| The First Letter of Your First Name | Topic |
|---|---|
| A – D | acetylcholine |
| E – H | norepinephrine |
| I – L | dopamine |
| M – P | serotonin |
| Q – T | gamma-aminobutyric acid (GABA) |
| U – Z | histamine |
- Application of Course Knowledge: Answer all questions/criteria with explanations and detail.
- Provide a 3-5 sentence paraphrased summary of the assigned neurotransmitter purpose and function.
- Link the assigned neurotransmitter to a psychiatric diagnosis or diagnoses.
- Discuss associated symptoms of the selected diagnosis or diagnoses. Determine if each symptom is related to an excess or deficiency in the neurotransmitter.
- Identify a drug class that treats the disorder associated with the assigned neurotransmitter. Discuss whether recommended medications in this class are agonists or antagonists, and explain how the medication influences the clinical signs and symptoms (i.e., treats the diagnosis) by impacting the neurotransmitter’s activity.

Solution
The neurotransmitter GABA is inhibitory in its purpose and function. When GABA interacts with the receptors at the ends of a neuron it reduces its action potential, decreasing its ability to release neurotransmitters. When thinking about its function, a hug from a friend or loved when you are overwhelmed, sad, or afraid comes to mind. GABA does not necessarily stop all functions, just slows and calms excitatory behavior in the brain. As in the way the hug does not eliminate the fear, anxiety, or sadness, but lowers the intensity. This action makes GABA crucial in overall brain function. It is the checks and balance neurotransmitter for brain activity.
In the way that the brain initiates the pathway for the fight of flight response, the brain must also be able to return the body back to homeostasis once the threat has subsided. GABA helps with sleep regulation, reducing stress and anxiety, and seizure prevention (Zhang et al., 2024). Stahl informs us in our text that the goal of GABA at times is to mediate tonic and phasic neurotransmission, neural transmission that comes in a steady stream or waves, that does not necessarily correspond with the input the brain is receiving (2024)…………..Purchase the full NR546 Week 2 Neurotransmitters solution for $5
