The communication network in your brain is a multi-trillion maze of connections capable of performing 20 million-billion calculations per second. How does this network operate? There are three major players: Neurons, which power the message, Neurotransmitters, which create the message and Receptors, which receive the message.
Within the cell body of a neuron, many different types of chemical neurotransmitters are manufactured and shipped out to the end terminals of the axon. Here they're stored in bubble-like structures (vesicles), where they wait to cross over the space between neurons, called the synapse (from the Greek word for "junction").
The bioelectric impulse signals the vesicles to burst and the neurotransmitters to spill out across the synapse, where they're caught by receptor molecules on the membrane of the target neuron's dendrites.
Dopamine is the neurotransmitter needed for healthy assertiveness and sexual arousal, proper immune and autonomic nervous system function. Dopamine is important for motivation and a sense of readiness to meet life's challenges.
One of the most vulnerable key neurotransmitters, dopamine levels are depleted by stress or poor sleep. Alcohol, caffeine, and sugar all seem to diminish ...
