Home Cage Testing of Decision-Making
نویسندگان
چکیده
Testing rodents in their home cages has become increasingly popular. A new low-cost computer-controlled operant panel was designed, which can be placed inside the home cage. A pilot study was carried out, using a decisionmaking protocol, which was adapted from the original maze rodent Iowa Gambling Task (r-IGT). Male adult rats were tested in their home cages, containing the operant panel provided with nose-poking holes. Nose-poking was associated with rewards of different value and probability. A tryptophan-free diet was fed to investigate the effect of lowering central serotonin concentration on performance in the r-IGT. The data suggested that control rats behave in a way similar to rats tested in the original r-IGT; that is, they tend to choose the option with the best long-term payoff more often as the test progresses. Tryptophan depleted rats showed a weaker improvement across trials than controls.

This paper reviews and compares two R packages ``FPV" and ``Fuzzy.p.value".These packages are designed for testing hypotheses in a fuzzy environment using a fuzzy $p$-value based approach.In fact, the packages ``FPV" and ``Fuzzy.p.value" propose some useful functions for testing hypotheses when the data / hypotheses are fuzzy rather than crisp.The proposed methods and function...
متن کاملFighting in the home cage: Agonistic encounters and effects on neurobiological markers within the social decision-making network of house mice (Mus musculus).
Inbred strains of mice, such as C57Bl/6, have become preferred animal models for neurobehavioral studies. A main goal in creating inbred lines is to reduce the effects of individual genetic variation on observed phenotypes. Most studies use only males, and there is increasing evidence that agonistic interactions within the home cage may produce systematic variability in behavior and brain funct...

It is impractical to implement conservation efforts for all species due to complexity of natural systems, large scale of biodiversity issues, and budget limitations. Prioritizing species of conservation importance can alleviate this issue. Multiple interrelated criteria may be used for conservation prioritization of species. Therefore, the accurate evaluation of criteria is a multi-criteria dec...
