Name: Date: Section #: Lab 3: Neurophysiology Purpose: The purpose of this lab is to test the learning and memory ability of mice. To understand brain activity in humans using an EEG Directions: EXPERIMENT 1 Choose a station with your group. One member from group will attain a small "basket" and another member will choose a mouse. Wearing gloves, pick up mouse BY THE TAIL and place into "basket. Return to station. Once at the station, as a group, decide where you want the platform to be. This platform 1· 2. cannot be moved once decided. This will be the END point for your mouse.

If your mouse has not found the platform after 45 seconds, remove mouse from the water and place it onto the platform. Record this time as 45 seconds. Allow mouse to rest on the platform for 1 minute. Once time is up, take the mouse back to its basket for 30 seconds. Once 30 seconds are up, drop the mouse in the same spot in the water. Repeat this step 9 more times start the 5. 6. 7. Once all trials are completed, place mouse back into its cage. EXPERIMENT 2 1. Follow the step-by-step instructions in Lab Tutor under the lab titled "EEG.
