Neurons that normally receive incoming stimuli are called sensory neurons, also known as afferent neurons.

Here's a breakdown:

* Sensory neurons are specialized cells that detect changes in the environment, such as light, sound, touch, temperature, or chemical signals. They then convert these stimuli into electrical signals that are transmitted to the central nervous system (CNS) for processing.

* Afferent neurons simply refers to neurons that carry information towards the central nervous system, which includes sensory neurons.
