This Cranial Stimulator from Fisher Wallace is an at-home treatment that can be used on those who suffer from anxiety, depression, stress and insomnia. It looks like electro-shock therapy and it sort of is.
To use the Cranial Stimulator, you put the moist applicators underneath the headband and then switch it on. A very nominal radio wave is emitted to help stimulate serotonin and dopamine in the brain. The intensity level varies depending on where you turn the power wheel.
It is recommended (by Fisher Wallace) that you use the Cranial Stimulator 20 minutes a day for 30-40 days to benefit fully from this drug-free treatment.
