Transcranial Random Noise Stimulation (TRNs)

Transcranial Random Noise Stimulation (tRNs) is a variation of tACs. But instead of changing the flow direction continuously and rhythmically, the load is varied in a randomized way. This is how an “electric noise” is formed.

What is it?

Is neuromodulation dangerous?

Neurons exchange information when they work in the same phase or rhythm: “Cells that fire together, wire together” (Hebbian Rule, 1949). Our research and that of other groups shows that diseases such as tinnitus, fibromyalgia, chronic fatigue syndrome, chronic pain,... persist because a 'faulty' functional network has formed in the brain. That's why these disorders are so persistent and difficult to treat.

‍

Hypothetically, TRNs can disrupt the rhythm within functional networks. As a result, communication within a pathological network can disappear, which could reduce symptoms.

‍

Studies in people with tinnitus show that when TRNs are administered at the level of the auditory cortex, this can have an effect on the loudness of the tinnitus.

How do we apply it?

Wanneer mag neuromodulatie niet worden toegepast?

TrNS is not painful, although you feel slight tingling on the skin under the electrode during stimulation. tRNS has no serious side effects. During a TRNS session, the patient sits in a comfortable chair.

‍

Like all other forms of tES, electrodes are placed on the scalp to stimulate a specific part of the brain. Only part of the administered current will reach the cerebral cortex, as the scalp and skull form a barrier with a lot of resistance. Nevertheless, 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 5 to 6 sessions can it be evaluated whether the stimulation will influence the symptoms. A complete treatment consists of at least 8 to 12 stimulations. To maintain the effect, the frequency of the stimulations is gradually reduced after an intensive treatment period.

‍
At various points in the treatment process, the clinical effect is discussed during a follow-up consultation.
If necessary, a qEEG control will be carried out.
