Modular output circuits of the fastigial nucleus mediate diverse motor and nonmotor functions of the cerebellar vermis
The study identified five major types of glutamatergic projection neurons in the mouse fastigial nucleus (cerebellar vermis) with distinct gene expression, morphology, and connectivity patterns. These cell types form modular circuits with specific Purkinje cells and inferior olive neurons and project to distinct downstream targets in the brainstem, thalamus, and forebrain, suggesting their involvement in a wide range of motor and nonmotor functions, including posture, locomotion, oromotor control, orienting, arousal, and cognition.
