The gun-powered mouse trap proved inferior to spring-powered mousetraps descending from William C. Hooker's 1894 patent. However, the 1882 patent has continued to draw interest–including efforts to reconstruct a version of it–due to its unconventional design. [ 4 ]
Mouse Trap (originally titled Mouse Trap Game) is a board game first published by Ideal in 1963 for two to four players. The game was one of the first mass-produced, three-dimensional board games. Over the course of the game, players at first cooperate to build a working Rube Goldberg-like mouse trap.
James Henry Atkinson (c. 1849–1942) was a British ironmonger from Leeds, Yorkshire who is best known for his 1899 patent of the Little Nipper mousetrap. [1] He is cited by some as the inventor of the classic spring-loaded mousetrap, [2] [3] but this basic style of mousetrap was patented a few years earlier in the United States by William Chauncey Hooker in 1894.
The house mouse (Mus musculus) has a gestation period of 19 to 21 days. Key events in mouse brain development occur both before and after birth, beginning with peak neurogenesis of the cranial motor nuclei 9 days after conception, up to eye opening which occurs after birth and about 30 days after conception.
"Behavioral sink" is a term invented by ethologist John B. Calhoun to describe a collapse in behavior that can result from overpopulation.The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. [1]
The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...
Image of a guillotine-style mousetrap seller in the mid-19th century. In February 1855, Emerson wrote in his journal, under the heading "Common Fame": If a man has good corn or wood, or boards, or pigs, to sell, or can make better chairs or knives, crucibles or church organs, than anybody else, you will find a broad hard-beaten road to his house, though it be in the woods.
Brain mapping can show how an animal's brain changes throughout its lifetime. As of 2021, scientists mapped and compared the whole brains of eight C. elegans worms across their development on the neuronal level [67] [68] and the complete wiring of a single mammalian muscle from birth to adulthood.
