True to my word. Camila says there's actually very little known about the brains of whales and dolphins living in the waters off Central and South America. But mapping how those brains are wired up can teach scientists about the inner workings of these animals, about their behavior, and how they're adapted to living underwater.

It's still early days of confirming the disease, Regina. But yes, there have been signs of the hallmarks of Alzheimer's in certain dolphins. So for all these reasons, Camila's intent on gathering and studying the brains of cetaceans.

Yes, yes.

Yes, yes.

Yes, yes.

And now you know it.

And now you know it.

I do what I can. So back to Camila. She's collecting and gathering cetacean brains from this part of the world and is making real progress. She points to the 200-pound suspended guiana dolphin, a coastal species that lives in the Atlantic off Central and South America.

Yeah, well, a few years back, Camila and her colleagues used an MRI to describe the neuroanatomy and internal brain structure of a Guiana dolphin that washed ashore west of Rio de Janeiro, which was a real achievement.

Bingo. And that becomes super clear when Camila takes me to the necropsy room.

That, Gina, is the sound of knives being sharpened. The vets are dissecting another dolphin, a female that recently stranded, and a parade of organs appears on the table before me to be measured and photographed.
