Scientists are studying the effect of various brain stimulation techniques in healthy people.
In a recent study reported in the Neural Regeneration Research (Vol. 9, No. 5, 2014), repeated-pulse transcranial magnetic stimulation was administered to healthy people at the left Guangming (GB37) and a mock point, and calculated the sample entropy of electroencephalogram signals using nonlinear dynamics.
Computed Tomography
Computed Tomography (CT) scan is a type of medical examination that uses X-rays and computer processing to create sectional images of the body to provide more efficient results than X-rays.

Additionally, researchers compared electroencephalogram sample entropy of signals in response to visual stimulation before, during, and after repeated-pulse transcranial magnetic stimulation at the Guangming. Results showed that repeated-pulse transcranial magnetic stimulation at the Guangming evokes different patterns of electroencephalogram signals than repeated-pulse transcranial magnetic stimulation at other nearby points on the body surface, and that repeated-pulse transcranial magnetic stimulation at the Guangming is associated with changes in the complexity of visually evoked electroencephalogram signals in parietal regions, central gyrus, and temporal regions.
