Amazing! Scientists create artificial human brain cells from salt and water

The artificial brain cells created by a team from Utrecht University and Sogang University in the Netherlands use the same water and salt elements as those in the human brain.
 

In an unprecedented breakthrough, researchers have created artificial neurological connectors called synapses using a mixture of water and salt, paving the way for the creation of powerful computers that mimic the performance of the human brain. Artificial brain cells created by a team from Utrecht University in the Netherlands and Sogang University in South Korea use water and salt just like the brain.

Human brains use water and dissolved salt particles known as ions as their medium, whereas advanced computer systems use traditional solid materials for the same purpose. With the current accomplishment, it is now obvious that computers that function similarly to the human brain can be constructed.

The outcomes of the research were published in the journal Proceedings of the National Academy of Sciences. 

According to a study presented in the journal Proceedings of the National Academy of Sciences, scientists have developed an Iontronic memristor that stores water and salt. It is only 150 by 200 micrometers wide, the same as three or four human hairs placed side by side.

This device also remembers how much electrical charge has already passed through it. These electrical impulses, like human brains, induce ions to travel along the cone-shaped channel, with differences in electrical charge resulting in variations in ion movement.

Theoretical physicist Tim Kamsma of Utrecht University wrote in a study published in 'Proceedings of the National Academy of Sciences that it is a critical advancement toward computers that are not only capable of mimicking the communication patterns of the human brain but also using the same medium.
