Substances that facilitate or mimic the activity of a neurotransmitter system are known as agonists. These can include drugs, hormones, or natural compounds that bind to neurotransmitter receptors and activate them, producing effects similar to those of the natural neurotransmitter. For example, morphine acts as an agonist for the endorphin system by binding to opioid receptors, leading to pain relief. Additionally, some substances can enhance neurotransmitter release or inhibit their reuptake, further amplifying their effects in the synaptic cleft.
Valium (diazepam) is in the benzodiazepine family of medications. Benzodiazepines bind to GABA (gamma-amino-butyric acid) receptors, which are the major inhibitory neurotransmitters in the CNS (central nervous system). Thus, Valium facilitates an increase in GABA activity.
A substance that promotes the activity of a neurotransmitter is called an "agonist." Agonists bind to neurotransmitter receptors and mimic or enhance the effects of the natural neurotransmitter, thereby increasing its action in the brain or nervous system. For example, morphine acts as an agonist for endorphins, promoting pain relief and feelings of euphoria. This interaction can lead to various physiological and psychological effects depending on the neurotransmitter involved.
Acetylcholine functions as both a neurotransmitter in the nervous system, where it is involved in transmitting signals between nerve cells, and as a neuromodulator that influences the activity of other neurotransmitter systems. It plays a critical role in muscle contraction and movement, as well as in memory, learning, and attention.
GABA is a neurotransmitter, it is the primary inhibitory neurotransmitter of the nervous system
In the nervous system, permissive action refers to one neurotransmitter enhancing the effect of another neurotransmitter. This occurs when one neurotransmitter prepares receptors to be more responsive to another neurotransmitter, allowing for a more amplified response.
After a neurotransmitter travels through the synaptic cleft, it binds to receptors on the receiving neuron, which can either excite or inhibit the receiving neuron's activity. This process helps transmit signals between neurons in the brain and nervous system.

This neurotransmitter is responsible for the "reward" properties of electrical stimulation of the midbrain or limbic system?
The vagus nerve primarily releases acetylcholine, a neurotransmitter that plays a crucial role in the parasympathetic nervous system. Acetylcholine facilitates various bodily functions, including slowing the heart rate, promoting digestion, and regulating other involuntary processes. This release helps maintain homeostasis and supports the body's "rest and digest" responses.
Most CNS depressants activate a neurotransmitter called gamma-aminobutyric acid (GABA), which helps decrease brain activity.
