The stimulus energy must occur within the receptor's receptive field. The stimulus energy must match the specificity of the receptor. A generator potential in the associated sensory neuron must reach threshold. The stimulus energy must be converted into the energy of a graded potential. called a transduction potential.
For instance, our eyes receive and convert light waves into electrical energy which are transmitted to the visual cortex of the brain to create the sensation of vision and subsequently leading to perception. But each sense receptor requires a minimum level of energy to excite it before perception can take place.
