High-Resolution Mapping of Discrete Representational Areas in Rat Somatosensory Cortex Using Blood Volume-Dependent Functional MRI

The present study documents the use of an iron oxide-based blood-pool contrast agent in functional magnetic resonance imaging to monitor activity-related changes in cerebral blood volume (CBV) resulting from peripheral sensory stimulation and the application of this technique to generate high-resolu...
