1. New advances in MRI scanning reveal the level of intelligence in the brain.
2. The more that different parts of the brain frequently connect with each other the higher the person’s level of IQ and creatively is.
3. This has the capacity to markedly advance the technology of Artificial Intelligence.
Professor Jianfeng Feng, from the Department of Computer Science at the University of Warwick in the UK, has been measuring human intelligence for the first time ever (1). The research scientists have found that the more variable a brain is, that is, the more the different parts of the brain frequently connect with each other, the higher a person’s IQ and creativity are. They have been undertaking to quantify the brain’s dynamic functions to ascertain how intellect works.
Using resting-state MRI analysis, the research has found that areas associated with learning and development show high levels of neural connections with other parts of the brain over a matter of minutes or even seconds. Areas of the brain that are not associated with intelligence, for instance visual or auditory areas, show small variability or neural connectivity.
This leap of understanding in human intelligence has the capacity to markedly advance the technology of Artificial Intelligence (AI). Currently AI systems do not have the dynamic qualities that the human brain has, enabling growth and learning. If the variability, or the interconnectedness of the human brain could be applied to the construction of artificial neural networks for computers, it would give them the ability to learn and grow and adapt.
This study may also have the capacity to delve deeper into our understanding about mental health. By studying the variable brain patterns of patients with schizophrenia, depression, ADHD. This technology might well help find greater understanding of these psychological conditions.
Professor Feng has commented on this revolutionary process saying, “Human intelligence is a widely and hotly debated topic. Only recently have advanced brain imaging techniques given us the opportunity to gain insights to resolve this and make informed developments in artificial intelligence as well as help establish the basis for understanding and diagnosis of debilitating mental disorders such as schizophrenia and depression.”
Predictive brain scanning may well become a whole new subject of discourse for the ever-evolving field of neuroscience. But until MRI scanning takes over IQ tests completely, there’s nothing wrong with you doing your own MENSA test.
