• Evaluation of Localisation of Function

• SUPPORT

• CHALLENGE

• ANIMAL RESEARCH

• CASE STUDY

• Phineas Cage- Metal Rod through head

• Went through prefrontal cortex an area responsible for personality. 

• Accounts say his personality changed after the accident supporting LOF.

• HOWEVER, very individual case study so can't be generalised 

• Study suffers from temporal validity issues because the research is based on sketchy accounts

• Research into the effects of removal of brain matter would have on a rats ability to remember a maze pattern

• Learning is too complicated and requires the involvement of the whole brain

• HOWEVER, rats brains are biologically different from humans (less grey matter) therefore, research can't be generalised.

• PLASTICITY RESEARCH

• Case studies of children born with only one hemisphere have shown that it is possible to function normal lives with only one half of the brain.

• This limits the theory that localisation can only occur in certain parts of the brain.
