Study tells about the part of brain that stores memories of the similar places

Study tells about the part of brain that stores memories of the similar places. A new study from Dartmouth College revealed that the three brain regions in the posterior cerebral cortex, which researchers call ‘spatial memory areas’, create connections between the brain’s cognitive systems and memories, which help the brain store memory in normal spaces.

The findings were published in Nature Communications.

lead author Adam Steel, Neukom Fellow and the Department of Psychiatry and Psychiatry at Robertson Lab in Dartmouth explains saying that as they move around our environment, information enters the cerebral cortex and somehow ends up as information about where they are – the question is where this change in spatial information takes place. They also think places with memory can occur where this happens.

Adam said that If you look at the location of the brain areas that process viewing scenes and those that process spatial memory, these spatial areas form a bridge between the two systems. Each area of   the brain involved in visual processing is connected to the memory partner.

In the study, a new method was used. Participants were asked to identify and remember locations in the real world during magnetic resonance imaging (fMRI), which produces high-resolution maps, focusing on brain activity topics.

Past studies on scene observation and memory often use incentives that participants are familiar with but have never visited, such as popular historical landmarks, and incorporate data into multiple studies. By mapping out the brain activity of each participant using the real-world locations they had been to, the researchers were able to dissect the organization with a good brain.

In one study, 14 different participants provided a list of people they knew personally and places they had visited in real life (e.g. their father or their childhood home).

Afterwards, while taking the fMRI scanner, participants thought they saw those people or visited those sites. Comparing brain activity between people and places revealed areas of local memory. Importantly, when the researchers compared the newly identified regions with the brain areas that work on visual scenes, the new regions were sparse but different.

“We are amazed,” said Simbi, “because it is a common understanding that the areas of the brain that perceive it must be the same areas that are made during memory retrieval.”

In another experiment, the team investigated whether the memorial sites were involved in the adoption of common sites. During the fMRI scan, participants were provided with visual images of real and unusual real world locations downloaded from Google Street View.

When researchers looked at neural activity, they found that local memory areas were more active where images of common areas were shown. Spot sites did not show similar improvements when viewing general locations. This suggests that local memory locations play an important role in identifying common areas.

“Our findings help to explain what a typical portrait of a clock tower becomes as we know it, such as the Baker-Berry Library tower here at Dartmouth,” Stel said.
