|EEG in Gamma-A gamma wave is a pattern of neural oscillation in humans with a frequency between 25 and 100 Hz, though 40 Hz is typical.|
A mouse endowed with an astrocyte signalling switch may prove useful in future experiments—and may enable the researchers to continue to explore how gamma waves enable recognition of what’s new and different, a cognitive task equally essential for humans to make their way in the world.

In "we create reality" listed in blog post below, a simple suggestion it seems makes thinking in this range somewhat appealing? I mean, is it really that easy that what we choose to do with our thinking can actually produce physiological implications in the thinking brain so as to suggest we can actually create these states?
Frederick Travis, PhD, director of the Center for Brain, Consciousness and Cognition, explains that the concept "We create our reality" is more than a philosophical statement. It is a physical reality driven by neural plasticity—every experience changes the brain. Therefore, choose transcendental experiences and higher states of consciousness naturally unfold. See: We Create Our Reality (underlined for emphasis by me).
Calcium Waves-Astrocytes are linked by gap junctions, creating an electrically coupled (functional) syncytium. Because of this ability of astrocytes to communicate with their neighbors, changes in the activity of one astrocyte can have repercussions on the activities of others that are quite distant from the original astrocyte.
An influx of Ca2+ ions into astrocytes is the essential change that ultimately generates calcium waves. Because this influx is directly caused by an increase in blood flow to the brain, calcium waves are said to be a kind of hemodynamic response function. An increase in intracellular calcium concentration can propagate outwards through this functional syncytium. Mechanisms of calcium wave propagation include diffusion of calcium ions and IP3 through gap junctions and extracellular ATP signalling. Calcium elevations are the primary known axis of activation in astrocytes, and are necessary and sufficient for some types of astrocytic glutamate release.
