    following Aβ-injection [19]. 2.5. Behavioral test: Morris water maze (MVM) 2.5.1. Apparatus The Morris water maze test was conducted as described [20‚ 21]. The maze consisted of a circular pool (200 cm in diameter) filled with water (23±2°C) to a depth of 40cm. The circular pool divided into four arbitrary quadrants. A transparent Plexiglas platform (the only escapable thing from the water) 10cm in diameter was submerged 2cm underneath the water surface at the midpoint of one quadrant. There were many

    Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite
