This data in aging mice strongly suggests that topical or oral nicotine or nicotine-like substances may be profoundly beneficial for aging humans with central auditory processing disruptions.
Age-Related Hearing Loss and Brainwave Changes
Brain oscillations (brainwaves) are associated with specific cognitive and sensory processes. How age-related hearing loss (presbycusis) alters the oscillations is unclear. Age-related speech recognition problems can be caused by changes in neurotransmission (chemical messaging between nerve cells) and temporal processing (the perception of sound within a defined time frame).
