Brain stimulation


Psychiatric disorders are another area of medicine where BCI devices are showing promise. Transcranial magnetic stimulation (TMS) is a non- invasive brain stimulation method used to treat several psychiatric disorders, including Parkinson’s disease and depressive disorders. Using TMS, a pulsed magnetic field is delivered via a coil to the targeted cortical region. An electric field is generated in the brain by electromagnetic induction. This induced electric field can then modulate neuronal activity non-invasively, greatly facilitating clinical application. However, TMS is unable to stimulate deep brain regions due to the rapid attenuation of the generated magnetic field, which distinguishes it from various conventional invasive brain stimulations. In contrast, temporal interference (TI) stimulation – also a non-invasive method – can stimulate deep brain regions. In a TI, several electric fields with high but slightly different frequencies are generated, which, due to the small frequency difference, form a temporal interfering field to which the neurons of the brain react. With an increase in diseases with a neurological component – such as depression and chronic pain – the rising demand of minimally invasive surgery and an aging population more prone to brain diseases, research and development in the field of brain stimulation is increasing significantly. For instance, the global market size was estimated by Allied Market Research to be around $4.4bn in 2018 and is expected to reach $11.3bn by 2026, growing at a CAGR of 12.5%. This is divided into 24% Active Implantable Medical Devices, 35% Spinal Cord Stimulators, 21% Inner and Middle Ear
