Alzheimer’s disease is the most common type of dementia. Researchers have long believed that this disease will completely wipe out the memory of patients. However, a new study recently found that the memory lost by patients with dementia may actually be recovered Come, because this laser pointer disease may not destroy all memories as previously believed.
This research was carried out by a research team at Columbia University in the United States. The research team conducted this study on rats and found that memory is not completely erased by the disease of Alzheimer’s disease, but it only makes memory more difficult to extract. The new data also shows that these “lost” memories may be reawakened by artificially activating neurons in the storage area.
Alzheimer’s disease is a developing degenerative brain disease that usually occurs in middle-aged and elderly people and is believed to damage memory and other basic cognitive functions. One of the most notable features of this disease is the clumped protein called “beta-amyloid”, a substance that is thought to damage and destroy patients’ brain cells. The researchers found that by stimulating areas of the mouse brain that are related to memory storage, they can wake up the previously lost memory in the mouse.
The team studied two groups of mice, one group was healthy and the other group had diseases equivalent to human Alzheimer’s disease. The researchers genetically engineered these mice so that their neurons glow yellow when memory storage is activated by a green laser pointer, and glow red when memory wake is activated. The researchers then tested the memory of these mice twice. For the first time, the researchers let the rats smell the lemon and then shocked them. After a week, let them smell the lemon again, which will cause a pause in the healthy mice, but the sick mice will not respond.
