Highlight Detail
A New Scenario for Negative Functional Magnetic Resonance Imaging Signals: Endogenous Neurotransmission.
Dr. Chang, Chen
The Journal of Neuroscience., Mar 11, 2009Functional magnetic resonance imaging (fMRI) has revolutionized investigations of brain functions. Increases in fMRI signals are usually correlated with neuronal activation, but diverse explanations have been proposed for negative fMRI responses, including decreases in neuronal activity
