Question

What sorts of signals does the brain use to communicate sensations, thoughts and actions?

Answer 1

In brain, messages are sent and received by neurons. Neurons send and receive messages between the body to the brain by using electrical and chemical transmitters.

By this I mean that electrical impulses that correspond to a message are passed along the cell, and at the end of the cell, these electrical impulses trigger the release of chemicals, which move and trigger an electrical impulse in the next neuron cell. This passing along of messages is called transmission, and hence the term electrical and chemical transmitters.

Answer 2

" Chemical signals "

Actually brain has connection with whole body by the nerve cells.

These nerve cells or neurons are responsible for carrying on any electrical signal or stimuli to the sense organ for the action against any stimuli.
