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

The brain along with the spinal cord makes up the nervous system which is the body control centre. This is connected to the rest of the body by the cells called neurons. Neurons send and receive messages between the body to the brain by using electrical and chemical transmitters. This means that electrical impulses that correspond to a message are passed along with the cells, and at the end of the cell these electric impulses trigger the releases of the chemicals which move and trigger an electric impulse in the next neuron cell. This passing along of messages is called transmission. Different types of neurons send different messages: Sensory neurons bring messages about sensations, like taste, touch and smell, from the relevant part of your body or to your brain. Association Neurons are present in large quantities in your brain. They gather the information from the sensory, and decide what to do about it. Motor Neurons are the third type of neurons. They control your movement. Once the association neurons have decided what to do about what the sensory neurons told them, the association neurons tell this to the motor neurons, and this is how we respond to things.
