If you are a vampire, and, accordingly, you have to live in eternal twilight, then you probably are not all right with your memory - say scientists who have discovered a connection between the intensity of light and the work of the brain systems responsible for memory.
Vampires, however, were not considered in the study, but test animals, in particular - rats, showed sad physiological changes when they lived for several weeks in dim lighting conditions.
“Rats have lost, on average, a third of their dendritic spines - these are membrane formations on the surface of the processes, with the help of which neurons form synaptic connections with other neurons. It goes without saying that the cognitive abilities of the brain, in particular memory, depend on the number of these spines, - say the authors of the study, employees of the University of Michigan.
The memory of test rats, which had to live in the dark for weeks for science, did indeed deteriorate somewhat. This was confirmed by the fact that animals began to cope worse with the tasks associated with finding a path in the maze. In general, even if you are not a vampire, but for some reason live in a twilight light, then this study is a reason to think.
