diagnosis.” “The resection of parts of the cerebellum during childhood can cause a complete or partial cessation of speech, a symptom called cerebellar mutism. Importantly, equivalent lesions in adulthood do not cause similar symptoms, or if they do, lead to much milder deficits.”
