Summary Introduction
Introduction:
As a sensory receptor cell gets stimulated, it generates an electrical signal termed as receptor potential. Receptor potential differs in size, unlike the action potentials. Receptor potential contains large size in a sensory receptor cell and can stimulate action potentials with high frequency in axons leading from the sense organ to the brain. These type of receptor potentials are able to detect touch and temperature felt on the skin.

In the process of sensory coding
Recruitment of additional neurons occurs with a weak stimulus in order to make the stimulus stronger.
The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination.
Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity.
A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.
The sensory systems are complex and have the amazing ability to respond to different types of environmental stimuli. What is one aspect of the sensory systems we have looked at (gustatory, olfactory, or visual) that you found particularly interesting and would like to know more about?
How does the frequency of action potentials in the primary sensory neuron code for stimulus intensity? (Human Physiology)
