What happens in a crocodile’s brain when it hears complex sounds? An international research team headed by Dr Felix Ströckens from the Department of Biopsychology at Ruhr-Universität Bochum (RUB) has provided the answer to this question. In a first, the researchers examined a cold-blooded reptile using functional MRI. They were thus able to determine that complex stimuli triggered activation patterns in the crocodile’s brain that are similar to those in birds and mammals – a deep insight into evolution. The results were published in the journal Proceedings of the Royal Society B: Biological Sciences on April 25, 2018.
