Researchers studying the brain have long been interested in its neural oscillations, the rhythmic electrical activity that plays an important role in the transmission of information within the brain's neural circuits.

The main problem is that it is extremely difficult to measure electrical activity deep inside the brain of a living person, and differences between the brains of living people and those of the animals and cadavers that previous studies have used are significant.

By testing cycling time to task failure (TTF) in a group of 12 active participants in a placebo controlled study, Dr Mauger discovered that stimulating the brain by passing a mild electrical current (transcranial direct current stimulation or tDCS) over the scalp to stimulate it increased the activity of the area associated with muscle contraction.

Such studies could guide still - experimental therapies such as transcranial magnetic stimulation, which aims to suppress or boost brain activity in targeted areas through electrical currents.
