22 | Can we measure brain activity by combining EEG with transcranial ultrasound?

Höller Y | University of Akureyri, Akureyri, Iceland

Stimulation of the brain using transcranial focused ultrasound has gained a moment in research, opening a new horizon of possibilities in research and treatment in various fields of neurology and psychiatry. However, to date the method is still limited to specific application areas such as the treatment of patients with difficult-to-treat forms of focal epilepsy. The use of ultrasound in brain imaging in non-paediatric populations has been limited to interoperative scenarios. In the present talk an update is given on the high-risk high-gain project "AEGEUS“, funded by the European Research Council and aiming at developing a novel electroencephalographic-Ultrasound device for functional brain imaging and neurostimulation.The device is meant to combine the advantage of the electroencephalogram, providing excellent time-resolution, with the envisioned high resolution in space especially in deeper brain region of transcranial ultrasound. To date, the first experiments are set out to capture signals of neuronal origin with a first prototype. In the present talk, potential application areas in the research and treatment of motion sickness are projected alongside with the envisioned outcomes of the ongoing development and clinical testing of the novel device.
