The pressing need to better understand human brain organization is appreciated by all who
have labored to explain the uniqueness of human behavior in health and disease. Early …

Spatial selective attention is widely considered to be right hemisphere dominant. Previous
functional magnetic resonance imaging studies, however, have reported bilateral blood …

Functional MRI (fMRI) is currently used for pre-surgical planning, but is often limited to
