A space heater will help to localize the heat near the model.
Decreases or increases in muscle tone can help the examiner localize the affected area.
Brain imagining studies (MRI and fMRI) include development of an automated method to localize cortical tubers.
A careful neurological evaluation can help to determine the cause of impairment and help a clinician begin to localize the problem.
