At the Volga University of Fundamental Medicine, scientists have learned to grow an artificial brain in a test tube from animal biomaterial.
Scientists placed 2,000 neurons in a special environment on a microchip with an area of 1 sq. mm on a grid. It consists of 100 or more microelectrodes under voltage. They register the potential of the cell without violating its integrity.
Artificial neurons exchange electrical impulses and respond to them.
We record them every three seconds. One neural network sends a signal, and the second one reacts to it like a natural neurochemical one, which is in the brain.
The “brain on a chip” grows quickly, neurons connect to each other within five to seven days. So far, the artificial organ can only reproduce elementary functions.
Scientists expect that their development will allow them to grow neurons from human stem cells, create and test new drugs.
Earlier, www1.ru reported that Rosatom will master bioprinting technology by 2030.
