Final answer:
Medications targeting the monoaminergic and cholinergic systems, as well as deep brain stimulation, non-invasive brain stimulation, cognitive behavioral therapy, and exercise can modify cognitive function.
Step-by-step explanation:
There are several factors that can modify cognitive function. Medications targeting the monoaminergic systems, such as methylphenidate and modafinil, can enhance cognitive function in healthy individuals. Drugs like donepezil, rivastigmine, or galantamine that target the cholinergic system can also improve cognition. Other methods, such as deep brain stimulation and non-invasive brain stimulation, as well as cognitive behavioral therapy and exercise, can also modify cognitive function.
