Something described as neural has to do with your body's nervous system, particularly your nerves. When you stub your toe, a neural signal is sent to your brain to tell you how much it hurts.
The word neural has a Greek root, neuron, or "nerve." This scientific term is sometimes used interchangeably with neurological for anything connected with the entire nervous system. Neural pathways describe the route messages take through your nerves and spinal cord to your brain, and a neural disorder is an ailment that affects that part of your body.
