We are grieving for Professor Dr. Uwe Heinemann, the highly regarded and warmly regarded former long-standing Head of the Institute of Neurophysiology
Uwe Heinemann studied medicine in Munich. Following doctoral studies and training in Oxford, he returned to Germany, joining the Max-Planck-Institute for Physiology in Munich. In 1986, he was appointed Professor for Physiology and Pathophysiology at the University of Cologne. In 1993 he accepted a call to the Charité Berlin. His tireless commitment over the following 17 years saw the Institute of Neurophysiology develop into a research center of international renown. After retiring as Institute Head in 2010, he was appointed Senior Professor at the Neuroscience Research Center, Charité, in 2012.
Berlin's post-German unification neuroscience community was shaped to a great degree by Uwe Heinemann's tireless efforts in heading the former Institute of Physiology, later called Johannes-Müller-Institute of Physiology and his establishment of numerous large-scale research collaborative centers. He also laid the groundwork for the Charité's Cluster of Excellence NeuroCure, of which he was a founding member and co-director until 2010. His research and generous collaborative approach significantly influenced the today's Institute of Neurophysiology, specifically, and the wider field of neuroscience, more broadly.
His main research interests were mechanisms of and pharmacoresistance to epileptogenesis and, in later years, the mechanisms underlying learning and memory. Numerous international research awards and his participation in a wide range of expert panels, including those of the German Research Foundation and European Research Council, testify to the high regard he was held in by the scientific community both at home and abroad.
- General anaesthesia is required for surgical interventions or during treatment on intensive care units. Our principal aim is to understand possible pathophysiological mechanisms concerning neurological disorders related to anesthesia. We therefore investigate the effects of anesthetics on neuronal oscillations, neurotransmission, ion homeostasis and neuronal metabolism.
- Blood-brain barrier dysfunction – a state of abnormal trafficking from blood to brain and vice versa – is common in patients suffering from stroke, traumatic brain injury, epilepsy, brain tumors or vascular dementia and likely influences their outcome. We induce increased BBB permeability using the neocortical photothrombosis model and investigate the role of network dysfunction, namely seizures and spreading depolarizations on tissue viability and BBB integrity.
- Different oscillatory rhythms of the brain mediate different functions of the brain. Sharp wave ripples (SPW-Rs) in area CA3 and CA1 of the rat hippocampus occur during immobility, consummatory behavior and slow-wave sleep and play a critical role in memory consolidation. In acute rat brain slices, SPW-Rs occur together with dentate waves (DWs) of the dentate gyrus and the hilus. We investigate how neuronal ensembles can create, maintain, and modulate these rhythms.
- Neurometabolic coupling: Energy metabolism and neural activity are tightly coupled processes. Metabolic substrates can alter neuronal activity by modulating different signaling pathways. This makes them alternative therapeutic targets for conditions like seizure disorders. Apart from glucose, the brain can utilize alternative energy substrates such aslactate, ketone bodies, glutamate etc. Lactate, once considered a mere glycolytic byproduct, has been shown to alter neuronal activity through a G protein-coupled receptor (GP81). Hence, we investigate the role of intrinsic lactate for neuronal metabolism, synaptic transmission, ionic homeostasis and pathological network activity in acute rat slices and neocortical slices from patients with temporal lobe epilepsy.
