Central nervous system plasticity related to motor learning, strength training and immobilization

During the recent years it has become evident that the properties of the central nervous system are highly plastic. When we learn or practice new motor skills, behavioral changes are reflected by changes within the central nervous system. This plastic remodelling of the nervous system is can be both functional and structural and it is continously ongoing. It remains however largely unclear when, where and how neuroplasticity occurs as a consequence of learning, training or physical inactivity and how neroplasticity more specifically relates to behavior.

The purpose of the project is to gain understanding of how motor learning, training and immobilization affect the properties of the central nervous system and vice versa. The experiments involve different noninvasive electrophysiological and neuroimaging techniques like functional magnetic resonance imaging (fMRI), EEG, transcranial magnetic stimulation of the motor cortex (TMS), EMG and tests of spinal reflex mechanisms. In addition, the experiments also involve more functional behavioral tests of balance, strength, accuracy, gait etc. So far, the experiments revealed changes at both spinal and supraspinal levels as a consequence of both training and physical inactivity.
