Functional MRI is used to compare the functional neuroanatomy of motor execution and imagery using a task that objectively assesses imagery performance, including the effects of imagery performance and stimulus-dependency on brain activity.

Results indicate that motor performance of not only the hands but also the legs can be enhanced by anodal tDCS, which may be applicable to the neuro-rehabilitation of patients with leg motor disability.
Expectation of Pain Enhances Responses to Nonpainful Somatosensory Stimulation in the Anterior Cingulate Cortex and Parietal Operculum/Posterior Insula: an Event-Related Functional Magnetic Resonance…
It is suggested that ACC and PO/PI are involved in modulation of affective aspect of sensory perception by the uncertain expectation of painful stimulus.
Neural correlates of cross-modal binding

Little is known about how the brain binds together signals from multiple sensory modalities to produce unified percepts of objects and events in the external world. Using event-related functional…
Language Control in the Bilingual Brain
It is revealed that neuronal responses within the left caudate are sensitive to changes in the language or the meaning of words, suggesting that the left Caudate plays a universal role in monitoring and controlling the language in use.

Single Session of Transcranial Direct Current Stimulation Transiently Increases Knee Extensor Force in Patients With Hemiparetic Stroke

- 24 March 2011
Anodal tDCS transiently enhanced knee extensor strength, and the modest increase was specific to the LL, which might augment the rehabilitation of stroke patients when combined with lower extremity strengthening or functional training.
Neural correlates of tic generation in Tourette syndrome: an event-related functional MRI study.
- S. Bohlhalter, A. Goldfine, M. Hallett

- 1 August 2006
The results of this study indicate that paralimbic and sensory association areas are critically implicated in tic generation, similar to movements triggered internally by unpleasant sensations, as has been shown for pain or itching.
Reorganization of the human ipsilesional premotor cortex after stroke.

Results indicate that PMdAH participates as a substrate mediating functional recovery of executive motor function in patients with focal lesions of corticospinal outflow originating in M1 and good motor recovery, consistent with the hypothesis that the dorsal premotor cortex of the affected hemisphere can reorganize to control basic parameters of movement usually assigned to M1 function.
Dynamic Neural Network Reorganization Associated with Second Language Vocabulary Acquisition: A Multimodal Imaging Study

It is proposed that the right hemispheric network can be reorganized into language-related areas through use-dependent plasticity in young adults, reflecting a repertoire of flexible reorganization of the neural substrates responding to linguistic experiences.
