Theory of oscillations may explain biological mysteries

...vade. Vandermeer holds out hopes that the study of oscillations in biological populations will lead to insights into complex systems, such as those that include animals that eat other predators as well as omnivores that eat both predators and those predators?prey. ...

Slow brain waves play key role in coordinating complex activity

...llations, or theta waves, "tune in" the fast brain oscillations called high-gamma waves that signal the transmissi...h as listening to a list of words, the slow, theta oscillations in the hearing area of the brain become coupled with the fast, high-gamma oscillations in the same a...

Protein shown to rally biological clock

...d GABA, synchrony was perfectly fine. Instead, the oscillations got bigger.? Herzog likens VIP to the Pony Express rider telling all the SCN cells to synchronize their ; GABA, he says, is like the marshal that prevents he cells from being too active. Herzog and Aton recorded neuron activity from the SCN usin...

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 ...

Nanobacteria in clouds could spread disease, scientists claim

...the relatively dry inter-cloud regions, leading to oscillations 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...

After a time-shift, mixed signals from the circadian clock

...nted by a dorsal (upper) group of cells, exhibited oscillations in activity that corresponded to slow resetting of the clock in response to the shifted light schedule, while another part of the clock, represented by a ventral (lower) group of cells, exhibited a distinct pattern of activity that corresponded to fa...

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...
