Complex neural sleep patterns found in fish

Sleep is quite an interesting mysterious brain process to this day, during which our brain goes through many stages and phases, characterized by a change in physiological features and moments. In addition, many scientists suggest that our brain hides even more complex patterns and mechanisms during sleep – in particular, this can be judged by a recent study by experts from Stanford University who focused on the study of sleep patterns of zebrafish. After conducting several experiments and observations of the sleep state of this type of fish, the scientists came to the conclusion that fish have significantly more complex sleep patterns.

Which in some way brings them closer to us, people – because during research observation, experts determined that danios pass through very similar interchangeable phases of brain rhythmics, just like a person. In particular, they placed several genetically modified fish — in such a way that they could capture the visual signals of their neurons when they were activated — with a super-powered microscope — into small vessels with water and with the help of some third-party factors put them into a state of sleep.

Instead of seeing more or less the same type of sleep mechanism in the fish's brain, scientists noticed that, following signals from neurons and muscular movements, danio fish began to reproduce very similar sleep patterns, like in humans, thus going through some stages of changing brain activity. during sleep. Moreover, using a neural microscope, scientists found that the individual phase transitions in fish are very similar in their characteristics to the phases of fast and slow sleep in humans, which cannot but be an interesting discovery.

Despite the fact that the experience of such an experiment is unlikely in the near future to directly affect the possibility of improving the characteristics and processes of human sleep, it still demonstrates that fish have a much more complex and complex set of brain phases and changes in brain activity during sleep than previously assumed. And this may indirectly affect the development of more effective and interesting ways to improve human sleep in future studies, which promises to provide many interesting things to people.
