tDCS Technology Offers Many Benefits
Sharpened Focus and Attention
A number of studies have demonstrated the ability of these machines to improve focus and attention. Much in the same way caffeine works; tDCS can enhance the user’s ability to stay focused on a task which leads to higher productivity and overall better cognitive function. In fact, some studies have directly compared the effects of caffeine and tDCS on performance and suggested that tDCS may actually outperform caffeine. This improved performance is well highlighted in RadioLab’s podcast “-Volt Nirvana” found here: http://bit.ly/ZqAFDy
The ability of tDCS to improve elements of memory is another area of study which has been widely assessed. Studies have indicated that the application of a single session of tDCS can improve working memory as measured by cognitive tasks. Working memory is the phase of memory which lies between short term and long term memory and is critical for good cognitive function. Interestingly it is this memory which typically begins to decline with age and is the target for improvement in brain training games like Lumosity.
Greater Problem Solving
In addition to proving memory and focus, tDCS has been shown to improve aspects of problem solving. One study found that during a difficult cognitive task the defining feature of those who had solved the problem versus those who had not was whether or not they had received stimulation. Additional studies have mirrored this same conclusion. This potential for better problem solving has far reaching implications in the real world and everyday life.
