Observation of cognition effects improvement by repetitive transcranial magnetic stimulation

Repetitive transcranial magnetic stimulation (rTMS) can directly stimulate the nerve cell because of the transparent magnetic field, and it has a direct effect on brain function. Under normal conditions, the left and right cerebral hemispheres are in a mutual equilibrium state. However, the damaged hemisphere after stroke has a deficient inhibitory effect on the undamaged hemisphere, which tends to cause relatively high excitability of the undamaged hemisphere and aggravate the inhibitory effect on the damaged hemisphere. This imbalance can be altered by suppressing the excitability of the undamaged hemisphere. The rTMS can stimulate the brain cortex to improve the cognitive function of stroke patients by promoting the balance of cortical interactions. With the development of the rTMS system in cognitive treatment, a higher specification is required for the rTMS devices, such as focusing point, the flexibility of stimulation mode, complex waveform, etc. Multi-channel rTMS could provide more parameters on the treatment. In this paper, we provide an observation of cognition effects improvement by multi-channel rTMS
