Researchers have identified, for the first time, a precise causal link between neuronal activity in the lateral hypothalamus and the state of REM sleep. Using optogenetics, they were able to induce ...

Automatic sleep stage classification using neural networks represents a significant advancement in sleep research, providing a robust alternative to traditional manual scoring methods. By leveraging ...

Using a neural network model, neuroscientists have found that, as the brain moves between REM and slow-wave sleep cycles, the hippocampus teaches the neocortex what it learned. This process seems to ...

In the cerebral cortex, numerous neurons exchange information through junctions known as synapses. The strength of each synaptic connection changes depending on the activity levels of the neurons ...

MRI image of the brain with the lateral ventricles colored in blue. The ventricles are filled with cerebrospinal fluid. Researchers led by Masako Tamaki at the RIKEN Center for Brain Science in Japan ...

Researchers led by Masako Tamaki at the RIKEN Center for Brain Science in Japan report a link between deep sleep and cerebrospinal fluid, the clear liquid that surrounds and supports the brain and ...
