In Ronald Bailey's The Battle for Your Brain he challenges eight objections to enhancing human performance with neurotechnology.

He debunks the claims that neurological enhancements:

1. Permanently change the brain
   
2. Are anti-egalitarian
   
3. Are self-defeating
   
4. Are difficult to refuse
   
5. Undermine good character
   
6. Undermine personal responsibility
   
7. Enforce dubious norms
   
8. Make us inauthentic

"In the 1960s many states outlawed the birth control pill, on the grounds that it would be too disruptive to society. Yet Americans, eager to take control of their reproductive lives, managed to roll back those laws, and no one believes that the pill could be re-outlawed today." 

Neuroethics is a topic that needs to be watched closely, our cognitive liberty is at stake.
