The PMT examines visuospatial skill, general intelligence, visually guided motor planning, and the ability to obey rules. Eight right-handed volunteers were examined with PET using the tracer(More)
Seventeen Type 1 (insulin-dependent) diabetic patients with a history of recurrent and severe hypoglycaemia and Type 1 diabetic patients with no severe hypoglycaemia were compared as regarded performances in tests of neuropsychological functioning.
