Final answer:
The neurotransmitter related to the traits of extra erosion is glutamate.
Step-by-step explanation:
The neurotransmitter related to the traits of extra erosion is glutamate. Glutamate is the most prevalent excitatory neurotransmitter in the central nervous system (CNS) and plays a key role in both normal excitatory neurotransmission and modulating both normal and constructive plasticity as well as excitotoxic biochemistry. Glutamate overstimulation can lead to excitotoxicity, which can cause damage to neurons and result in extra erosion.
