We studied the aging impact in the rat models of distinct cholinergic neuropathology.
We demonstrated age-related and topographically specific EEGs and cortical drives.
Attenuated REM delta amplitude was the hallmark of aging onset in the NB lesion.
Augmented REM sigma amplitude was the hallmark of aging in the PPT lesion.
Disorders of REM sleep and cortical drives are the hallmarks of pathological aging onset.
