Document Summary

Any given behavior is the product of a myriad of complex neurophysiological and biochemical interactions involving the whole brain: there is no one to one relationship between a specific behavior and a specific neuroanatomical structure. It may occur after a stroke or in association with damage to the parietal lobe. A lack of understanding of the rules for calculation or arithmetic (acalculia or dyscalculia). An inability to distinguish right from left. An inability to identify fingers (finger agnosia): administering many tests is important to come to more reliable conclusions. Cranial nuclei for mouth and throat structures: reticular formation. Damage to lateral medullary structures can result in sensory deficits. Spans from the upper spinal cord to the diencephalon. Many interconnected nerve centers important for posture, smooth muscle movement and tone. Injury results in drowsiness or coma: the pons. Contains major pathways for fibers running between cerebral cortex and cerebellum. Pons and cerebellum = postural and kinesthetic (muscle movement) sense.
