How do we think?
Brain cells communicate with each other through an electrochemical process. Every time you think, learn or communicate, a neuron (brain cell) in your brain sends a nerve impulse down its axon. The axon of one brain cell makes multiple thousands of connections with many thousand other brain cells. The point where one brain cell connects to another is called a synapse.

When the nerve impulse (electro-magnetic bio-chemical message) surges down the axon, it is fired across the synaptic gap via a chemical messenger called a neurotransmitter into the dendrite of the receiving brain cell. The nerve impulse then travels along the axon of this brain cell, across the synaptic gap to another brain cell and so on. When a neuron activates (“fires”) another in this way, it’s like a switch being turned on. Neurons fire like a line of falling dominoes. This activity is the process that creates the intricate pathway of thought, also called memory traces or neural pathways.
