Research focus:

The mind consumes 20% von the human being body’s power budget. Neuronal communication amongst highly connected brain regions zu sein the main driver of ns brain’s power demands. While us know much about ns macroscopic organization des the human brain in specialized regions and brain networks, ns energy budget of human mind function is still unclear. Moreover, brain metabolism zu sein heavily disturbed in several neuropsychiatric disorders but die relationship kommen sie brain network interaction is also unknown.In my study group, us measure energy consumption von the human brain und relate these to common measures des brain organization. We all at once acquire power metabolism und brain connectivity measures on in integrated PET/MR (Siemens Biograph mMR) scanner. We measure inhibitory and excitatory neurotransmitter levels using 1H-Magnetic Resonance Spectroscopy (MRS) and modulate mind function making use of non-invasive, stereotactic transcranial magnetic stimulation (TMS).
