Researchers have found that:
A)in myelinated axons,the action potential at each point in the axon gives rise to a new action potential at the next point.
B)in unmyelinated axons,positively charged ions flow down the axon at a very fast rate,causing regeneration of the action potential at each node.
C)throughout life,unused synaptic connections are pruned away as cells or their branches die and are not replaced.
D)when a nerve impulse reaches the axon terminal's button-like tip,the action potential "hops" over to the receiving neuron's dendrites.
