Neurotransmitters

Question 1

Dopamine (Psychotic/ mood disorders)

Answer 1

It is known as a reward chemical since it is responsible for the pleasure-reward system in the brain. Additionally, it is named a motivation molecule since it gives us the focus and drive we need to be productive.
Neurotransmitters such as dopamine allow messages to travel between nerve cells in the brain. When they are disrupted, the messages either return to the transmitter or are lost altogether. The consequence of interrupted neurotransmitters can result in depression, anxiety and other mental health conditions as well as a tendency toward substance dependency.

Question 2

Serotonin (Mood Disorders)

Answer 2

Associated with mood, sleep, hormone regulation and emesis

Question 3

GABA

Answer 3

GABA is considered an inhibitory neurotransmitter because it blocks, or inhibits, certain brain signals and decreases activity in your nervous system. When GABA attaches to a protein in your brain known as a GABA receptor, it produces a calming effect. This can help with feelings of anxiety, stress, and fear.
GABA is an inhibitory neurotransmitter, which means that it weakens or slows down signals. Because of its inhibitory function, GABA plays an important role in anxiety. When nerve signals fire too quickly and carry anxiety-inducing signals, GABA acts to slow the signals down, reducing overwhelming feelings of anxiety

Question 4

Acetylcholine

Answer 4

low acetylcholine levels have been linked to learning and memory impairments
