Scrabble?! ELECTROTONIC

Definitions of ELECTROTONIC in various dictionaries:

In physiology, electrotonus refers to the passive spread of charge inside a neuron. Passive means that voltage-dependent changes in membrane conductance do not contribute. Neurons and other excitable cells produce two types of electrical potential: Electrotonic potential a non-propagated local potential, resulting from a local change in ionic conductance (e.g. synaptic or sensory that engenders a local current). When it spreads along a stretch of membrane, it becomes exponentially smaller (decrement). Action potential a propagated impulse.Electrotonic potentials represent changes to the neuron's membrane potential that do not lead to the generation of new current by action potentials. Neurons which are small in relation to their length, such as some neurons in the brain, have only electrotonic potentials (starburst amacrine cells in the retina are believed to have these properties); longer neurons utilize electrotonic potentials to trigger the action potential. The electrotonic pot
