Ari Daniel, a science reporter covering the fascinating work of neuroscientist Kamilla Souza, dives into the urgent quest to collect a baby humpback whale's brain for research. They discuss the race against time in Brazil's heat to preserve the delicate specimen and the groundbreaking insights it can provide about cetacean behavior and adaptation. The conversation also highlights the challenges faced in marine brain research, the inspiring mission to build a comprehensive brain collection, and the sheer joy that comes from such scientific discovery.
Neuroscientist Camila Sousa's groundbreaking extraction of a baby humpback whale's brain highlights the urgency and significance of cetacean research in Brazil.
Through her work, Camila aims to build Brazil's marine mammal brain collection, fostering local scientific initiatives and understanding of cetacean neurological health.

The Urgency of Brain Collection
A Brazilian neuroscientist named Camila Sousa is dedicated to studying cetacean brains, as she believes they hold essential insights into whale and dolphin biology. When an opportunity arises to collect a baby humpback whale's brain, Camila swims ashore to extract it, marking a significant achievement in her research efforts. This particular extraction represents the first of its kind in Brazil and contributes to her goal of building the largest collection of marine mammal brains in Latin America. By highlighting her commitment and the urgency of her work, we see how quickly conditions can change, emphasizing the need to act swiftly when collecting samples.
Understanding Stranded Marine Mammals
At the Orca Institute, where Camila works, teams focus on rehabilitating stranded marine mammals or conducting research on those that have died. When dolphins and whales strand themselves, it often results from entanglement with fishing gear or reactions to environmental stressors. The facility operates on a daily on-call schedule to respond to such incidents, which highlights the importance of timely intervention for study and conservation. This hands-on approach not only aids in understanding marine animal health but also provides valuable data that can help prevent future strandings.
Advancing Cetacean Research in Brazil
Camila emphasizes the significant gap in research regarding the brains of cetaceans in Central and South America, despite the presence of diverse species in these waters. Through her studies, she aims to unravel the neurological aspects of these animals, which may include investigating conditions such as Alzheimer's observed in dolphins. Camila’s efforts not only contribute to the scientific community but also inspire emerging researchers in Brazil to pursue marine science locally. Her vision encapsulates a growing movement within the country, aiming to shift the focus of scientific research from abroad to homegrown initiatives.
A year and a half ago, neuroscientist Kamilla Souza got the call she'd been waiting for: A baby humpback whale had died just offshore. She wanted its brain. That's because scientists know little about the brains of whales and dolphins off the Central and South American coasts. Studying them, like Kamilla is doing, can teach scientists about the inner workings of these animals — about their behavior and how they're adapted to living underwater. So, she has to race against time to save the brains. The heat in this area of Brazil accelerates decomposition. Minutes matter.
