A Spinal Functional Magnetic Resonance Imagine (fMRI) Study of Resting-State, Motor Task and Acupoint Stimulation
Summary
The spinal cord is a very important part of the central nervous system. fMRI can be applied to observe functional status of the human spinal cord. Under different conditions, the investigators will see different types of fMRI signals within the spinal cord. In resting state, the investigators might see active/inactive signals, too.

Medical and Biotech [MESH] Definitions
Infarction, Anterior Cerebral Artery
NECROSIS occurring in the ANTERIOR CEREBRAL ARTERY system, including branches such as Heubner's artery. These arteries supply blood to the medial and superior parts of the CEREBRAL HEMISPHERE, Infarction in the anterior cerebral artery usually results in sensory and motor impairment in the lower body.
Middle Cerebral Artery
The largest of the cerebral arteries. It trifurcates into temporal, frontal, and parietal branches supplying blood to most of the parenchyma of these lobes in the CEREBRAL CORTEX. These are the areas involved in motor, sensory, and speech activities.
Cerebral Infarction
The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction).
Feedback, Sensory
A mechanism of communicating one's own sensory system information about a task, movement, skill, etc.
Infarction, Middle Cerebral Artery
NECROSIS occurring in the MIDDLE CEREBRAL ARTERY distribution system which brings blood to the entire lateral aspects of each CEREBRAL HEMISPHERE. Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the infarction.
