A visual defect simulation system receives a functional field map produced by an MRI system that relates locations in a patient's brain to locations in the patient's field of view. Planned medical operations are indicated at locations in the patient's brain and any resulting vision loss is simulated with a revised functional field map. A scene is displayed and an impairment overlay is produced from the revised functional field map that blocks the scene at locations corresponding to simulated vision loss. The overlay is translated over the scene in response to viewer eye movements detected by a vision-tracking system to present a real-time simulation of the resulting vision loss.

System and method for sensory defect simulation

Neurovascular uncoupling that causes fMRI data to underestimate viable neuronal activity in the brain is detected and indicated to assist in pre-surgical planning. Tasks associated with the cortical region in question are performed while the fMRI measurement of brain activity is measured and the same tasks are performed while task performance is measured directly. Neurovascular uncoupling is detected and indicated by comparing the results of fMRI measurement and direct measurement.

Method for measuring neurovascular uncoupling in fMRI

A video system for use by a patient positioned in the bore of an MRI scanner includes a scope through which the patient can view a remote target area while a scan is being performed. A liquid crystal display system produces a color image at the target area which can be manipulated with a computer to perform MRI brain function experiments or tests.
