Researchers set up 31 male college students to have the ability to transfer round varied digital rooms whereas lying inside an MRI machine that scanned their brains. Outfitted with VR glasses and a joystick, individuals got 30 seconds in every room.
The duty was to recollect the room and the objects. Afterwards, they have been allowed to rest, and at last they were given a distracting process where they used different components of the mind. Mind activity was recorded throughout all phases.
Researcher Hallvard Røe Evensmoen and professor Asta Kristine Håberg at NTNU’s Division of Neuromedicine and Movement Science used practical MRI and self-developed laptop methods within the analysis mission.
The systems provided new information about how the brain perceives and remembers a new place or landscape.
The research report was printed in the renowned scientific journal Cell Reviews.
Stunning discovery #1: We remember the place, however not what
It turned out that the themes had a neater time remembering where issues had been positioned than precisely what things had been positioned in every location.
“In the most excessive circumstances, the topic might bear in mind the place sample of the landmarks precisely, with out remembering which landmarks had been situated the place. Our mind is pretty set on remembering the positions of landmarks,” says Evensmoen.
The analyses of the information from the MRI scan confirmed that remembering positions and remembering objects related to the positions are represented in two totally different but synchronized networks within the brain.
Previous analysis has made no distinction between these two parts of memory
“The coding of the capabilities is totally different, but they’re positioned in the same area of the brain, the medial a part of the temporal lobe, the place the hippocampus and different reminiscence areas are located,” says Håberg.
Stunning discovery 2: Good networks imply every little thing
Their analysis also revealed that more components of the mind than previously thought are concerned in remembering a brand new landscape.
An intensive community of mind areas has to work carefully collectively when we form a cognitive map—an idea in our mind—of a brand new panorama.
“The cognitive map is shaped in a network of mind areas with synchronized activation and overlapping features,” say the researchers.
Areas which are essential for sight and emotions are additionally necessary for remembering a new place.
It has been widespread to assume that spatial reminiscence is organized with the hippocampus as a kind of central hub, however this isn’t completely true in accordance with Evensmoen’s and Håberg’s latest research.
The themes with essentially the most parallel connections within the brain have been the ones who were best at remembering exactly the place within the surroundings objects have been positioned.
“Efficient networks are crucial for a way nicely you remember positions and objects in a new place,” Evensmoen says.

Stunning discovery 3: The brain worked largely during relaxation
The experiment also confirmed that brain exercise increased and that even more connections within the mind were activated during the rest interval after members had finished shifting round each room.
“A secondary finding in our analysis was that the members’ brain activity was better after they were resting than after they moved around the rooms. The mind continued to work on establishing a cognitive map although they not had been shifting round within the setting,” say Evensmoen and Håberg. They are saying this a very interesting discovery and that it fits nicely with earlier data.
“What you expertise during the day continues to consolidate in the brain if you sleep. Taking a nap in the course of the day strengthens reminiscence,” Håberg adds.
Plan to proceed reminiscence studies
“What can be useful now is that we’ve got a brand new starting point for studying memory with the outcomes and strategies we have developed. We’ll have the ability to see if there are variations in different kinds of memory than spatial, like illness or getting old, and whether or not these rules also apply to them,” says Håberg.
Extra exact data could make it simpler to detect early signs of illness versus normal growing old in the elderly, for instance. It may also present a foundation for higher train packages for people who have numerous types of mind injury.
