Neuroenergetics of the human brain

We study the energy metabolism of the human brain and how it relates to neural signaling in the healthy and diseased brain at Technische Universität München (TUM) in Munich, Germany.

Valentin Riedl  Principle Investigator

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 on the Neuroenergetics of the human brain, I study how energy metabolism drives neural signaling and whether it is altered in neuropsychiatric disorders. 

At TUM, I have therefore established simultaneous measurements of glucose and oxygen metabolism in the brain combining quantitative PET, calibrated fMRI and edited MRS. I received my MD ( from TUM and my PhD (Systemic Neurosciences) from LMU after working as a Research Fellow at the World Health Organization. I am currently a Junior Fellow and lecturer (Priv.Doz.) at TUM.

Katarzyna is an expert in measuring metabolites in the human brain using MRS. In her PhD thesis she studied the dynamics of inhibitory and excitatory neurotransmitter in the visual system. 

Kasia is experienced in fMRI, edited MRS, and quantitative PET imaging. She has a background in psychology. For her PhD, she won a scholarship of the MLST Graduate School as one of the top 5 applicants. If you look for the best Pierogi place in Germany, Kasia will find it.

Samira Epp PhD-student

Samira studies the energy consumption of human brain networks when subjects perform cognitive tasks. She is an expert in dynamic network interactions and for sophisticated statistics to analyze fMRI data. Samira received a BSc and MSc in Psychology and joined our group in 2018 to implement quantitative BOLD and PET imagig. If you search for Bouldering spots in Bavaria, ask Samira!

Gabriel Castrillon PostDoc

Gabriel is a data whisperer handling graph metric analysis and machine learning. In his PhD thesis, he investigate the effect of non-invasive brain stimulation (using TMS) on functional brain integration. Gabriel has a background in biomedical engineering and computing. He won a scholarship of the MLST Graduate School, was supported by a State scholarship of his home country, Columbia, and received the 2018 OHBM abstract merrit award. If you intend to visit the Columbian jungle, he is your guide.

PostDoc and PhD positions are regularly available.

Our work
<p>Multiscale brain imaging&nbsp;</p>

Multiscale brain imaging 

Inspired by molecular and cellular neuroenergetics, we develop novel strategies to integrate signals from multimodal brain imaging in order to better understand the energy profile of human brain function.
Energy Metabolism
Energy Metabolism
We study the energy metabolism of glucose in the human brain using Positron Emission Tomography (PET). We recently implemented quantitative PET imaging on an integrated PET/MR-scanner to directly measure glocose metabolism.
brain networks&nbsp;
brain networks 
We study the macroscopic organization of neural signaling in the human brain applying graph metrics to Functional Magnetic Resonance Imaging (fMRI) data. We currently implement calibrated fMRI to directly measure oxygen metabolism.


We study inhibitory (GABA) and excitatory (glutamate) neurotransmitter levels in the human brain using Magnetic Resonance Spectroscopy (MRS).
