Question

Quizplus · Accepted Answer

The type of neuron that does not develop normally in narcolepsy is hypocretin neurons. These neurons produce hypocretin, also known as orexin, which plays a key role in regulating sleep-wake cycles. The loss of these neurons is associated with excessive daytime sleepiness in narcolepsy. Myelinated and nonmyelinated neurons refer to the presence or absence of myelin, a fatty substance that surrounds and insulates axons. Afferent neurons transmit signals from sensory receptors to the central nervous system. However, none of these types of neurons are specifically linked to narcolepsy.
