The full study, " Serotonin signaling in the brain of adult female mice is required for sexual preference" is published in the journal Proceedings of the National Academy of Sciences. John Calhoun’s colony was a mouse utopiaa giant pen with everything a mouse could ever desire: plenty of food and water, a perfect climate, and reams of paper to make cozy nests. Understanding the biochemistry of human sexuality and the ethical discussions that will come with investigating and manipulating genes that potentially influence sexual orientation still seem a long but interesting way off. Explore scientist John Calhoun’s mouse utopia and what it can tell us about the ways we impose lessons for society onto lab experiments. For example, in human society today, we note that socialism / progressivism teaches children that. Every aspect of Universe 25, as this particular model was called, was designed to cater for the well-being. ![]() Use of the word mutant could seem unfortunate, but it's just a trade term used in every article about genetics ever, describing changes relative to a given starting point.įor now this is just an interesting experiment that tells us serotonin plays a role in sexual orientation. Many scientists have dismissed any link between Calhoun's 'mouse utopia' experiments and human society, but in the years since these conclusions were drawn, human society has come to strikingly resemble the self-annihilation tendencies of the mice. ![]() In late October, the first litter of mouse pups was born. Zhang and company concluded that not having certain neurons that release serotonin "cause a reversal of sexual preference, revealing a role for in regulating sexual preference." Even Universe 25the biggest, best mousetopia of all, built after a quarter century of researchfailed to break this pattern. In Universe 25, a population of mice would grow within a 2.7-square-meter. Strange and thought provoking episode today In the 1940s, 50s, and early 60s, animal behavior researcher John B Calhoun ran a number of experiments on roden. IMPLICATIONS: "Mutant females lacking serotonergic neurons" showed preferences for females over males. Expanding on his earlier studies, Calhoun devised his ultimate research experiment. Aberrations included the following: females abandoning their young males no longer defending their territory and both sexes becoming more violent and aggressive. ![]() Proceedings of the National Academy of Sciences The turning point in this mouse utopia, Calhoun observed, occurred on Day 315 when the first signs appeared of a breakdown in social norms and structure.
