Apparatus
The Oasis maze is a circular, acrylic board (1.8 m in diameter) that is painted flat white and raised 76 cm from the floor by a table with a lazy Susan attached, allowing the board to be freely rotated about its central axis. The surface of the board contains 426 evenly spaced wells (2.5 cm in diameter, 1.3 cm in depth) in which small amounts of water (0.3 ml) can be hidden. Water is used as a reward because, unlike food rewards, rats cannot locate the water using olfactory cues.

Famous quotes containing the word apparatus:
“... But all the feelings that evoke in us the joy or the misfortune of a real person are only produced in us through the intermediary of an image of that joy or that misfortune; the ingeniousness of the first novelist was in understanding that, in the apparatus of our emotions, since the image is the only essential element, the simplification which consists of purely and simply suppressing the factual characters is a definitive improvement.”
—Marcel Proust (1871–1922)
“It is part of the nature of consciousness, of how the mental apparatus works, that free reason is only a very occasional function of people’s “thinking” and that much of the process is made of reactions as standardized as those of the keys on a typewriter.”
—John Dos Passos (1896–1970)
“Opinions are to the vast apparatus of social existence what oil is to machines: one does not go up to a turbine and pour machine oil over it; one applies a little to hidden spindles and joints that one has to know.”
—Walter Benjamin (1892–1940)
