Localisation of Function Evaluation

There is plenty of evidence to support the idea of localisation that comes from case studies. For example, patient Tan, who could only say the word 'Tan', however his intelligence seemed unaffected, his mental and physical faculties intact and responsive. He had impaired speech but intact comprehension.
