Dr. Hannes Petersen sérfræðingur í HNE-lækningum og Dr. Björn Gunnarsson sérfræðingur í svæfinga- og gjörgæslulækningum, ásamt samstarfsaðilum fengu nýverið yfir 400 milljóna króna styrk úr Horizon Rannsókna- og nýsköpunaráætlun ESB.
Styrkurinn nýtist til rannsókna á raflífeðlisfræði mannsheilans og þróunar á nýjum tækjabúnaði til myndgreiningar og örvunar á ákveðnum svæðum heilans (A Novel EEG Ultrasound Device for Functional Brain Imaging and Neurostimulation). Rannsóknin er samstarfsverkefni sjö evrópskra háskóla og er Háskólinn á Akureyri einn þeirra. Styrkurinn er til fjögurra ára og í heild sinni getur hann numið allt að 420.000.000 ISK.
Dr. Yvonne Höller, prófessor við Hug- og félagsvísindasvið Háskólans á Akureyri, stjórnar þeim þætti rannsóknarinnar sem fer fram á Akureyri. Yvonne hlaut nýlega Hvatningarverðlaun Vísinda- og tækniráðs 2022, en verðlaunin eru veitt vísindamanni sem þykir hafa skarað fram úr snemma á ferlinum og skapað væntingar um framlag í vísindastarfi sem treystir stoðir mannlífs á Íslandi.

The overall goal of this project is to develop a radically new diagnostic and therapeutic device for neurological applications which combines a highly innovative ultrasound component for brain imaging and focused stimulation of brain regions with advanced electrophysiological measurements of neural activity.
First goal of the project is the development of a novel ultrasound (US)-based functional imaging method that, in conjunction with electroencephalography (EEG), allows for high spatiotemporal resolution examination of brain activity. While EEG itself yields best data from neural tissue close to the skull, the US component is designed to deliver images from deeper brain regions.
The second pillar of the device’s function is focused US brain stimulation. Based on the possibility to localize abnormal activity, the neuromodulation component of the novel device can be guided to focal stimulation of selected brain regions, which can be further developed into a closed-loop design.
The full envisioned system is a versatile tool that combines EEG-sensors and US transceivers in a wearable headset. The project foresees the development of hard- and software as well as algorithms to integrate the information from both modalities into functional neuroimaging with unpreceded spatiotemporal resolution. Beyond the technical realization, this project includes a proof of concept study to evaluate and demonstrate practical applicability in healthy participants and in patients with epilepsy, during clinical routine examination, cognitive, and sensory stimulation, including test-retest validation.
The new device will reduce the time to examine and treat neurological patients and the cost thereof. The ability to perform better diagnosis via accurate imaging, targeted neurostimulation, and neuromodulation with a cost-effective, noninvasive device will have transformative effects on treatment options for neurological diseases and stimulate new lines of research in cognitive neuroscience.
