This workpackage investigated the neural underpinnings of intentional action control. Important questions concern how our intentions motivate whether we act, when we act and what kind of actions we perform.

Action control is a high-dimensional process offering a multitude of possible choices. Workpackage 5 investigated different aspects of action selection and inhibition by tracing dynamic changes in neural activity and connectivity strength in networks involved in conflict resolution and action control.

In workpackage 4, we examined and compared activity patterns and dynamic changes in connectivity strength in brain systems that are involved in learning and prediction.

This workpackage used non-invasive Transcranial Brain Stimulation (NTBS) techniques such as transcranial magnetic stimulation (TMS) which can directly interact with the brains ongoing electrical activity without causing significant discomfort.

EEG and fMRI can capture functional integration within large-scale brain systems. Work package 2 employed two different methods to investigate functional and effective connectivity in brain networks. 

This workpackage aimed at optimizing existing tractography methods to fully exploit the full potential of diffusion MRI. Measures of structural connectivity pathways in the brain can then be used to discover their role in action control.

Mapping of brain and behavioural changes throughout life

The national 7-tesla MRI scanner was installed after generous donations from the John and Birthe Meyer Foundation and the Danish Agency for Science, Technology and Innovation. This scanner is the most powerful and the only one of its kind in Denmark, and has been officially in use since 2016. The scanner is dedicated for research only.

DRCMR has a strong focus on non-invasive transcranial brain stimulation (NTBS) to study and shape human brain function.
