The Question of Intelligence




Yes, that's right! Neuron is the word!!

A neuron (or nerve cell) is a type of cell which is the basic building block of the nervous system. Neurons send and receive electrochemical messages to and from other neurons. The 50 billion or so nerve cells of the brain work together to coordinate everything from our heart beating to complex behaviors such as talking with a friend or feeling compassion.
