What is Action Potential

Handbook of Research on Synthetic Emotions and Sociable Robotics: New Applications in Affective Computing and Artificial Intelligence
An action potential, also called a neural impulse or spike, is a stereotypical excursion in the membrane potential caused by the opening and closing of ion channels in a cycle of positive feedback and recovery. An action potential is triggered when a membrane is sufficiently depolarized from its normal negative resting potential; positive feedback causes a rapid repolarization in the positive direction, after which there is a relatively slow return to a potential slightly more negative than the resting potential, followed by a gradual return to resting potential. Action potentials propagate down axons without attenuation to convey information to other neurons.

Robots React, but Can They Feel?

Abstract
This chapter addresses the “Hard Problem” of consciousness in the context of robot emotions. The Hard Problem, as defined by Chalmers, refers to the task of explaining the relation between conscious experience and the physical processes associated with it. For example, a robot can act afraid, but could it feel fear? Using protophenomenal analysis, which reduces conscious experience to its smallest units and investigates their physical correlates, we consider whether robots could feel their emotions, and the conditions under which they might do so. We find that the conclusion depends on unanswered but empirical questions in the neuropsychology of human consciousness. However, we do conclude that conscious emotional experience will require a robot to have a rich representation of its body and the physical state of its internal processes, which is important even in the absence of conscious experience.
