Question

These neurotransmitters are often described as neuromodulators because of their role in modifying ongoing cortical activity

a) amino acid neurotransmitter
b) amine neurotransmitters
c) neuropeptides
d) gas neurotransmitters

Answer 1

Neuromodulators, such as amino acid neurotransmitters and neuropeptides, modify ongoing cortical activity. Amino acid neurotransmitters have their own systems and receptors and are eliminated from the synapse by reuptake. Neuropeptides are neurotransmitter molecules made up of chains of amino acids and can act as hormones in the body.

Step-by-step explanation:

Neuromodulators are neurotransmitters that modify ongoing cortical activity. One group of neuromodulators are amino acid neurotransmitters, which includes glutamate, GABA, and glycine. These neurotransmitters have their own systems and receptors, and they are eliminated from the synapse by reuptake. Another group of neuromodulators are neuropeptides, which are neurotransmitter molecules made up of chains of amino acids. Neuropeptides are often released at synapses in combination with another neurotransmitter and can act as hormones in other systems of the body.
