Photoreceptors in the human eye are depolarised during darkness and become hyperpolarised in response to the light stimulus.

Vedclass · Answer

(C) The correct statement is $C$. Photoreceptors in the human eye are unique because they are the only type of sensory cells that are relatively depolarised (about $-35 \ mV$) when at rest (i.e.,in the dark),and they become hyperpolarised (to about $-70 \ mV$) in response to an adequate light stimulus. Nociceptors respond to potentially damaging stimuli that result in pain,not pressure. Meissner's corpuscles are a type of mechanoreceptor responsible for touch sensitivity,not thermoreception. Receptors generally produce graded potentials known as receptor potentials.
