Quizplus · Accepted Answer

The lack of behavioural response to capsaicin in African naked mole rats suggests that they lack the neurotransmitter substance P, which is responsible for transmitting pain signals from the sensory neurons to the central nervous system. Capsaicin binds to the TRPV1 receptor in sensory neurons, causing the release of substance P and resulting in the sensation of pain. Without substance P, the naked mole rats do not experience the burning sensation associated with capsaicin.
