Interneurons are a type of neuron found in the central nervous system, primarily in the brain and spinal cord. They serve as connectors or relays between sensory neurons, which receive information from the environment, and motor neurons, which send signals to muscles. Interneurons play a crucial role in processing information and coordinating responses. These neurons can be classified into various types based on their function and structure. Some interneurons are involved in reflex actions, while others contribute to complex processes like learning and memory. Overall, interneurons are essential for integrating sensory input and generating appropriate responses in the body.
