Peter Hegemann and his colleagues were awarded the Nobel Prize in Physiology or Medicine for research that enables neurons to be controlled with the help of light

Peter Hegemann, a professor at Humboldt University of Berlin, is one of three laureates recognized for research that has made it possible to control neuron activity using light. Their discoveries have opened up new avenues for studying neural circuits and understanding how the brain functions.

The technology, known as optogenetics, uses light-sensitive proteins to activate or inhibit individual cells with high precision. The method allows researchers to analyze the role of neurons in various biological processes and could contribute to the development of treatments for neurological disorders.

The European Commission highlighted that Hegemann benefited from millions of euros in European funding. Between 2016 and 2021, he received a €2.4 million grant for the MERA project, dedicated to studying light-sensitive proteins.

From 2022 to 2028, the researcher is involved in the SOL project, funded with nearly €8 million through a synergy grant. The team is developing light-controlled molecular switches.

Hegemann also participated in the STARDUST project, carried out between 2017 and 2022, which aimed to develop an ultrasound-powered implant. The technology combines optogenetics, electrophysiology and pharmacology and could be used in research on Parkinson’s disease.
