Explaining the Logical Nature of Electrical Solitons in Neural Circuits

Introduction Memory-based activities within a brain depend on neurons being able to generate arbitrary Boolean logic. A single neuron may be modeled as follows: Inputs may be assumed to be excitatory and inhibitory positive ions, commonly termed neurotransmitters, usually coupled to receivers located along dendrites; outputs are excitatory or inhibitory neurotransmitter ions from the tips of an axon. Dendritic receivers are negative inside relative to outside because of small charge transfers through the membrane. Thus positive neurotransmitter ions are attracted to negative receivers and can trigger an electrical pulse.
