In predicting intelligence from brain scans, the algorithm is doing something that humans cannot, because even an experienced neuroscientist cannot look at a brain scan and tell how intelligent a person is.
Brains with more connections between two regions known as the frontal and parietal lobes, it turns out, display more fluid intelligence, and the number and strength of these connections is visible from an fMRI scans.
Neural bases of intelligence
As imaging technology has improved, so has the ability for deeper neuro-analysis. MRI studies have found that the volume of gray matter correlates to intelligence, providing evidence for generalizations made regarding brain/head-size and intelligence.
Similarly to brain volume, global grey matter volume is positively associated with intelligence. More specifically, higher intelligence has been associated with larger cortical grey matter in the prefrontal and posterior temporal cortex in adults.
A new study shows that looking at brain activity, detected through fMRI scans, is a fairly accurate way to measure intelligence.
A few interesting research studies show that people who have an IQ above an average level use different regions of the brain while solving tasks than people with average IQ scores.
The high IQ level tends to be more balanced with smaller asymmetry value for alpha and beta waves. A high IQ level is characterized by a right dominant alpha activity. In contrast, beta activity is left dominant. Meanwhile, medium and low IQ levels indicate unbalanced brain activity with greater asymmetry values.
Signs of Genius in Adults. The signs of high intellectual power in adults are similar to those in children. They include quick learning, interest in unique topics, and the ability to process information fast, among others.
Research shows that the signs of intelligence are usually good memory and thinking ability, good attitude and hard-working nature, general and tacit knowledge, language proficiency and reasoning, decision-making, trust, creativity, achievements, good intuition, and problem-solving.
Geniuses have a denser concentration of mini-columns than the rest of the population – it seems that they simply pack more in. Mini-columns are sometimes described as the brain's 'microprocessors', powering the thought process of the brain. Research shows that geniuses have fewer dopamine receptors in the thalamus.
Researchers have previously shown that a person's IQ is highly influenced by genetic factors, and have even identified certain genes that play a role. They've also shown that performance in school has genetic factors. But it's been unclear whether the same genes that influence IQ also influence grades and test scores.
People with a higher-than-average intelligence level have brains that are “wired” in a different way, researchers say. A new study suggests that intelligence is linked with increased connectivity between some regions, and reduced interaction between others.
Summary: Using a large dataset and controlling for a variety of factors, including sex, age, height, socioeconomic status, and genetic ancestry, scientists found that people with larger brains rated higher on measures of intelligence and educational attainment.
Brain size has a surprisingly small impact on intelligence and behavior. Key Points: Having an unusually large brain doesn't necessarily make someone a genius, and large-scale research suggests only a slight and tenuous relationship between brain size and intelligence.
A team of American neuroscientists have discovered that your intelligence can be predicted fairly accurately with an fMRI brain scan. The study, published in high-profile journal Nature Neuroscience found that individuals' "fluid intelligence" can be found out through the analysis of connections within the brain.
For highly intelligent people, whilst they are most interested in finding solutions for real-life problems, they also enjoy pondering deep philosophical ideas and abstract concepts. From a young age, they have an insatiable curiosity about life; They thrive on learning.
Some psychologists believe that the ability to listen to another person, to empathize with, and to understand their point of view is one of the highest forms of intelligent behavior.
Recap: 4 Reasons highly intelligent people fail
They are born into bad circumstances, poverty, a toxic family, a lack of resources and opportunities. They suffer from mental illness, which creates myriad other barriers to career advancement and better paychecks. They lack people skills or are arrogant.
For example, raw speed in processing information appears to peak around age 18 or 19, then immediately starts to decline. Meanwhile, short-term memory continues to improve until around age 25, when it levels off and then begins to drop around age 35.
The cerebello-parietal component and the frontal component were significantly associated with intelligence. The parietal and frontal regions were each distinctively associated with intelligence by maintaining structural networks with the cerebellum and the temporal region, respectively.
Your brain begins to emit alpha waves instead of beta, which is what you emit when you're fully awake. To enter the alpha state of mind, start by getting relaxed, and then move on to different techniques that can get you in the alpha state of mind, including deep breathing, countdowns, and visualizations.
