Flow changes in visceral blood vessels of the chub (Leuciscus cephalus) during behavioral arousal

Habituation of fright and arousal responses in the teleosts Carassius auratus and Rutilus rutilus..

“…Similarly Peeke (1969) found aggressive responses of sticklebacks waned more rapidly than did orientations. This gives a picture of habituation which is consistent with the view that fright and arousal are responses differing in degree rather than type (Gastaut & Roger, 1960;Laming & Savage, 1978, 1980. Goldfish swimming free in an aquarium take from 18 to 60 presentations of a plunger stimulus before fright and arousal responses habituate.…”

“…different types of response, whereas others (Gastaut & Roger, 1960) maintain that the responses differ only in the degree of central nervous system activation they entail. Recent work on fish suggests the apparently contrary cardiac responses of arousal and fright may be accounted for by the same physiological mechanism (Laming 1981b;Laming & Savage, 1978). Fright responses in fish are typically made to intense stimuli, especially those involving pressure changes (Laming & Savage, 1980).…”

“…Physiological changes are associated with the two behavioral responses. In arousal, there is a reduction in heart rate, ventilatory rate, and amplitude (Laming & Savage, 1980) and flow in visceral blood vessels (Laming & Savage, 1978). There is an increase in the 16-24-Hz activity of the electroencephalograph (EEG; Laming, 1980).…”

Behavioural, physiological and morphological adaptations of the shanny (Blennius pholis) to the intertidal habitat

“…On reimmersion a transient bradycardia occurs which is similar to the teleost arousal bradycardia, shown by Laming & Savage (1978) to be associated with visceral blood flow changes which may channel the newly available oxygen to vital systems. The transient reimmersion bradycardia is followed by a period when both heart and ventilation rates rise above normal levels.…”

Localization of telencephalic regions concerned with habituation of cardiac and ventilatory responses associated with arousal in the goldfish (Carassius auratus).

“…In teleost fish, the dorsal fin is erected, there are changes in pectoral fin movements, and the eyes move (Laming & Savage, 1980;Russell, 1967;Savage, 1971). Laming and Savage (1978), using goldfish, found concomitant cardiac and ventilatory decelerations and a decrease in flow in visceral blood vessels. An increase in the amplitude of the 16-24-Hz electroenccphalographic activity has also been found (Laming, 1980;Laming & Savage, 1981;Schade & Weiler, 1959).…”
