How Does Your Brain Communicate?

Now that you know of the different parts and functions of the human brain, it is time to learn about how these parts communicate with each other to help your body perform and survive. A neurotransmitter is a chemical of the brain which sends and receives signals between the billions of neurons present in the brain:



In the above picture, the small red dots you see are the neurotransmitters. They are traveling through the synaptic gap between the axon (top) of the sending neuron and the dendrite (bottom) of the receiving neuron. This is how your brain communicates. These chemicals carry messages, or charges, to trigger actions and reactions in your brain.
