The special part of the brain that gives people a sense of direction has been found by experts. People with powerful never signals in their internal compass tended to be perfect navigators.
The study, released in the Current Biology Journal, advised people get lost when their compass cannot keep up.
The experts in London hope the finding will support describe why direction sense can get worse in situations such as Alzheimer’s disease.
Experts have long trusted that such a signal lived within the brain, but until now it had been clean speculation.
Researchers at UCL (University College London) asked 16 volunteers to familiarize themselves with an easy virtual courtyard.
They were then asked to navigate the part, from the memory alone, while their brain were being watched by an MRI machine.
The scans exposed a part of the mind- called as the entorhinal region – fired up quickly during the jobs.
The powerful the signal in the area, the perfect the volunteers were at finding their way around perfectly.
Dr Hugo Spiers, who led the study, said: “Studies on UK cab drivers have presented that the initial thing they perform when they work out a route is calculate which way they need to head in.
“We now understand the entorhinal cortex is liable for such calculations and the standard of the signals from this area seem to determine how perfect someone navigational professionals will be.”
Dr Martin Chadwick, who has also involved in the study, described: “Our results offer confirm to support the idea that your interior compass readjusts as you move via the environment.
For instance, if you turn left, then your entorhinal area should process this to shift your facing direction and aim direction accordingly.
Previous job by UCL experts uncovered the role the entorhinal area plays in supporting people know what direction they are facing.
This fresh job advises the area also support them decide which direction to move in when heading to a fresh location.
Dr John lsaac, from the Welcome Trust, which supported the study, said: “Why some people are perfect navigators than others in intrinsically amazing, but it also support us describe the procedures that go bad in degenerative issues such as dementia- leaving people feeling confused and lost.
