The Cerebellum: Beyond Motor Skills, a Key Player in Social and Cognitive Function
For years, the cerebellum was primarily recognized for its role in coordinating motor skills. However, recent research has unveiled a surprising truth: this brain region plays a crucial role in social and cognitive functions as well.
Professor Frank Van Overwalle from the Brain, Body and Cognition research group at the Vrije Universiteit Brussel (VUB) is leading the charge in understanding the cerebellum’s broader impact.
"People with cerebellar abnormalities often experience motor issues," explains Van Overwalle. "For example, they might struggle to smoothly touch their nose with a finger. These difficulties highlight the cerebellum’s essential role in refining motor movements."
But Van Overwalle’s research goes beyond motor functions. He’s discovered that abnormalities in the cerebellum are linked to emotional and behavioral disorders, particularly in individuals with autism.
Brain Stimulation: A New Hope for Autism
Through non-invasive brain stimulation techniques like magnetic and electrical stimulation, researchers are making strides in improving social task performance in people with autism.
"We’ve seen improvements in the sequence of cognitive tasks in people with autism through magnetic stimulation," says Van Overwalle. "We’re now testing more complex tasks to see if these effects can be further enhanced, with the ultimate goal of developing practical treatments for people with autism."
Transcranial electrical stimulation (tES) is a particularly promising technique. It’s more affordable and accessible compared to magnetic stimulation, offering potential for widespread application in the future.
A New Understanding of the Cerebellum
This research is shifting our understanding of the cerebellum’s function. It’s no longer simply a region associated with motor skills. Instead, it’s emerging as a key player in social and emotional learning, potentially impacting the development of new therapies for a range of neurological and psychiatric conditions.
"Our hope is to refine these techniques further to improve social and cognitive functions in people with autism," concludes Van Overwalle.
