Franz Joseph Gall, a 19th century medical student, created Phrenology, which was an attempt to localize function to parts of the brain by feeling the "bumps" on peoples' heads and asking them about their personality. A critical issue with this method is that…

• there are no "bumps" on the head

• the brain had already been shown to not have any localization of function

• "bumps" on the head do not match the gyri of the brain

• None of the above
