Question

Quizplus · Accepted Answer

Glutamate is one of the most abundant excitatory neurotransmitters in the CNS, responsible for the majority of fast synaptic excitation in the brain. Dopamine and norepinephrine are both monoamine neurotransmitters that are involved in modulating attention, motivation, and reward, but they are not as abundant as glutamate. GABA is the most abundant inhibitory neurotransmitter in the CNS, and endorphin is a type of neuropeptide that acts as an opioid neurotransmitter involved in pain relief and pleasure.
