Recently a group of scientists in Israel have developed a way to fashion a computer circuit from the actual neurons that our brain uses to communicate within itself and with the rest of our bodies. They have used cultured neurons in order to create a reliable AND logic gate.
Apparently, the neurons in the brain are characteristically unreliable, only connecting with an adjacent neuron 40% of the time, and although this experiment did nothing to increase the reliability of the connection, it used the same techniques of bundling that the brain uses to get more than 40% efficiency from the neurons themselves. I don’t think that this, as of right now has any groundbreaking implications for human life, but it is still an interesting way to investigate the working so the amazingly sophisticated human brain.
