neurotransmitter

What: "A typical neurotransmitter is like a letter. It sends information. You keep paper in your house for when you need to write a letter, then you send it (and could watch it travel to its destination, if you wanted to) and it is received by one person."

What: "As long as serotonin is flowing between your neurons, you are confined to this 3D world of the here and now, in this particular body, in this ego, which you wake up to every day. The neurotransmitter is like a radio antenna tuned into a specific dimensional frequency. There are other antenna's which transmit higher dimensional data."

What: "Enter oxytocin. This neurotransmitter is like an invisible cord that creates unity in relationships. It's released during orgasm and helps couples to create an emotional bond. In theory, the more sex you have, the greater the bond. Even when you kiss or hug a loved one, oxytocin levels can reverberate through your body like a Keith Moon drum roll."

What: "This neurotransmitter is like the sparking action of a spark plug. ..... Believe it or not over 1 million messages travel within one second period of time from one cell to the next. So you can see how important it is to build up your serotonin level if it is low. It is absolutely imperative."

What: "It's the shape. Think of the childrens' toy in which you must push correctly shaped blocks, like circles or triangles, through a corresponding hole. Each neurotransmitter is like a puzzle piece, and it flows across the gaps from one neuron to the next where it looks for the correctly shaped hole in which to bond. Thus, with the correct pattern of neurotransmitters cells can communitcate with one another."

What: "When the brain sends a message via a neurotransmitter there has to be a corresponding neuroreceptor to receive the message. The neurotransmitter is like a radio-wave and the neuroreceptor is like a radio station. The frequencies have to match up to be picked up by the radio station."

What: This is the commonest analogy on the web for this idea. It should be expanded a bit, but I'm not sure how. The neurotransmitters themselves, serotonin, acetyl-choline are the keys. They are released from one side of a synaptic gap. They diffuse, very rapidly across the gap and bind specifically with membrane proteins(locks) other side of the gap. There are millions if not billions of molecules diffusing across such a gap. Image a million(to mix this metaphor) bees flying between 2 straight parallel fences at the same time. This image is a good approximation for how neurotransmitters diffuse across a gap. The molecule as puzzle piece is a useful association. The 3-d shape of a molecule can vary tremendously. Look at serotonin molecule in the link. Visualize the molecule without the OH-- hydroxyl group on the left. It is now a different key with a missing tooth, that doesn't fit very well into it's designated lock.

What: "Loaded with the neurotransmitter acetylcholine, the vesicles are like a battery of fireworks poised to launch a neurotransmitter barrage into the synaptic cleft - where this amplified signal will in turn energize the adjacent muscle fiber. In the last step, what biologists call a "fusion event," the calcium ions trigger some of the vesicles to fuse with the cell membrane and open outward, allowing their payload to escape."
