Rhythms in the brain help give a sense of location, study shows.
Research at the University of Edinburgh tracked electrical signals in the part of the brain linked to spatial perception. Scientists found that brain cells, which code location through increases in electrical activity, do not do so by talking directly to each other. Instead, they can only send each other signals through cells that are known to reduce electrical activity.
This is unexpected as cells that reduce electrical signalling are often thought to simply suppress brain activity.
