Trial summary

Creativity is a complex neuro-psycho-philosophical phenomenon that is difficult to define. Neurocognitive models of creativity suggest that creativity is associated with the activity of a distributed, bilateral fronto-temporal and parietal network. Read more about this study

About this study

Creativity is a complex neuro-psycho-philosophical phenomenon that is difficult to define. Neurocognitive models of creativity suggest that creativity is associated with the activity of a distributed, bilateral fronto-temporal and parietal network. Therefore, a modulation of frontal activity is necessary to allow a certain degree of "controlled disinhibition", which seems to be necessary for creative thinking. In addition, a modulation of the lower parietal lobe (IPL) might allow targeting the brain regions responsible for idea generation.

This project will investigate the application of transcranial magnetic stimulation (TMS) with the intent of modulating creativity performance of healthy subjects. Resting state electroencephalography (EEG) that will be acquired pre- and post-TMS and participants' creative performance will be measured.

Perspectives include a better understanding of the differences between high- and low-creativity groups, as measured by a creativity test battery, in their response to TMS. Additional perspectives are whether there are differences in creativity performance depending on the stimulation location.

Being tested
Transcranial Magnetic Stimulation (TMS) over the left inferior frontal gyrus (IFG), Transcranial Magnetic Stimulation (TMS) over the left inferior parietal lobule (IPL)

    Measured: 2.5 hours

Secondary outcomes (1)
  1. Change in creativity performance prior- and post-TMS depending on stimulation location

    Change in creativity performance (as expressed by a summary score of single tests from a creativity test battery) prior- and post-TMS depending on the stimulation location (left IFG versus left IPL)

    Measured: 2.5 hours
