Fig. 6: Circuits for the two cerebellar language functions proposed by the cANN.
From: Emergence of syntax and word prediction in an artificial neural circuit of the cerebellum
The entire circuit is trained to generate the output of next-word prediction (red). In parallel, to enhance the prediction accuracy, a syntactic processing circuit emerges upstream of the predictive output neurons (blue), so that Purkinje cell dynamics represent S-V-O syntactic information. Within the cerebellar internal model framework (bottom enclosure), next-word prediction corresponds to the future event prediction, aligning with the conventional understanding of the internal model function. Furthermore, syntactic processing corresponds to sequential event processing (structural feature extraction from sequential events), which is indicated by the cANN as another critical function of the internal model.
