Creative people wired to see the world differently

Creative people are wired to see the world differently than others, the scientists say.

Researchers studying brain scans of people who were asked to come up with inventive uses for everyday objects found a specific pattern of connectivity that correlated with the most creative responses.

They were able to use that pattern to predict how creative other people’s responses would be based on their connections in this network.

“What this shows is that the creative brain is wired differently,” said Roger Beaty, a post-doctoral fellow at Harvard University in the US.

“People who are more creative can simultaneously engage brain networks that do not typically work together,” said the author of the study.

“We also used predictive modelling to show we could predict, with some degree of accuracy, how creative people’s ideas were (based on brain scans) that had already been published,” he said.

The team reanalysed brain data from previous studies and found that, by simply measuring the strength of connections in these peoples’ brain networks, they could estimate how original their ideas would be.
While the data showed that regions across the brain were involved in creative thought, the researcher  said the evidence pointed to three sub-networks - the default mode network, the salience network and the executive control network - that appear to play key roles in creative thought.

The default mode network, he said, is involved in memory and mental simulation, so the theory is that it plays an important role in processes like mind-wandering, imagination, and spontaneous thinking.

“In terms of creativity, we think that is important for brainstorming,” the researcher said.

“But you are not always going to stumble onto the most creative idea that way, because you might be drawn to something unoriginal from memory, so that is when these other networks come online,” he said.

The salience network detects important information, both in the environment and internally.

When it comes to creativity, researchers believe it may be responsible for sorting through the ideas that emerge from the default mode network.

The executive control network works to help people keep their focus on useful ideas while discarding those that are not working, the researcher said.

Ringing in ears cause brain to stay more at attention

Tinnitus, a chronic ringing or buzzing in the ears, is associated with changes in certain networks in the brain, and those changes cause the brain to stay more at attention and less at rest, a research has found.

While the buzzing in the ears condition has eluded medical treatment and scientific understanding, the finding provides patients with validation of their experiences and hope for future treatment options.

The results published  also suggest that if you have bothersome tinnitus, you may have concentration issues as their attention may be engaged more with their tinnitus than necessary, and that may lessen their attention to other things.

"Tinnitus is invisible. It cannot be measured by any device we have, the way we can measure diabetes or hypertension," said study leader.
 
"So you can have this constant sound in your head, but nobody else can hear it and they may not believe you. They may think it's all in your imagination. Medically, we can only manage some symptoms, not cure it, because we don't understand what's causing it," researcher said.

One factor that has complicated tinnitus research is the variability in the patient population. Lot of variables such as duration, cause, severity, concurrent hearing loss, age, type of sound, which ear and more led to inconsistent study results.

"We have been so swamped by variability that finding anything that is consistent, that gives us one objective metric for tinnitus, is very exciting," said the researcher.

Using functional MRI to look for patterns across brain function and structure, the study found that tinnitus was in the hearers' heads -- in a region of the brain called the precuneus.

The precuneus is connected to two inversely related networks in the brain -- the dorsal attention network, which is active when something holds a person's attention, and the default mode network, the "background" functions of the brain when the person is at rest and not thinking of anything in particular.

The researchers found that in patients with chronic tinnitus the precuneus was more connected to the dorsal attention network and less connected to the default mode network.

Additionally, as severity of the tinnitus increased, so did the observed effects on the neural networks.
"For patients, this is validating. Here is something related to tinnitus which is objective and invariant," researcher said.

"It also implies that tinnitus patients are not truly at rest even when resting. This could explain why many report being tired more often," researcher added.
