tPNS

What is tPNS?

Transcranial Pink Noise Stiulation (tPNS) is a new variation on tRNS.

Pink noise or pink noise or 1 / f noise is a noise in which the spectrum contains lower frequencies than higher frequencies.

This noise form approximates the natural fire pattern of neurons. In order to influence the functioning of groups of brain cells, it is better to approach the language in which neurons communicate as closely as possible.

The closer the natural effect is approached, the more effective the stimulation will be.

A recently published study by our colleagues in New Zealand shows that administering this pink noise stimulation in the anterior cingulate cortex reduces the urge to eat in people with food addiction.

These initial results are promising and may possibly be applied to other conditions.

How is tPNS applied?

Although tPNS is not painful, you may feel slight tingling on the skin under the electrode during stimulation. TPNS has no serious side effects. During a tPNS session, the patient is sitting in a comfortable chair.

As with all other forms of tES, electrodes are placed on the scalp to stimulate a specific part of the brain. Since the scalp and the skull form a barrier with much resistance, only part of the applied electrical flow will reach the cerebral cortex. Yet the strength of the current that reaches the brain cells is sufficient to influence the functioning of the neurons.

To achieve an effect, 2 to 3 stimulations per week are performed. Only after 4 to 5 sessions can it be evaluated whether the stimulation will influence the symptoms. A complete treatment consists of at least 8 to 10 stimulations. In chronic conditions, it is sometimes necessary to repeat these stimuli at regular intervals.
