# Investigating the cognitive and affective functions of the cerebellum
The functions of the cerebellum are traditionally assumed to be limited to the regulation of motor coordination, balance, and motor speech. In recent decades, however, the results of neuroanatomical, neuroimaging and clinical studies have started to challenge this view, suggesting that the cerebellum is also involved in cognition and emotion. The CEREBEMO project aims at better understanding the cerebellum’s functional specialization and integration in human affective processes but also to investigate, more generally, the basal ganglia-cerebellar network during sensorimotor, cognitive and emotional processes underpinning the habit formation. For this project, we collaborate with the Neurology Unit of the Geneva University Hospitals.

Integrated model of emotional prosody processing. An emotional prosodic stimulus is processed by the cortex, the basal ganglia, and the cerebellum. Each sensorimotor (yellow), associative (orange), and limbic (green) region of each structure takes part in this processing. The functional gradient present for the basal ganglia is represented by the overlapping colors. The basal ganglia and the cerebellum are involved in different temporal pattern processing. The basal ganglia process regular temporal patterns in order to detect global similarity with previous responses to what was previously rewarded. The cerebellum processes irregular temporal patterns to detect the fine variations that possibly deviate from what is tolerated in terms of a response in relation to the individual's current state. The chunking process is elaborated by the basal ganglia if emotional sequences are recurrent, as induced by a triggered stimulus (internal or external), and, once started, it may come to an end without conscious control. Chunks are also refined by the cerebellum to gain precision so that the basal ganglia can activate downstream regions more quickly to generate a response.
