متن کاملLatent inhibition experiments with goldfish (Carassius auratus).
Evidence of latent inhibition was sought in a series of experiments with goldfish. In Experiment 1, goldfish were given nonreinforced preexposure to a color that subsequently predicted shock in an activity conditioning situation; their performance did not differ from that of control animals preexposed to a markedly different color. In Experiment 2, a group of goldfish given nonreinforced preexp...
متن کاملPhysiological consequences of gill remodeling in goldfish (Carassius auratus) during exposure to long-term hypoxia.
Goldfish (Carassius auratus) acclimated to 7 degrees C and exposed to hypoxia ( approximately 10 mmHg) for 7 days exhibited a pronounced remodeling of the gill consisting of the removal of an interlamellar cell mass (ILCM). Subsequent experiments were designed to assess the impact of gill remodeling and the associated increase in functional lamellar surface area on the distribution of branchial...
متن کاملThe control of breathing in goldfish (Carassius auratus) experiencing thermally induced gill remodelling.
At temperatures below 15°C the gill lamellae of goldfish (Carassius auratus) are largely covered by an interlamellar cell mass (ILCM) which decreases the functional surface area of the gill. The presence of the ILCM in goldfish acclimated to cold water conceivably could lead to a covering of the neuroepithelial cells (NECs), which are believed to be important for sensing ambient O₂ and CO₂ leve...
متن کاملThe consequences of reversible gill remodelling on ammonia excretion in goldfish (Carassius auratus).
Goldfish acclimated to cold water (e.g. 7°C) experience a marked reduction in functional lamellar surface area owing to the proliferation of an interlamellar cell mass (ILCM), a phenomenon termed gill remodelling. The goal of the present study was to assess the consequences of the reduced functional surface area on the capacity of goldfish to excrete ammonia. Despite the expected impact of ambi...
