    “

    We're not just electrical beings—we're chemical beings too. Emotions aren't just happening in our heads; they're literally molecules flowing through our bloodstream, acting as a giant communication network for the entire body.

    Opening & Setting the Stage

    0:00

    Blythe: Hey everyone, welcome back to another personalized episode from BeFreed-I'm Blythe, and I am absolutely buzzing to dive into today's topic with my brilliant co-host Nia!

    0:11

    Nia: Hey there! I'm Nia, and honestly, when I saw what we were exploring today, I literally got goosebumps. We're talking about Dale's criteria for neurotransmitters, and trust me, this is way more fascinating than it sounds.

    0:24

    Blythe: Right? I mean, when you first hear "Dale's criteria," it sounds like some dry scientific checklist, but what we're really talking about is how scientists figured out the secret language of our brains. Like, how do you even prove that a tiny molecule is actually carrying messages between neurons?

    0:42

    Nia: Exactly! And what's so cool is that this connects to everything-from why we feel emotions in our bodies to how a wooden splinter in a king's eye revolutionized brain science. We're basically uncovering the detective work behind understanding our own consciousness.
