What does the radial arm maze test?
The Radial Arm Maze (RAM) was designed by Olton and Samuelson (1976) to measure spatial learning and memory in rats. It is an apparatus consisting of eight horizontal equidistantly spaced arms (usually 57 × 11 cm) radiating from a small circular central platform (30 cm in diameter) elevated (70 cm) off the floor.
How do you test spatial memory in mice?
The T-maze is a simple behavioral paradigm used to assess spatial memory. It consists of a capital T-shape design with a stem length of 35 cm and an arm length of 28 cm for mice (rats: 50 cm and 40 cm, respectively). There is a single choice point with only two alternatives.
What does the Morris water maze test?
The Morris water maze (MWM) is a test of spatial learning for rodents that relies on distal cues to navigate from start locations around the perimeter of an open swimming arena to locate a submerged escape platform.
Which is true about a typical radial arm maze experiment?
Which is TRUE about a typical radial-arm maze experiment? In a typical radial-arm maze experiment, food is continually available in one arm so the most efficient strategy for obtaining food is therefore to learn where that arm is.
What is radial arm water maze?
The radial arm water maze (RAWM) contains six swim paths (arms) extending out of an open central area, with an escape platform located at the end of one arm (the goal arm). The goal arm location remains constant for a given mouse.
Are mice good at mazes?
3.1. 5. Summary. Together, these data show that mice can hold a short-term working-memory representation of reward locations on the hexagon and radiolarian mazes, and that their ability to do so increases with experience of the task.
What is the function of Morris water maze?
The Morris water maze is widely used to study spatial memory and learning. Animals are placed in a pool of water that is colored opaque with powdered non-fat milk or non-toxic tempera paint, where they must swim to a hidden escape platform.
What is typical rat behavior in a radial arm maze quizlet?
In a radial-arm maze, rats typically: move from one arm to the next in an orderly sequence. have no clear order to their choices of arms, and make many repeat visits to the same arms.
