Scientists turned to alligators, drugs and earbuds to better understand how dinosaurs might've processed sound.
Paper - Week - Journal - Neuroscience - Study
A paper published this week in The Journal of Neuroscience said the study focused on the gap in arrival time of sound to each ear, otherwise known as the interaural time difference.
The study was authored by Catherine Carr, a biologist at the University of Maryland, and Lutz Kettler, a neuroscientist at the Technische Universität München.
Carr - Lutz - Team - Alligators - Rockefeller
Carr and Lutz's team sedated 40 American alligators at the Rockefeller Wildlife Refuge in Louisiana with ketamine and dexmedetomidine. Once the animals were unconscious, the scientists inserted specially fitted earbuds. They placed electrodes on the animals' heads to record auditory neural responses to the tones and clicks played over the headphones.
The experiment discovered that alligators use similar neural mapping to that of...
