WebThe radial maze is made of white lusterless Perspex (each arm, 50 cm long × 10 cm wide × 40 cm tall), placed in a dimly lit room (50 lx), with room temperature maintained at 23 ± 1 C°. The maze itself has no landmarks; the only landmarks are outside the radial maze on the surrounding walls.

WebThe radial arm maze was designed by Olton and Samuelson in 1976 to measure spatial learning and memory in rats. [1] The original apparatus consists of eight equidistantly spaced arms, each about 4 feet long, and all radiating from a small circular central platform (later versions have used as few as three [2] and as many as 48 arms [3] ).
WebRadial arm maze Radial arm maze is made of Plexiglass; consist of eight equally spaced arms radiating from an octagonal central platform. Each arm was having a length of 56.2cm, width of 7.9 cm and height of 10 cm. The entire maze is elevated 80 m above the floor for easy locating of spatial cues by rats. Nutmeg extract WebEach rat was returned to a transport cage for 30 min before being transported to the radial arm maze for the probe test. On day 13, all rats completed another trial block of radial arm maze testing, and on day 14, rats received a second intracranial infusion of muscimol or saline followed by a trial block in the radial arm maze using the same ...
WebRats pretrained in a radial arm maze performed better in a water maze than non-pretrained rats. No difference between groups was found in a non-spatial water maze task. On the other hand, when pretrained in a water maze, rats performed only marginally better in a radial arm maze compared to non-pretrained animals. WebThe radial arm maze or Olton spatial maze consists of an central area with eight arms extending from it. Exploratory behavior is measured by the total number of arm entries and the number of different arm entries.
WebIn a radial-arm maze, rats typically a. move from one arm to the next in an orderly sequence b. have no clear order to their choices of arms, and make many repeat visits to the same …
WebApr 22, 2013 · Using radial arm maze procedures [17], rats quickly learn to visit each arm only once in a session to retrieve a food reward. Accurate performance is thereby dependent on both memory for previously visited arms and a natural tendency not to revisit arms within a trial, referred to as “win-shift” strategy [18]. how are morals and ethics differenceWebThe radial arm maze is optimized for video tracking and is ideally combined with EthoVision XT. EthoVision XT detects and tracks the center point, nose point, and tail base of mice and rats. This allows for the accurate measurement of an animal’s relative position. how many meters squared in an acreWebThe Radial Arm Maze (RAM) was designed by Olton and Samuelson (1976) to measure spatial learning and memory in rats.
