Problem solved – just keep an ‘open mind’ …

30.01.2008
Ever wondered what goes on in your brain when you are trying to solve a problem? Researchers have found that keeping an ‘open mind’ is the key to being able to solve problems.

Joydeep Bhattacharya, from the Department of Psychology at Goldsmiths, University of London and his graduate student Simone Sandkühler from the University of Vienna, ran a study to find out what changes go on in the brain when it is trying to solve a problem.

The study, published in the Journal PLoS ONE this month, used electroencephalography (EEG) to monitor the brains of volunteers whilst giving them verbal problems to solve. Watching the changes in the brain as the volunteers solved the problems, they particularly wanted to see if the changes were sudden or gradual.

If a volunteer wasn’t able to solve a problem and had hit upon, what researchers call, a ‘mental impasse’ (ie mental block), they could ask for a clue to help them find the answer. The study found that mental impasse was associated with strong gamma rhythms, a brain wave often linked to focussed attention. The strength of gamma rhythms at the time of clue presentation also predicted whether the clue would lead to a correct solution or not: higher the gamma, less likely the solution. Interestingly the researchers found that it was the alpha rhythm, which is usually linked to less-attentive yet spontaneously relaxed brain-state, facilitates thinking that leads to a correct solution.

Dr. Bhattacharya said; “If there is an excessive attention it somehow creates a mental fixation, and the brain is in a less receptive condition. Our findings suggest that it is actually better to tackle problems with an open mind as volunteers who had a high level of alpha brain rhythms, rather than gamma, were much more likely to utilize the clue successfully in order to produce the solution.”

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
