Brain Network Dynamics of Local and Global Predictive Processing in Aging

ABSTRACT Cognitive aging is widely associated with a progressive weakening of neural responses associated with predictive brain mechanisms. This view is supported by decades of electrophysiological studies reporting attenuated mismatch responses in older adults. Yet the literature remains inconsistent, suggesting that...

Striatal Dopaminergic Dysfunction Constrains Motor Invigoration in Parkinson’s Disease

Bradykinesia is a cardinal motor feature of Parkinson’s disease and is characterised by a reduced ability to generate movements with normal speed and force. Although nigrostriatal dopamine loss is regarded as the primary cause, direct human evidence linking dopaminergic degeneration to striatal dysfunction and impaired...

Opposing modulation of cortical and corticospinal excitability across movement-related beta stages

Discrete voluntary movement depends on rapid changes in neural excitability across cortical and corticospinal circuits, yet how intrinsic movement-related neural states shape multi-level excitability remains unclear. Here, we combined individualized, state-targeted transcranial magnetic stimulation (TMS) with electroen...
