A new study of the Institute of Cognitive Neuroscience examines the influence of stress on brain activity in left-handed people.

For a study in the field of stress research, researchers at the Ruhr University Bochum are looking for male subjects who are left-handed. The aim is to understand how under stress a network of brain regions becomes active and what role the left and right hemispheres play. To this end, the test subjects undergo an MRI examination at the Leibniz Institute for Human Factors Research in Dortmund. If you would like to participate, please send an e-mail to kognition-mrt@rub.de. Participants will receive an expense allowance of 75 or 150 euros, depending on whether they are needed on one or two days.

All men between 18 and 35 years of age with a body mass index of 18 to 27 are invited to participate. Participants in the study must have a good knowledge of German, be able to hear normally and be mentally and physically healthy. In addition to the MRI examination, subjects complete various tasks on the computer, solve listening tasks, fill out questionnaires and are exposed to an everyday stress situation. In addition, various physical reactions are measured, including the heart rate and, by saliva sample, the stress hormone cortisol.

With a multidisciplinary strategy, brain functions are being researched at the RUB.
