What Makes The Brain Tick, Tick, Tick: Researchers Gaining New Insights Into Brain's Internal Clock
...brain contributes its own resonance, and all these oscillations
are monitored and integrated by the basal ganglia or striatal circuits. It's like a conductor who listens to the orchestra, which is composed of individual musicians. Then, with the beat of his baton, the conductor synchronizes the orchestra so that ...

between a dormant state and one of activation," explained Professor Wickramasinghe. "Remnants of a sticky protein (slime) coating nanobacteria makes them act as extremely efficient cloud condensation nuclei, with a tendency to aggregate to clusters u...

Wisconsin researchers identify sleep gene
... In mammals the changes produce hallmark waves, or oscillations
of groups of neurons, easily detected by EEG. The waves are slower during deep sleep and faster during waking times. One way of getting from the faster to the slower state is by opening ion channels, allowing potassium to flow through them. "Our hyp...
