Neuromodulation

What is Neuromodulation?

​

Neuromodulation refers to a range of different techniques for directly influencing the nervous system through electrical, magnetic or infrared light stimuli to alter its activity. These methods are distinguished between invasive and non-invasive techniques.

Non-Invasive Neuromodulation

​

• Transcranial Direct Current Stimulation (tDCS): Uses weak electrical currents applied via electrodes on the scalp.

• Transcutaneous Auricular Vagus Nerve Stimulation (taVNS): Stimulation of the vagus nerve through the skin, typically at the ear.

• Transcranial Magnetic Stimulation (TMS)

• Transcutaneous Electrical Nerve Stimulation (TENS): Known for pain relief.

 

How does tDCS work?

​

Transcranial direct current stimulation (tDCS) is a gentle neuromodulation technology. It modifies the membrane potentials of nerve cells with a constant superficial direct current so that they can achieve their optimal neuronal potential.

tDCS uses weak direct currents via scalp electrodes to influence brain activity, optimizing cognitive functions such as learning ability, memory, mood, and motivation, as well as complex coordinated motor processes.

This gentle neuromodulation has proven effective in modulating neuronal activities, supporting neuroplasticity, alleviating pain, and promoting natural healing processes in the brain, thus improving learning and mood in neurological and psychiatric conditions.

In Austria, tDCS has a long tradition of research. In the last 5-10 years, there has been an enormous surge in scientific research worldwide.

 

How does taVNS work?

Transauricular Vagus nerve stimulation (taVNS) is another non-invasive method where the Vagus nerve is stimulated through electrical stimulation over a specific area on the ear.

This technique leads to an increase in parasympathetic activity with a positive influence on heart rate, digestion, tissue regeneration, and mood regulation.

This technique is being explored for treating conditions such as depression, anxiety disorders, and migraines.

It is also used to improve overall well-being and reduce stress. With minimal pain and very low risk, it can also deliver impressive results, although its exact effectiveness and mechanisms are subjects of ongoing research.
