Neuroimaging Technique Captures Cocaine’s Devastating Effect On Brain Blood Flow
Researchers from the Department of Biomedical Engineering at Stony Brook University have developed a high-resolution, 3D optical Doppler imaging tomography technique that captures the effects of cocaine restricting the blood supply in vessels — including small capillaries — of the brain. The study, reported in Molecular Psychiatry, and with images on the journal’s October 2012 cover, illustrates the first use of the novel neuroimaging technique and provides evidence of cocaine-induced cerebral microischemia, which can cause stroke.
