According to an ELISA kit study in Nature-Neuroscience, when exploring a virtual environment, the human brain exhibits grid-like activity. This shows that the navigation system in our body is active even when the body does not move in the sense of physical space.
Previous studies believed that animals ’perception of space stems from the action of two types of nerve cells called space cells and grid cells. When animals enter a specific area of ​​the environment, space cells become active, while grid cells Responsible for displaying this spatial pattern of cellular activity, similar to the grid on the map. Although space cells have been found in the human brain, grid cells have only been found in rodents, bats and monkeys.
Joshua Jacobs and others reported grid-like activity in the human brain, providing the most direct evidence for the presence of grid cells, which also shows that the human navigation collaboration system of the ELISA kit is similar to other mammals.
The researchers implanted the electrodes intracranially into the brains of patients with drug-resistant epilepsy undergoing treatment, and recorded the activity of nerve cells. They let the patient use the joystick to find objects in the computer's virtual environment, and then use the records to find the grid-like structure in the patient's brain.
Jacobs also noticed that the nerve cells in the olfactory cortex and cingulate cortex of the brain became active in the multiple positioning of the environment and formed a lattice covering the entire virtual space. The grid-like activity pattern of the human brain in the ELISA kit is very similar to the characteristic pattern of grid cell activity in the brain when animals are exploring natural spaces.
