The long-term potentiation (LTP) and long-term depression (LTD) of the strength of hippocampal excitatory synapse involved in learning and memory formation in brain have been separately explained, but the molecular mechanism that comprehensively explains them has not been elucidated. Associate Professor Dr. Tomonari Sumi, Research Institute for Interdisciplinary Science, Okayama University, and Assistant Professor Dr. […]

Sleep boosts immune systems by making blood cells more able to attack
Sleep off your sickness: Slumber boosts our immune systems by making white blood cells more able to attack Researchers analysed blood taken from participants when asleep and awake Body showed higher levels of a specific T-cell function while asleep A certain group of molecules, such as hormone adrenaline, are lower at night It suggests these […]
Researchers hope to be able to replace dysfunctional brain cells
A new study by researchers at Karolinska Institutet supports the theory that replacement of dysfunctional immune cells in the brain has therapeutic potential for neurodegenerative diseases like ALS and Alzheimer’s disease. The study, which involved repopulating the brain with new immune cells in an experimental disease model, is published in Nature Communications. Macrophages are immune […]
Artificial neural networks now able to help reveal a brain’s structure
The function of the brain is based on the connections between nerve cells. In order to map these connections and to create the connectome, the “wiring diagram” of a brain, neurobiologists capture images of the brain with the help of three-dimensional electron microscopy. Up until now, however, the mapping of larger areas has been hampered […]
