Signaling mode

In the signaling mode of their elementary units, the computer and the brain have similarities and differences. The transistor in a computer employs digital signaling, which uses zeros and ones to represent information. The brain uses digital as well as analog signaling.

Another important property of the brain is that the connection strengths between neurons can be changed in response to activity and experience. Repetitive training enables the neuronal circuits to become better configured and results in improved speed and precision.
