Normal mice: Neurons in the deep cerebellar nuclei are wrapped by protective perineuronal nets (PNNs) and become strongly activated during social interactions. This activity supports efficient signal transmission through cerebellar neural circuits and their connected brain networks, enabling typical social behavior. ASD-related mouse models and mice with experimentally disrupted PNNs: Loss of PNNs is linked to increased expression of the transcription factor ARNT2 and a marked reduction in neuronal activity within the deep cerebellar nuclei. Diminished cerebellar output leads to weaker activation of downstream brain circuits involved in social processing, ultimately resulting in impaired social behavior.
