摘要：
Here the authors show that ventromedial prefrontal cortex (vmPFC) levels of GABA and glutamate in human volunteers are predictive of both behavioral performance and the dynamics of a neural value comparison signal in a manner as predicted by models of decision-making, thus providing evidence for neural competition in vmPFC supporting value-guided choice.
