A Neuroscience Love Song
Doo-doo-doo-doo, do-do-do-do
Doo-doo, do-do-do-do

When you looked in my direction, I thought my heart might explode
(My heart was racing and I thought it might explode)
Because my sympathetic nervous system
Caused Norepinephrine to stimulate my sinoatrial node
When you looked in my direction, when you first looked into my eyes
(When you looked into my eyes)
My stress response diverted blood flow from my stomach and intestines and it felt like... butterflies
I knеw that I wanted to marry ya as my ventral tegmеntal area sent signals to my nucleus accumbens
And oh-oh-oh my lord, the anticipation of reward
That do-do-dopamine starts pumping

I know oxytocin is the potion of devotion
Gimme that dose of dopamine
Hold the serotonin
Still going, growing stronger all the time
I love you, and I’m never gonna change my mind

Doo doo dodo do do
When you first smiled at me, I did foolish things
(Really really really really stupid things)
Because my judgement was impaired by a reduction in activity in my amygdala and the frontal cortex of my brain
When you first smiled at me, I began to fall
(One smile and I began to fall)
And so did my serotonin levels, producing anxiety
I couldn’t eat or sleep at all
Then a year or two went by with serotonin on the rise, 'til I was feeling comfortable and calm
Now every single time we touch I get that oxytocin rush, our bond has never been so strong

I know oxytocin is the potion of devotion
Dial back that dopamine
Here comes serotonin
Still going, growing stronger all the time
I love you, and I’m never gonna change my mind

[spoken]
Lady, we’ve been together for a while now and things are starting to mellow out. But that’s okay ‘cause we can get those spark of dopamine back by experiencing new things together

Oxytocin is the potion of devotion
A little bit of dopamine
A lot of serotonin
Still going, growing stronger all the time
I love you, and I’m never gonna change my- never gonna change my- never gonna change my mind
