the adult human brain is essentially immutable, hardwired, fixed in form and function (this is dogma)

'''Immutability''' is the inability of a thing to be changed. For example, it is impossible to change a dog into a cat. Likewise, it is impossible to change one's [[race]], although with makeup or plastic surgery has made it possible to alter one's racial appearance. The immutability of membership in a group is an important consideration in determining the level of scrutiny given to a law against that group under the [[Equal Protection Clause]].

==Gender and homosexuality==
There is some debate over whether a "[[sex-change]]" operation is valid as regards whether one's sex is immutable or not.

==Neuroscience==
:For decades, the prevailing dogma in neuroscience was that the adult human brain is essentially immutable, hardwired, fixed in form and function, so that by the time we reach adulthood we are pretty much stuck with what we have.
