Scientists have discovered a hidden structure in the connections between neurons in the brain, which is crucial for the stability of the neuronal network. By combining mathematical models with experimental recordings, researchers found that the relative ratios of connection strengths are more important than absolute values.
Researchers found that vagus nerve stimulation increases coupling between the stomach and brain, particularly in regions already communicating with the stomach. This improvement can be produced almost instantaneously and spread rapidly.
Researchers found that appetite changes in depression are linked to specific changes in the brain's reward system, including a weaker connection between the reward system and areas processing taste stimuli. The study suggests precision medicine approaches could lead to more targeted therapies for individual symptoms of depression.
Scientists at University Hospital Bonn compared PELDOR and FRET spectroscopy methods to measure distances in protein molecules. While most results were comparable, inconsistencies were found in two cases, highlighting the importance of re-measurement with another nano ruler.
