Open Up Your Heart and Let the Sunshine In (Sisters' Cover)

Lyrics

[Intro]
Premise: Auditory stimuli, specifically major key structures at 90 beats per minute, can induce significant and measurable neurochemical change.

[Verse 1]
Smiley was a grumbler, he was a lonely soul
Subject exhibits symptoms of chronic dysthymia. Elevated cortisol.
He'd never let the sunshine in, he'd stay out in the cold
A state of homeostatic imbalance, characterized by reduced serotonin and dopamine receptor activity.

[Chorus]
So open up your heart and let the sunshine in!
The ventral striatum is now releasing dopamine. A reward response is initiated.
Face it with a grin, smilers never lose
Zygomaticus major muscle activation correlates with positive affect.
And frowners never win, so open up your heart and let the sunshine in!
A successful cascade in the mesolimbic pathway is observed.

[Verse 2]
I went to see a wise man, it was back in 1949
Subject sought external counsel to resolve persistent cognitive dissonance.
He said you'll feel a whole lot better if you'd only change your mind
Neuroplasticity confirms the potential for structural and functional change in the prefrontal cortex based on conscious redirection of thought.

[Chorus]
So open up your heart and let the sunshine in!
The ventral striatum is now releasing dopamine. A reward response is initiated.
Face it with a grin, smilers never lose
Zygomaticus major muscle activation correlates with positive affect.
And frowners never win, so open up your heart and let the sunshine in!
A successful cascade in the mesolimbic pathway is observed.

[Bridge]
It’s not just a song, you see. It’s a circle that we make.
Musical entrainment creates shared emotional resonance. A bio-feedback loop.
The drone holds the floor, and the other voices wake.
The low-frequency hum stimulates the vagus nerve, inducing a parasympathetic state.
Even Mrs. Patterson knows the words now. She sings them by the gate.
The release of oxytocin during communal vocalization strengthens social bonds.

[Chorus]
So open up your heart and let the sunshine in!
Maximum observable dopamine release!
Face it with a grin, smilers never lose
And frowners never win, so open up your heart and let the sunshine in!

[Outro]
Let the sun shine in...
Metaphorical sunshine, of course. Not literal photons...
Let the sun shine in...
