To regulate the temporal structure of a series of behavioral sequences involving multiple actions, it is essential to monitor the progress of the entire behavioral process. To identify the involvement of three cortical motor areas in monitoring behavioral sequences, we examined neuronal activity while monkeys sequentially performed a series of motor tasks in accordance with a predetermined beha...

Motor imagery is defined as an act wherein individual contemplates a mental action of motor execution without apparent action. Mental practice executed by repetitive can improve performance simultaneous sensory input or overt output. We aimed to investigate cerebral hemodynamics during and self-feeding activity using chopsticks. This study included 21 healthy right-handed volunteers. The task c...

Micrographia is a common symptom in Parkinson's disease, which manifests as either a consistent or progressive reduction in the size of handwriting or both. Neural correlates underlying micrographia remain unclear. We used functional magnetic resonance imaging to investigate micrographia-related neural activity and connectivity modulations. In addition, the effect of attention and dopaminergic ...
