What is the relationship between seratonin and dopamine in the brain? by Connie b. Dellobuono
Answer by Connie b. Dellobuono:
Both neurotransmitters affect learning and mood. From a functional standpoint, serotonin is an inhibitory neurochemical – meaning it makes it more likely that neurons will not fire. Dopamine acts as an excitatory neurochemical – making it more likely that neurons will fire – but it can also have certain inhibitory effects.
The effects of serotonin and dopamine have a great deal of interplay. Balancing these two brain chemicals is key to optimal mood and cognitive function.
For example, we know that high serotonin can help to diminish appetite cravings. Conversely, high dopamine levels signal a greater desire to eat. This neurotransmitter is the reason why we feel (sometimes very intense) pleasure when consuming foods.
Imbalance in Serotonin and Dopamine is seen in Bi-polar disorders.
