Detailed explanation-1: -The mouse has short hair, a long naked tail, rounded erect ears, protruding eyes, a pointed snout and five toes on each foot. Mice come in a variety of colors.
Detailed explanation-2: -T Maze Spontaneous Alternation is a behavioral test for measuring exploratory behavior in animals, especially rodent models for CNS disorders. This test is based on the willingness of rodents to explore a new environment, i.e. they prefer to visit a new arm of the maze rather than a familiar arm.
