Tectotectal connectivity in goldfish
The Journal of Comparative Neurology, 1999The vertebrate optic tectum is a functionally coupled bilateral structure which plays a major role in the generation of motor commands for orienting responses. However, the characteristics of the tectotectal connectivity are unknown in fish, and have been reported only to a limited extent in other vertebrates.

ACM SIGGRAPH 2010 Computer Animation Festival, 2010
In the Goldfish crackers animated commercial series, the main character, Gilbert, is gone. The unfortunate cracker character was sucked up by a vacuum cleaner. But with the help of friends, Gilbert embarks on a new adventure and finds himself "In the Dark," but not alone.

Reward and Learning in the Goldfish
Science, 1967An experiment with goldfish showed the effects of change in amount of reward that are predicted from reinforcement theory. The performance of animals shifted from small to large reward improved gradually to the level of unshifted large-reward controls, while the performance of animals shifted from large to small reward remained at the large-reward ...

Temporal discrimination in the goldfish
The Journal of the Acoustical Society of America, 1982The capacities of the goldfish to detect changes in sound burst repetition rate were studied using classical respiratory conditioning. In experiment I, the just detectable amount of an instantaneous random jitter of burst period was measured as a function of mean period.

Colour discrimination in goldfish
Animal Behaviour, 1966Summary Goldfish were trained to discriminate between blue, green, and red painted panels, which varied greatly in brightness. The stimuli were chosen in such a way that the discriminations could not be solved in terms of brightness. All the discriminations were easily learnt by the fish, in spite of the large brightness differences.

Degradation of DDT by goldfish
Bulletin of Environmental Contamination and Toxicology, 1971Goldfish were fed DDT for three weeks, then exposed to phenobarbital solution for one week to study the possibility of microsomal enzyme induction and therefore possibly enhanced insecticide excretion. Analysis of DDT, DDE and DDD were made at intervals up to six weeks. Forty percent of the DDT fed was incorporated during the feeding.

Puromycin and Retention in the Goldfish
Science, 1967A first experiment compared the behavior of goldfish injected with puromycin immediately after each of a weekly series of brief discriminative training sessions in the shuttlebox to that of appropriate controls. Discrimination was not prevented, nor was escape from shock impaired, but probability of response to the conditioned stimuli, both positive ...

Perception of pitch by goldfish
Hearing Research, 2005Classical conditioning and stimulus generalization methods have revealed much about the sense of hearing in non-human animals, and are now used here to investigate how goldfish perceive a variety of complex sounds, including multi-harmonic complexes and rippled noise (RN).

Analytic listening by the goldfish
Hearing Research, 1992A stimulus generalization paradigm was used with classical respiratory conditioning to study analytic listening in the goldfish. Animals were first conditioned to suppress respiration upon the presentation of a long-duration complex sound comprised of two sinusoidal components, 166 and 724 Hz. Conditioned animals were then presented with a set of eight

Histogenesis of the goldfish retina
Journal of Comparative Neurology, 1980AbstractThe order of production of retinal cells was studied in embryos of the goldfish, Carassius auratus using 3H‐thymidine autoradiography. Cell division ceases first in the neuroepithelium at the fundus of the eye between embryonic stages 19 and 20 and gradually becomes restricted to the retinal margin by stage 24.
