The speed of neurotransmission in the frontal lobe increases during adolescence due to the growth of Myelin
<u>Explanation:</u>
Myelin is a fatty material, rich in lipids, which coats nerve cell axons to separate them and increases the rate of datatransmission along the axon. The myelinated nerve cell axon can be associated with an electrical wire, i.e, axon covered by insulating material called myelin. Due to this action people will be more active, enthusiastic as the transmission of signals are very fast.
In other words, Myelin can significantlyincrease the speed of neurotransmission as it separates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length. The growth in myelin results in the increase of speed of transmission of electricalimpulse along the nerve cell or the axon
