the brain responsible
for happiness are the
hypothalamus, nucleus
accumbens, and
septum.
• These “pleasure” regions of the brain release
neurotransmitters, endorphins, and dopamine that
result in the feelings we know as happiness and joy.
13. Fun Facts
• Phenylethylamine (PEA), which occurs naturally in the brain
stimulating happiness, can also be found in chocolate.
• Levels of testosterone in women increase when they are in
love but decreases in men.
• Most changes in the tissues of the brain are in implicit
(emotions, body sensations, relationship paradigms, and
our sense of the world) memory.
• Falling in love appears to reduce serotonin levels in the
blood in a similar way to obsessive-compulsive disorders
• MRI scans have shown that love lights up parts of the brain
linked to the reward system that can cause drug addiction
