2022年2月12日 · I had to re-read the Richter paper a couple of times to digest it, and from my understanding, the differences in swimming time was in the same (first) experiment. The tweak to the experiment was where, instead of using domesticated rats, they used hybrid rats ("crosses between domesticated and wild rats"). References. Richter, C. P. (1957).

Therefore, apart from the fact that the article was discussing data on a domesticated albino strain of the Norway rat, all the experiments mentioned used brown rats. There were no black rats, mole rats, or any other kinds of rat used. References. Calhoun, J.B. (1962). Population density and social pathology. Scientific American, 206, 139—48.

2013年8月15日 · Here we evaluated ghrelin response to stress in rats after ovariectomy and during estradiol benzoate (EB) therapy and compared results of males and females, to know whether ghrelin is involved in disordered eating behaviors in response to stress, and for understanding differences between males and females in food intake and weight gain ...

2024年4月3日 · Rats tend to explore spaces rather than stay still, they seek open spaces over dead ends, and prefer novel areas over repeated visits. The availability of space to explore, open corridors vs blind alleys, and unexplored sections of the maze constitute the stimuli, to which the rats respond by choosing which parts of the maze to traverse.

Suppose you make a rat run through a maze to find it's food. Every day, you put the rat into the same maze. The first few times this rat has to run the maze, it will probably take a little while to

The brain size/intelligence correlation is also found in non-human animals, both within a species (e.g. rats) and between different species (e.g. species of birds, species of primates). Brain size is also environmentally sensitive: for instance, rats raised in complex environments have thicker cortices and larger brains than rats reared in ...

2021年11月10日 · If you make Cheetos available to any other group of rats they will also be Cheeto-eating rats for as long as those are available. Galef Jr, B. G., & Wigmore, S. W. (1983). Transfer of information concerning distant foods: a laboratory investigation of the ‘information-centre’hypothesis.

2024年12月11日 · Solving T-shaped maze (probability learning): differences between rats and humans 3 Is the weight of neural inputs in the human brain as central as it is for neurons in an artifical neural network?

Over a number of years, the ethologist John B. Calhoun conducted over-population experiments on Norway rats (in 1958–1962) and mice (in 1968–1972). His studies describe the collapse in behavior which resulted from overcrowding.
