Topic: cerebro-cerebellar loops

Neural circuits process temporal intervals during adaptive behaviour. However, it is unclear how temporal information enables the brain to create causal maps and predict future events. While the cerebellum is well-known to support sub-second intervals for motor control, the ability to track environmental changes in the range of seconds to minutes is thought to be supported mostly by cerebral areas. We hypothesized that the cerebellum also contributes to behavioural control on a supra-second timescale by interacting with the neocortex through cerebro-cerebellar loops. Using a supra-second time

A recent surge of experimental evidence points towards a significant role of the cerebellum in the development and maintenance of neocortical states through cortico-cerebellar loops. Notably, the re- sulting positive feedback loop is not limited to the motor domain to which the cerebellum is classically associated but has been shown to extend to various cognitive processes. However, it remains unclear what functional principles may underlie these cerebro-cerebellar loops. Here we model a neocortical area as a recurrent neural network which projects to, and receives from, a cerebellar feedforwa
