How does the brain learn? What exactly happens in the complex network of nerve cells when you master a new skill? Martijn Schonewille looked for the answer in the cerebellum, which is known for its highly organised structure. But how this well-organised machine actually works proved anything but simple.<\/p>\n

The wonder<\/h2>

\u201cWhat happens in your brain when you learn? I have always wanted to know the answer to this question. It\u2019s clear that the cerebellum plays a crucial role. You could describe it as a kind of calculator that fine-tunes movements. I\u2019m intrigued by how well-organised this part of the brain is. Unlike the cerebrum, which is a chaotic mess, patterns seem almost to be recorded in the cerebellum.<\/p>\n\t

Martijn Schonewille is a professor of Neuroscience at Erasmus MC. He studies how the cerebellum contributes to motor skills, cognition and learning. He and his research group study how nerve cells in this brain region process information, among both healthy and ill people. Last month, the Dutch Research Council (NWO) awarded him a Vici grant to establish a line of research and strengthen his research group over the next five years.<\/p>\n\n\t<\/div>\n

\u201cI actually already had a kind of reverse eureka moment while doing my doctoral research. I was studying the learning process in the cerebellum of mice. According to the prevailing theory, a weakening of connections between nerve cells, or long-term depression, was essential for learning. I tested this on mice in which this mechanism had been disabled. The results? The mice were still capable of learning.<\/p>\n

\u201cMy findings caused a stir in the field. Some researchers struggled with the fact that a theory that had been accepted for 50 years was suddenly up for debate.<\/p>\n\n\t

\u201cDuring my research, I noticed something: nerve cells at the front of the cerebellum fire much more frequently than those at the back. Initially, this didn\u2019t seem particularly special, until I compared it with a long-established anatomical fact. The cerebellum is divided into stripes in which cells express either the zebrin protein or PLC-beta 4. This pattern had always been used as a kind of anatomical map: useful for pointing out where you were, but not of any real interest otherwise. However, I was still curious. What if those stripes actually tell us more? Not just the location of cells but also how they behave? Perhaps the researchers who rejected my findings were looking at completely different cell types without realising it.\u201d<\/p>\n\n\t
