Which of the following statements accurately describes the roles of both glutamate and acetylcholine in the process of learning?
1
Glutamate is primarily involved in mood regulation, while acetylcholine enhances synaptic plasticity and memory formation.
2
Both glutamate and acetylcholine act as inhibitory neurotransmitters that reduce neuronal activity and hinder learning.
3
Glutamate facilitates synaptic plasticity and long-term potentiation, while acetylcholine is important for attention and encoding new information.
4
Acetylcholine promotes muscle contraction, while glutamate is exclusively involved in sensory processing without affecting learning.
