    Fish intelligence - Wikipedia

    Fish typically have quite small brains relative to body size compared with other vertebrates, typically one-fifteenth the brain mass of a similarly sized bird or mammal. However, some fish have relatively large brains, most notably mormyrids and sharks, which have brains about as massive relative to body weight as birds and marsupials. The chatterbait has been hammering fish since the first day it stormed onto the scene from Z-Man. There’s no debating it flat out catches fish. Chatterbait trailers, however, have been up for ... We therefore used artificial selection on relative brain size in a live-bearing fish, the guppy (Poecilia reticulata), to provide a direct test of the prediction that increased brain size is genetically associated with increased cognitive ability but that a large brain is also traded off against gut size and results in reduced reproductive ...

    Brain Size Study Involving Guppies Suggests High ...

    Guppies, as it turns out, aren’t as dumb as they look. They’re able to learn, and show rudimentary ability to count. Researchers from Uppsala University in Sweden were able to use their numerical abilities to test whether brain size affects intelligence in these simple fish. Albert Einstein may be a perfect example that it may not be overall size that matters, but size of certain sections beyond just the frontal lobe. ­Einstein, for example, had a perfectly normal-size brain, but certain parts of it were larger than normal, including the inferior parietal region, which affects mathematical thought [source: Wanjek]. The fish brain USB drive was described as having multiple electronic components connected to the brain of a dead fish, which to us, doesn’t makes any sense at all. After some quick seach on Google using ‘fish brain USB’ as the keyword, it led us back to the original source of the image on Twitter.

The team found no difference in the size of various brain regions between groups of fish. “That was a surprising finding,” said Axelrod. Other scientists, for instance, have found bottom-feeding sharks have more developed olfactory bulbs than open water species whose larger cerebellum regions probably reflect different foraging behaviours.

    Single gene controls fish brain size and intelligence

    A single gene called Angiopoietin-1 (Ang-1) drives brain size and intelligence in fish according to a new study by researchers at UCL, Stockholm University and University of Helsinki. Discuss language and brain size. Discuss cortical expansion in higher species. (Images with the permission of Dr. Wally Welker of the Mammalian Brain Collection at the University of Wisconsin) The total surface area of the human cerebral cortex is about 2,500 cm 2. This is about the size of a pillow case (about 40 cm by 62.5 cm). While the pig brain is considerably less in weight, weight does not determine the ability to think or solve problems. Swine are remarkably adept at problem solving and are considered pretty darn smart by those who work with them. Cattle, horses, a...

The finding may provide clues about how fish and other creatures will respond to mounting ... Dolphins have the highest brain to body mass ratio of all cetaceans. Sharks have the highest for a fish, and octopuses have the highest for an invertebrate. Humans have a higher brain to body mass ratio than any of these animals. It is a trend that the larger the animal gets, the smaller the relative brain size gets. After the baby is born, the brain continues to grow very quickly. In the first year of life, it grows by another 175%, and in the second year of life, by another 18%. After age 2, changes and growth occur throughout childhood but the total size of the brain only increases by another 21%.

    Brain size is sometimes measured by weight and sometimes by volume (via MRI scans or by skull volume). Neuroimaging intelligence testing can be used to study the volumetric measurements of the brain. One question that has been frequently investigated is the relation of brain size to intelligence. As brain size increases from 1356 to 1383 cm 3 across the three racial groups, 37 musculoskeletal traits vary accordingly with a remarkable mean r = .94, ρ = .94. These changes occurred on both cranial traits (temporalis fossae, postorbital constrictions, mandibles, dentition, neck muscle attachments), and postcranial traits (pelvic widths ... The cerebrum, also known as the telencephalon, is the largest and most highly developed part of your brain. It encompasses about two-thirds of the brain mass and lies over and around most of the structures of your brain. The word cerebrum comes from Latin cerebrum, meaning "brain."
