Here are a few examples of neural data that may suggest that the cerebellum is not associated with the formation of consciousness:
Damage to the cerebellum: Studies of patients with cerebellar damage have shown that damage to the cerebellum does not typically result in severe impairments in consciousness. For example, patients with cerebellar damage may experience ataxia (incoordination) and difficulty with fine motor control, but they are generally able to maintain normal levels of consciousness.
Functional imaging: Functional imaging studies such as fMRI, PET, have revealed that the cerebellum is not typically activated during tasks that are associated with consciousness, such as working memory, decision-making, and attention.
Neural activity: Studies of neural activity in the cerebellum have shown that it does not exhibit the same patterns of activity that are typically associated with consciousness, such as gamma oscillations and coherence in the alpha and beta bands.
lesion studies: Lesion studies in animal models have shown that lesions in the cerebellum do not lead to a loss of consciousness, but rather affect motor coordination and learning.
