Ok. Before you faggots posting more and more stuff which implying I put frickin dophins above humans. The main features in the Even with sleep cycles, cetaceans do it differently. Whales and dolphins have quite large brains. Get step-by-step explanations, verified by experts. As one audience member noted, our conflicts kill and displace millions of our own species. The sequence is often repeated, with both parties having “a whale of a time.”. And researchers have found gangly neurons called Von Economo neurons, which in humans and apes have been linked to emotions, social cognition, and even theory of mind—the ability to sense what others are thinking. http://www.bbc.com/earth/story/20140909-are-dolphins-cleverer-than-dogs In bottlenose dolphins, the EQ lies between 4 and 5, in the killer whale between 2.5 and 3, in humans in the 6.5-7.5 range. Side by side you can see the difference between a human and dolphin brain. For dolphins, echolocation is the primary sense, far stronger than vision. This is likely due to the ocean environment – with few places to hide this keeps the dolphins aware at all times. Neurobiologist Lori Marino discovered that the limbic system of a whale is so large that it actually erupts into the cortex in the form of an extra paralimbic lobe. 2.4 How do dolphins communicate and do they have their own language. primitive mammalian species of the time. dolphin brain. In determining how developed a brain is, scientists consider the brain’s “encephalisation” to be a significant factor, since encephalisation – the sinuous folds on the brain’s surface – increases the amount of surface area for the cerebral cortex. Researchers developed sonar and radar inspired by the echolocation abilities of dolphins and bats. ): Dolphins, like humans, use 100% of their brains all the time. Those were the topics of discussion at a session on the ethical and policy implications of dolphin intelligence here today at the annual meeting of the American Association for the Advancement of Science (which publishes ScienceNOW). http://www.dolphincommunicationproject.org Significant encephalisation is only present in primate and cetacean brains. We may not be able to understand dolphins when they communicate, but they can learn to understand human language. To help us get to grips with this idea of other intelligent species, we take a look at the brains of one of the potentially smartest groups of animals on our planet, cetaceans. Far less is known about dolphins, Annese says. In some comparisons, brain weight to body weight ratio is used, but it is now more common to use the so-called Encephalization Quotient (EQ), which is calculated as: EQ = brain weight / (0.12 * (body weight (2/3))) (brain weight, divided by 0.12 time the body weight to the power (2/3)). http://news.nationalgeographic.com/news/2006/05/060508_dolphins.html. But it's not just size that matters. Dolphins were never bred for specific attributes — they have evolved without human interference. To back up this idea of intelligence correlating with brain size, sperm whales (and some dolphin species) have displayed certain abilities associated with high intelligence – abilities that even our best technology struggles to compare to. We think of intelligence as the harnessing of technology, and the ability to think abstractly about striving to achieve growth and progress. Marino bases her argument on studies of the dolphin brain.

Technically, this is known as “unihemispheric slow-wave sleep.” During sleep, one hemisphere of the brain shuts down, and the dolphin’s opposite eye closes. In bottlenose dolphins, the EQ lies (ch.

She showed graphic video of dolphins being drowned and stabbed as the waters turned red with blood in places such as the Japanese town of Taiji. Morgane, M.S. agree that the size should be viewed in relation to the body Morgane (1992) Human Brain Vs Dolphin Brain - Running head HUMAN BRAIN VS DOLPHIN BRAIN 1 Human Brain Vs Dolphin Brain Marcus D Williams ITT Technical Institute SC4730, Running head: HUMAN BRAIN VS DOLPHIN BRAIN, The human brain can be so complex and diverse, we sometimes gratify ourselves as the, most intelligent animal, the most intelligent creature. is used, but it is now more common to use the so-called Sensort Abilities of Cetaceas - Laboratory and Field Evidence, 59-70 Ridgway (1986b) Now that scientists know so much about how dolphins think and feel, she said, they should use that data to build a bridge to the public—a big theme of this year's meeting. Trained dolphins are known to comprehend hundreds of words, and respond to specific gestures.
