Sleep is an interesting and mysterious brain process to this day, during which our brain goes through many stages and phases, characterized by a change in physiological characteristics 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 recently published study by specialists from Stanford University, who focused on studying sleepy zebrafish patterns. After conducting several experiments and observation sessions on the state of sleep of this species of fish, 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 the research observation, experts determined that zebrafish go through very similar interchangeable phases of brain rhythm, like a person. In particular, they placed several genetically modified fish – in such a way that with the help of an ultra-powerful microscope they capture the visual signals of their neurons when they are activated – in small vessels with water and using some external 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 according to the signals of neurons and muscular movements, zebrafish began to reproduce very similar patterns of sleep, as in humans, thus going through some stages of changing brain activity during sleep. Moreover, using a neural microscope, scientists found that 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 to directly affect the possibility of improving the characteristics and processes of human sleep in the near future, it nevertheless demonstrates that fish have a much more complex and complex set of brain phases and changes in brain activity during sleep than assumed earlier. And this may indirectly affect the development of more effective and interesting ways to improve human sleep in future research, which promises to provide a lot of interesting things for people.
