Resumen:
Regulation of physiological activities in animals is crucial for thepreservation of equilibrium. Such activities include the change ofcirculatory parameters in response to different behavioural andphysiological requirements. The sympathetic prevailing situation, withhigh heart rate (HR) and low digestive movements, is termed the ?fight orflight? stage. This stage describes the behaviour of animals that fightagainst or flee from an enemy or danger. The parasympathetic overridingsituation, with a high level of digestive movements and a low HR istermed the ?rest and digest? stage (Cannon 1929, Cannon 1932).The autonomic nervous system (ANS) has presumably originated withthe emergence of vertebrates (Sarnat and Netsky 2002); in fact, a similararchitecture to that seen in mammals can also be traced in fishes(Nieuwenhuys et al. 1998). However, taking into account that ininvertebrates, there is no structural counterpart of vertebrae, an intriguingquestion is how cardiac regulation by any autonomic system is achieved in
