"I was astonished to see that it worked so specifically," Voss said.
When TMS was used to stimulate this spot, regions in the brain involved with the hippocampus became more synchronized with each other, as indicated by data taken while subjects were inside an MRI machine, which records the blood flow in the brain as an indirect measure of neuronal activity.
The more those regions worked together due to the stimulation, the better people were able to learn new information.
