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.
1 The first of these approaches defines what is called the distal stimulus. 2  This is the energy emitted by or reflected from some object. 3  A second approach focuses on the energy falling on a receptor surface. 4  This comprises what is known as the proximal stimulus.
