A brief screencast for labeled line vs. across fiber encoding.

Labeled Line:

  • 1 sensory neuron receives input from only taste receptor cells that only have 1 taste receptor type

Across Fiber:

  • 1 sensory neuron receives input from taste receptor cells that have more than 1 taste receptor type
  • 1 sensory neuron receives input from taste receptors cells that only express only 1 taste receptor type, but from many different types of taste receptor cells (each only expressing only 1 taste receptor type)

 

Update: Included another way of visualizing.
