A yr and a half in the past, neuroscientist Kamilla Souza obtained the decision she’d been ready for. A child humpback whale was adrift simply offshore, within the waters off southeastern Brazil. It had died — and he or she needed its mind.
“It is like Alice in Wonderland,” says Souza, the founder and scientific director of the Brazilian Neurobiodiversity Community. She riffs off the basic line “Give me the pinnacle!”
Souza has been fascinated by the brains of marine mammals ever since she was younger. She says there’s little or no recognized in regards to the brains of whales and dolphins residing within the waters off Central and South America. However finding out them can educate scientists in regards to the inside workings of those animals — about their conduct and the way they’re tailored to residing underwater.
By the point Souza and her colleagues from the Instituto Baleia Jubarte arrived on the scene by boat, the whale had washed ashore a tiny island — they usually had an issue — they might solely get so shut with out operating aground.
“You take a look at the scenario,” she remembers, “and also you say, ‘OK, I would like it. I am going to get this one it doesn’t matter what.’ I did not have time to suppose. You simply need to go.”
So Souza grabbed her scalpel and noticed, and he or she swam to shore. Soaking moist, she obtained out her instruments and managed to extract the contemporary, intact mind from the lately deceased whale. She was elated.
“It was the primary extraction of a whale mind right here in Brazil,” she says proudly.

She then swam again to the boat with the mind nestled in a protecting container.
Souza introduced it again to her lab the place it joined the ranks of what she says has turn out to be the biggest assortment of whale and dolphin brains in all of Latin America.

A race towards time
Contained in the necropsy room, a few veterinarians sharpen their knives to dissect one other dolphin that lately stranded close by. A parade of organs seems on the desk to be measured and photographed — the guts, a kidney, the uterus.
Souza walks round to the pinnacle. “So right here now we have the cranium,” she observes. However, she says, “there is no such thing as a mind.” That is as a result of it is mainly liquefied.
The warmth on this space of Brazil accelerates decomposition, so minutes matter. For this reason typically, Souza has to extract the mind from a freshly deceased animal proper on the seaside. “Now we have to cope with folks, animals, the climate,” she says with amusing. “Generally it is raining.”
Souza is relentless, says Daniela Teles, one of many Orca Institute veterinarians. “Kamilla can discover the treasure that’s hidden inside all of this flesh and carcass and odor,” she says. “She finds the mind and research it. And it is superb.”

A fridge crammed with brains
Souza opens up a normal-looking fridge in her workplace to point out off a number of of these treasures. She has a mind from a pygmy sperm whale, numerous dolphin species and extra. She takes the lid off the biggest plastic container to elevate a hefty-looking mind out of the liquid preservative. It is from that child humpback she swam ashore to dissect and it is twice the dimensions of a human mind.
“So this mind is big,” Souza says with admiration. “I would like the 2 arms to carry this mind.”
There earlier than her is, arguably, she says, the convoluted essence of a humpback whale — the factor that lets it swim and sing and a lot extra.
Given her worldwide coaching, her entry to understudied species, and all she’s completed, Souza says she’d doubtless have the ability to work overseas. “However I am right here as a result of I wish to be,” she says. “I wish to do this type of analysis right here. My concept is to cowl as a lot of the Brazilian coast as I can. I wish to carry this data to Brazil. I wish to encourage Brazilian folks to do one thing new, to do one thing particular.”
A type of folks is Heitor Mynssen, Souza’s Ph.D. pupil. He is growing a pc device to mannequin quite a lot of cetacean brains in 3D. He, too, needs to contribute to the sector from right here. “We do not have to at all times depend on different international locations,” he says. “We will really do it on our personal, and present the world that we will really do good science. With the ability to be a scientist in Brazil, it seems like a part of me.”
João Marcelo Ramos Nogueira, the manager director of the Orca Institute, is delighted to have Souza on his staff. “As soon as Kamilla got here in,” he says, “we had the likelihood to develop the evaluation and [do] extra analysis.”
When Souza will get the possibility to look out on the ocean and think about the trajectory that introduced her to this second, she says, “I believe that I did the appropriate factor as a result of I am tremendous pleased with my work and with the issues that I am doing for my nation and for me as a researcher.”
Souza says she has little doubt that the kid she was once could be pleased with the place she ended up.
