    Differential control of cardiac functions by the brain
    (Blackwell Publishing, 2006-12-01) Salo, Lauren M.; Campos, Ruy R.; McAllen, Robin M.; Univ Melbourne; Universidade Federal de São Paulo (UNIFESP)
    1. the idea is introduced that cardiac rate, contractility or atrioventricular (A-V) conduction spread may be controlled independently by the brain. Limited data from reflex studies are cited to support this view.2. Evidence is presented that individual autonomic post- and preganglionic neurons have quite specific actions on the heart. Premotor and other central neurons can have preferential actions on heart rate, contractility or A-V conduction.3. the functional implications of selective cardiac control are discussed.
