Scientists have discovered a previously unknown brain signal

A group of international scientists managed to identify a completely unique type of signals in the human brain,

which was discovered for the first time.Thus, experts have found in the outer cells of the cerebral cortex a mechanism designed to generate “graded” signals that provoke neurons to implement logical functions.

Noted](https://www.sciencealert.com/a-newly-discovered-signal-in-neurons-hints-at-the-power-of-the-human-brain) that during this work the passage of sodium ions through the synapse was recorded. According to scientists who, using fluorescence microscopy, studied the structure of these sections, when activated, individual cortical neurons are able to exchange calcium ions.

It is established that previously unknown signalsare formed as a result of the interaction of charged particles of such chemical elements as sodium, chloride and calcium. It is known that dendrites play a key role in this process. According to the researchers, this function resembles the work of traffic lights, which either transmit or limit signals.
