What is the significance of a labeled line in the interpretation of sensory information?
What will be an ideal response?
Sensory information arriving at the CNS is routed according to the nature and location of the stimulus. Along sensory pathways, axons relay information from point A (the receptor) to point B (a neuron at a specific point in the cerebral cortex). This connection between a receptor and a cortical neuron is called a labeled line, and carries information concerning a specific sensation from receptors in a specific region of the body.
