TL;DR: An apparatus was developed to expose goldfish to controlled, localised heat stimulation and the hypothesis that goldfish perceive heat as aversive was tested, and all 16 fish responded to the heat with an escape response, with a mean baseline of 38 8C.

TL;DR: Trace classical conditioning can be used for inducing anticipatory behaviour in ad libitum fed laying hens freely moving in the home pen environment based on trace conditioning and demonstrates that the results demonstrated that the EX hens responded to the CS with an increased level of anticipating behaviour compared to the CO hens.

TL;DR: The hypothesis that rearing in a barren cage environment relative to a complex aviary environment causes long-lasting deficits in the ability to perform spatial tasks is supported.

TL;DR: The hypothesis that laying hens reared in a complex aviary system with exposure to mild intermittent stressors would be less fearful, less sensitive to stress, and would use elevated areas of the pen more often as adults than hens raised in a barren cage environment is supported.

TL;DR: A low dose of LPS can induce changes in brain cytokine levels and neurotransmitter levels that persist after inflammatory and stress markers in the periphery have returned to baseline levels.
