Unreliable neurons improve brain functionalities

Bar-Ilan University

The brain is composed of millions of billions of neurons which communicate with each other. Each neuron collects its many inputs and transmits a spike to its connecting neurons. The dynamics of such large and highly interconnected neural networks is the basis of all high order brain functionalities.

In an article published today in the journal Scientific Reports, a group of scientists has experimentally demonstrated that there are frequent periods of silence in which a neuron fails to respond to its inputs. As opposed to elecronic devices, which are fast and reliable, the brain is composed of unreliable neurons
