Neuroenergetics of the human brain



The human brain consumes around 20% of the energy produced by the body. While neuroscience research has immensely progressed in understanding the micro- and macroscopic architecture of the brain, the reason for its high energy demands is still a mystery. In my research group, we study how energy metabolism drives neural signaling and whether it is altered in neuropsychiatric disorders. At TUM, I have established simultaneous measurements of glucose, oxygen and neurotransmitter metabolism in the human brain combining quantitative PET, calibrated fMRI and edited MRS on an integrated PET/MR-scanner. We also use TMS to non-invasively modulate human brain activity.
