Methadone works if used properly

Sensitive thyrotrophin assays: excellent when properly used.

Visual half-field experiments are a good measure of cerebral language dominance if used properly: evidence from fMRI.

Traditional neuropsychology employs visual half-field (VHF) experiments to assess cerebral language dominance. This approach is based on the assumption that left cerebral dominance for language leads to faster and more accurate recognition of words in the right visual half-field (RVF) than in the left visual half-field (LVF) during tachistoscopic presentation. Information in the RVF is directly...

Researchers may not wish to use lengthy scales because their core questionnaires are already long, the patient gro...
