Neural Harmony

Interesting new finding about neurotransmitters from Science Daily.

Neurons Use Chemical 'Chords' To Shape Signaling
To propagate a nerve impulse within neural circuitry, one neuron launches a burst of chemical signal called a neurotransmitter at a receiving neuron, where the neurotransmitter attaches to a specific receptor--like a key fitting a lock. That neurotransmitter-specific receptor is activated to trigger a nerve impulse in the receiving neuron.

Such nerve impulses, however, rather than being the electrical equivalent of a shotgun blast, are precisely modulated signals, like the finely shaped notes of an orchestra.
