The research at the University of Otago in Dunedin led by Prof. dr. Dirk De Ridder in New Zealand includes four shutters.

The first part is the animal research that, in collaboration with the services 'Anatomy / Physiology' and 'Pharmacology' at the University of Otago, focuses on the elucidation of the brain mechanisms involved in ringing in the ears. In addition, research is being carried out into new stimulation forms for brain stimulation with implanted electrodes.

A second component is the research that focuses on unraveling brain mechanisms involved in alcohol addiction, OCD, and stroke in people who implanted electrodes. This is done in collaboration with the services 'Psychiatry' and 'Endocrinology'.

The third pillar is, in collaboration with the services' Neurology ', Psychiatry' and 'Endocrinology' of the University of Otago, the research on non-invasive neuromodulation methods to treat memory disorders, food addiction, obesity and anorexia nervosa, manic-depressive disorders. Also newer forms of neuromodulation such as High Definition Transcranial Pink Noise Stimulation (HD-TPNS), Infraslow Neurofeedback for food addiction and Neurofeedback for memory disorders are scientifically under scrutiny.

A fourth, but not to be missed, section is the formulation of hypotheses about the functioning of the brain and additional new neurostimulation methods. Without a theoretical model, no specific scientific research can be done.

All these studies are done in a randomized and placebo-controlled manner.
