Which of the following best describes 'interneurons'?

Interneurons play a crucial role in the nervous system as they are primarily responsible for processing information within the central nervous system. They act as relay stations and are essential for integrating sensory input and motor output, making them involved in reflexes and higher-order functions. Unlike sensory neurons that detect environmental stimuli or motor neurons that transmit signals to muscles, interneurons facilitate communication between different types of neurons. Their ability to connect various neurons allows for the complex processing of information and coordination of reflexes, which is vital for proper functioning of the nervous system.
