Dolphins Use What Percentage Of Their Brain

Dolphins Use What Percentage Of Their Brain – A dolphin brain is the second most powerful and complex brain of any animal (after the human brain, of course). Intelligence can be defined as a measure of the brain’s ability to process information that solves problems and promotes survival. Measuring the intelligence of animals that evolved in water can be quite different from those that live on land, because the challenges required to survive in water are different from those on land. There is much debate about the “intelligence”, “cognitive learning ability” and “sociality” of dolphins. Dolphins have big brains Animals with large brains, such as humans, chimpanzees and dolphins, have many similarities. Due to neurological development, they tend to live longer They form stable communities that include aquatic social groups In childhood they show complete trust in their parents

There are no specific IQ tests available to measure dolphin intelligence In this way it is impossible to accurately estimate the intelligence level of this animal But another way to measure intelligence is to determine the brain size ratio, which is defined as the ratio between the actual brain and the brain weight of animals of a given size. This is called “brain quotient” or EQ The brainstem quotient is the measure of all species

Relative brain size, which works as the ratio of actual brain weight to estimated brain weight for a given species relative to body weight.

This scale shows that the higher the number, the higher the IQ Human EQ is 7.0 Apes, elephants, chimpanzees and tigers have an EQ of around 1.8-2.3, meaning they have smaller brains than humans relative to their body size. Dolphins have an EQ of 4.2, the closest EQ ratio to humans

This graph plots the axis of six structures against the “brain core” (medulla, pons, midbrain, and thalamus). Each visible area of ​​the cerebral cortex, such as the visual cortex, other primary sensory cortex, and even the parietal or frontal cortex, has its own index of attention to parts of the human cortex. possibly | Expect a simple standard, such as a chimpanzee brain three times larger, and predict that deviations from this standard must represent idiosyncratic selection or adaptation. However, the doubling rate is not always the value of the correlation between the parts of the brain, it occurs only in certain situations where the ratio of the allometric data of the two parts is the same. If the frontal cortex is allometric with the rest of the cortex, then the frontal cortex will account for a larger portion of the rest of the cortex because the cortex grows in absolute terms. However, when compared to other primates, the volume of the frontal cortex in the human brain can be estimated, but out of scale.

This appears to be a common sense level The more the cortex folds, the more area the brain can handle

It is used for information processing The only animal with a cerebral cortex that folds larger than humans is the dolphin Some scientists believe that the main reason the brain is so large is because it uses information from the dolphin’s sophisticated echolocation, or biosonar, system. But there is no evidence to support this belief The widely accepted theory is that larger brains evolved to support cognitive abilities, as seen by bottlenose dolphins and dolphins. They can remember events and learn concepts by changing their behavior based on past experiences or training They can communicate with each other, manage relationships and raise children in a collaborative process Not only can they understand the words (signs) of sign language, but they can also interpret the written (sound) order of the language. This understanding of grammar shows great intelligence Whistle signatures made by dolphins (see the Vocalizations chapter of this website) provide further evidence that dolphins have self-awareness, or the ability to sense “self” and know that a person exists as a person. Self-awareness resides in the prefrontal cortex

Perhaps the most obvious difference between our brains and that of dolphins and all toothed whales is that they have an area dedicated to echolocation. Dolphins have sonar, a skill or superpower known as echolocation Sound travels better in water than light, so it makes sense that dolphins use sound to hear their surroundings The ability to echolocate is amazing; They can see amazing information about everything around them They use echolocation to hunt and navigate even in dark or murky water Dolphins can see each other’s bodies and hear the echolocation clicks (squeaks and pulsing calls) of other dolphins to see what they are seeing.

The brains of whales and dolphins contain brain cells called spindle neurons. These are related to higher-order skills, such as cognition, memory, reasoning, communication, perception, adaptation, problem solving, and understanding. So they seem to have deep thoughts! Not only that, but the part of their brain that processes emotion (the limb) appears to be more complex than ours. Neuroscientist Lori Marino explains: “A dolphin is not really a dolphin; Being a dolphin means being part of a complex social network…even larger than humans

) with a total brain weight of 1,500-1,700 grams It is slightly larger than a human (1,300-1,400 g) and four times the size of a chimpanzee (400 g).

Some members of the toothed whale superfamily, the dolphinoid superfamily (dolphins, porpoises, beluga whales, and narwhals), have higher brain-mass ratios (not brain mass ratios) than modern humans and other animals.

Encephalization coefficients vary greatly between species The EQ for La Plata dolphins is about 1.67; 1.55 for Ganges River Dolphins; 2.57 for orca; 4.14 bottle dolphin; and 4.56 for Turkish dolphins

The scientists compared giant dolphins to four other large cetaceans Using a large database, they found different brain sizes among 5 different taxa The dolphins in their dataset ranged in weight from 40 to 6,750 kg, and brain masses ranged from 0.4 to 9.3 kg. Dolphins range in length from 1.3 to 7.6 meters In a combined dataset of four other groups of cetaceans, body weight varied from 20 to 120,000 kg, brain weight from about 0.2 to 9.2 kg, and body length from 1.21 to 26.8 m. Not all cetaceans have large brains relative to their body size Some human-sized dolphins have human-sized brains On the other hand, the brain of some cetaceans is one-sixth the width It was found that brain size depends on body weight from the Porphinidae, the Porpoicidae and Monodontocetidae groups, to another cetacean, the Cetacea and finally the Cetidae. A similar trend was observed when we compared brain weight by body length, except for the Delphinidae and Delphinidae-Delphinidae groups, which did not differ. Ballenidae had the smallest brain and the least cerebral cortical surface. The parts of the brain are also different Dolphins also have a large cerebellum for their body weight and body length Cortical surface up to the size of the brain, excluding cetaceans The data showed that cetaceans had smaller brains than other cetaceans measured

A network of large vessels in the cranial parietal region helps maintain brain heat, and the volume of this non-brain tissue increases with body weight and height, accounting for 8% to 65% of the intracranial volume.

Because the intracranial vascular network and other appendages (such as the tentorium) vary greatly among species, brain size measured in some extinct cetacean brain models may be exaggerated. Body length reconstructions of intracranial appendages can be used to better estimate endocasts or intracranial volumes of living species or brains from extinct cetaceans.

Here’s a brief understanding of the neuroscience of how dolphins, especially bottlenose dolphins, display such adaptive and cognitive skills.
