Silent receptors are a type of receptor that do not trigger a sensation when stimulated, even though they are capable of detecting stimuli. These receptors do not send signals to the brain to generate a conscious perception.
The type of receptor involved in the sensation of pain is called nociceptors. These specialized nerve cells detect harmful stimuli and send signals to the brain to perceive pain.
Mechanoreceptors are the type of receptor used when feeling a pinch. These receptors detect mechanical stimuli such as pressure, vibration, and stretching. When a pinch is applied, mechanoreceptors in the skin send signals to the brain to interpret the sensation.
In specificity theory, each neuron would be tuned to fire for one colorProblems include distribution of color receptors, and the absolute number of colors we can perceive. Also, specificity theory does not account for different intensities

Each type of the principal type of sensation that we experience pain , touch, sight ,sound and so forth is called modalities of sensation. We experience these different modalities of sensation, while nerve fibers transmit only impulses. How is it that different nerve fibers transmit different modalities of sensation? 1. Each nerve tract terminates at a specific point in the CNS, and the type of sensation is determined by the point in the nervous system to which the fiber leads. So touch stimulus is carried by nerve impulses in the touch area of the brain. Similarly fibers from the eyes (retina) terminates in the "visual Corteses" of the brain, touch stimuli carried by nerve impulses in the "touch" area of the brain. 2.Moreover, each receptor organ is specialized to receive a particular type of stimuli and this is carried to the particular area of the bran.
