| Abstract: | Neural components important in control of the cardiovascular system during exercise can be divided into central nervous system (CNS) components and peripheral components. CNS components would include the cerebral cortex, cerebellum, medullary region of the brain stem, and the spinal cord. Peripheral components would include the efferent limbs of the autonomic nervous system and afferent fibers carrying information to the CNS. The neural pathways involved in the control of cardiovascular system during exercise and the relationship between the various neural components have been actively pursued in the last few years. Several new studies suggest that information arising from the active muscles and the cardiovascular system itself may be important in the control of the cardiovascular system during exercise. The cerebellum may play a modulating role in the cardiovascular response. The information from the peripheral afferent fibers, the cerebellum, and the cerebral cortex is integrated in the brain to result in overall neural control. Exercise training probably modifies the central integration of information and modifies the cardiovascular response to exercise and other stresses. |
