Scientists have managed to grow a brain that shows electrical activity

Ученым удалось вырастить мозг, который проявляет электрическую активностьBrain organelles began to show electrical activity.

It is noted that the organelles were three-dimensional, miniature, simplified versions of the bodies. These organelles were grown from pluripotent stem cells. They induced these “forms” for the development of cells that comprise the cerebral cortex – the part responsible for very important things like memory, perception, cognition, thoughts, and sensory processing.

About hundreds of little brains, grown for 10 months. At this time, researchers tested the organelles in order to ensure that they develop the necessary genes. In addition, scientists watched the brain using electroencephalogram (EEG).

About six months brains began to show vigorous brain activity. She was not as organized and predictable as the activity of an adult, but chaotic, synchronized bursts phenomenon reminded of brain activity observed in preterm infants.

Despite the fact that it was not identical, the machine learning model, trained on the signatures of the EEG of premature infants who were able to identify many of the same properties as the normal schedule of development. It seems that for the last 28 weeks, the trajectory of the organelles was consistent with the development of a premature baby of the same age.
