Energies in the Neuromythograph refer to neurotransmitters. These are chemical signals that neurons communicate information to other neurons and glial cells. Exactly what the semantic meaning of these signals are is an ongoing area of neuroscience research. The Neuromythograph characterizes each energy with an archetypal character, representing a theory of the role of the neurotransmitter in the brain.
Energies bind with [[receivers]], that modulate the message on the receiving end.
