Higher neuron densities in the cerebral cortex and larger cerebellums may limit dive times of delphinids compared to deep-diving toothed whales.
Autor: Sam H Ridgway, Robert H Brownson, Kaitlin R Van Alstyne, Robert A Hauser
Publikováno v: PLoS ONE, Vol 14, Iss 12, p e0226206 (2019)
Since the work of Tower in the 1950s, we have come to expect lower neuron density in the cerebral cortex of larger brains. We studied dolphin brains varying from 783 to 6215g. As expected, average neuron density in four areas of cortex decreased from

Publikováno v: PLoS ONE, Vol 7, Iss 10, p e47478 (2012)
In dolphins, natural selection has developed unihemispheric sleep where alternating hemispheres of their brain stay awake. This allows dolphins to maintain consciousness in response to respiratory demands of the ocean. Unihemispheric sleep may also a

Apneustic anesthesia ventilation improves pulmonary function in anesthetized bottlenose dolphins (Tursiops truncatus)
Autor: Carolina R. Le-Bert, Alex Bukoski, John Downs, David S. Hodgson, Lori Thombs, Sam H. Ridgway, James Bailey
Publikováno v: Frontiers in Veterinary Science, Vol 11 (2024)
IntroductionUse of mechanical ventilation during general anesthesia is a necessary practice in the anesthetization of small cetaceans as spontaneous ventilation fails to provide adequate gas exchange. Currently available methods of ventilation do not

Multiple techniques have been used for estimating age in bottlenose dolphins (Tursiops truncatus). The longest established technique is via counts of growth later groups (GLGs) in the longitudinal section of an extracted mandibular tooth. Previous st

Sights and sounds of dolphins, Tursiops truncatus, preying on native fish of San Diego Bay and offshore in the Pacific Ocean
Autor: Sam H. Ridgway, Dianna S. Dibble, Mark Baird
For the first time, dolphins wearing video cameras were observed capturing and eating live native fish. While freely swimming in San Diego Bay, one dolphin caught 69 resident fish, 64 demersal, 5 near surface, while the other caught 40, 36 demersal a

Bottlenose dolphins (Tursiops truncatus) have a worldwide distribution in temperate and tropical waters and often inhabit estuarine environments, indicating their ability to maintain homeostasis in low salinity for limited periods of time. Epidermal
