What stimulates the brain to love?

Dopamine, serotonin, and norepinephrine levels rise during emotional states, which increases the activity of brain circuits dependent on these neurotransmitters.

The release of dopamine and serotonin affects how we feel. Human sensations and coordination are aided by dopamine. The excitation state is strong with very high dopamine levels, and this is a brain function. Dopamine can exacerbate anxiety in a different brain function.

Because of this, emotions raise the levels of the neurotransmitters dopamine, serotonin, and norepinephrine in the brain, which increases the activity of the brain circuits that rely on these neurotransmitters.

Therefore, these are the neurotransmitters that stimulate the brain towards feelings. So, option (B) is the correct answer.
