The cerebral cortex is responsible for integrating higher mental functioning and conscious thought, sensations and general movements. Central Nervous System. The portion of the nervous system that consists of the brain and spinal cord. It is primarily involved in voluntary movement and thought processes. In some cases, a contrast medium, which is opaque on x-rays, may be injected intravenously to produce enhanced images of certain tissues, organs or blood vessels.

Such medications stimulate dopamine receptors and produce dopamine-like effects. Partial loss of the ability to coordinate and perform certain purposeful movements and gestures in the absence of motor or sensory impairments. An EEG reveals characteristic brain wave patterns that may assist in the diagnosis of particular neurologic conditions, such as seizures, impaired consciousness and brain lesions or tumors.

The condition may be chronic and cause weakness of the lower esophageal sphincter, the ring-shaped muscle located at the junction of the esophagus and stomach.
