Gwynne D. Koch

Commonly used functional MRI protocols are not suitable for directly measuring blood oxygen level-dependent responses from very small brain structures that are of interest to neuroscientists, particularly the brain stem nuclei of the dopamine, norepinephrine and serotonin systems. Imbalances in these systems, which play a critical role in the regulation of brain function, have been linked to most major psychiatric disorders, including addiction and schizophrenia, and to Parkinson’s disease. To study the dopamine system with MRI, scientists previously had to examine other more accessible...Read full article
