Centromeres, the DNA sections often found at the center of the chromosomes, display enormous interspecies diversity, despite having the same vital role during cell division across almost the entire tree of life. An international team of researchers has discovered that the variation in centromere DNA regions can be strikingly large even within a single species. The findings, now published in the journal Nature, shed light on the molecular…

Brain-computer interfaces are able to restore some mobility to paralyzed people by controlling exoskeletons. However, more complex control signals cannot yet be read from the head surface because conventional sensors are not sensitive enough. A collaboration of Fraunhofer IAF, Charité – Universitätsmedizin Berlin, University of Stuttgart and other industrial partners has taken up this challenge.

Interferons represent the first line of defence against viral infections and are at the same time an important cause of the age-related loss of function of brain stem cells. Scientists from the German Cancer Research Center (DKFZ) and the University of Heidelberg have now shown in mice that interferon regulates the activity and self-renewal of brain stem cells throughout life.

Researchers at the University of Freiburg Medical School led by Prof. Dr. Johannes Letzkus and the Max Planck Institute for Brain Research have discovered that a little-studied area of the brain, the "zone of uncertainty" or "zona incerta," communicates with the neocortex in unconventional ways to rapidly control memory formation.

Blood-based biomarkers allow the early prediction of Alzheimer's risks

Most dementia diseases develop insidiously and are only detected at an advanced stage. Researchers at the University of Heidelberg and the German Cancer Research Center (DKFZ) have now identified the glial fibre acidic protein (GFAP) in the blood as a promising biomarker that can be used to determine an increased risk of developing Alzheimer's disease up to 17 years before diagnosis.

An interdisciplinary research team at the University of Freiburg has found important clues about the functioning of the sensorimotor cortex. The new findings on neuronal activities in this brain area could be helpful for the further development and use of so-called neuroprostheses. These have an interface with the nervous system and are intended to help compensate for neuronal dysfunctions.

The health of nerve cells is closely linked to the auxiliary cells that surround them, the so-called glial cells. It still remains largely unknown what role glial cells play in age-related diseases.

In the brain of adult mammals neural stem cells ensure that new nerve cells, i.e. neurons, are constantly formed. This process, known as adult neurogenesis, helps mice maintain their sense of smell. A research team led by Dr Francesca Ciccolini at the Interdisciplinary Center for Neurosciences (IZN) of Heidelberg University recently discovered a second stem cell population in the mouse brain.

A centre for model-based artificial intelligence has been set up at Heidelberg University to link mathematical modelling methods with information processing in neuronal networks. The Carl Zeiss Foundation (CZS) is funding the CZS Heidelberg Center for Model-Based AI with five million euros over a period of six years.

In the field of optogenetics, scientists investigate the activity of neurons in the brain using light. A team led by Prof. Dr. Ilka Diester and Dr. David Eriksson from the Optophysiology Laboratory at the University of Freiburg has developed a new method to simultaneously conduct laminar recordings, multifiber stimulations, 3D optogenetic stimulation, connectivity inference, and behavioral quantification on brains.

Rolandic epilepsy is a common form of epilepsy in children which occurs primarily during sleep. Short sounds played during sleep can partially suppress the neuronal discharges characteristic of epilepsy. That’s according to a research team from the University of Tübingen and Tübingen University Hospitals. The team is headed by Dr. Hong-Viet Ngo and Professor Jan Born from the Institute of Medical Psychology and Behavioral Neurobiology.

The mechanisms by which the body measures temperature and regulates its own body heat are vital, but still poorly understood. The discovery of the first heat sensor on nerve cells in the skin, for which the U.S. molecular biologist David Julius received this year's Nobel Prize for Medicine, was therefore pioneering.

International research collaboration explores the properties of different neuron types in the brain motor cortex of mice, monkeys and humans using novel experimental and data analysis techniques.

A pioneering technique developed by the Prevedel Group at EMBL allows neuroscientists to observe live neurons deep inside the brain – or any other cell hidden within an opaque tissue. The technique is based on two state-of-the-art microscopy methods, three-photon microscopy and adaptive optics. The paper reporting on this advancement was published on 30th September 2021 in Nature Methods.

Using virtual reality in the clinic to rehabilitate patients with cognitive disorders

Outdated and inadequate methods of neurological rehabilitation are still being used for patients with neurological diseases or injuries – and what’s more, the treatment is usually too late. This is because cognitive training is especially important in the critical phases when the brain is particularly plastic. The Heidelberg-based company living brain proves that early treatment is possible using an extremely innovative method – with concentrated…

Which neurons in the brain mediate fear responses - and how do they flip the switch when the danger is over? The research team of Prof. Ingrid Ehrlich at the Institute of Biomaterials and Biomolecular Systems (IBBS), Department of Neurobiology studies these questions. Their latest results obtained in collaboration with scientists at the Friedrich Miescher Institute in Basel (Switzerland), the National Institute of Health (USA), and Innsbruck…

Induced pluripotent stem cells (iPSC) are suitable for discovering the genes that underly complex and also rare genetic diseases. Scientists from the German Cancer Research Center (DKFZ) and the European Molecular Biology Laboratory (EMBL), together with international partners, have studied genotype-phenotype relationships in iPSCs using data from approximately one thousand donors.

Certain anchor proteins inhibit a key metabolic driver that plays an important role in cancer and developmental brain disorders. Scientists from the German Cancer Research Center (DKFZ) and the University of Innsbruck, together with a Europe-wide research network, discovered this molecular mechanism, which could open up new opportunities for personalized therapies for cancer and neuronal diseases. They published their results in the journal Cell.

Heidelberg neurobiologists decode central mechanism of degenerative processes in the brains of mouse models and develop new principle for therapeutic agents.
