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:
“Totalitarianism is never content to rule by external means, namely, through the state and a machinery of violence; thanks to its peculiar ideology and the role assigned to it in this apparatus of coercion, totalitarianism has discovered a means of dominating and terrorizing human beings from within.”
—Hannah Arendt (1906–1975)
“One’s condition on marijuana is always existential. One can feel the importance of each moment and how it is changing one. One feels one’s being, one becomes aware of the enormous apparatus of nothingness—the hum of a hi-fi set, the emptiness of a pointless interruption, one becomes aware of the war between each of us, how the nothingness in each of us seeks to attack the being of others, how our being in turn is attacked by the nothingness in others.”
—Norman Mailer (b. 1923)
“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)
