Vertebrates and invertebrates use very different strategies to increase conduction velocity of neurons.
Saltatory conduction is metabolically more efficient than electrotonic conduction.
Refer to the circuit diagram of the neuromuscular junction. We know that there are GABA A and GABA B receptors and that the mechanism for inhibition is different for each receptor. Receptors are responsible for filtering, transduction, amplification, and activation. Describe the phenomenon called range fractionation by sensory afferents. In your own words, explain range fractionation and note the significance of this phenomenon for the vertebrate nervous system.
