| Rats naturally sniff every 200 milliseconds, and it appears that this 5-hertz sniff rate exploits a natural pattern of electrical signals in the brain, called the theta rhythm, which has the same 5-hertz frequency and which is known to be triggered during learning activities. The combined findings suggest that the theta rhythm signifies a powerful patterning of group activity imposed upon a fixed connectivity of neighboring neurons," the scientists conclude. |
