Students are encouraged to declare the major when they are in their sophomore year, before selecting their courses for the Fall semester of their Junior year. All students wishing to declare the Neuroscience major must have successfully completed, or be currently enrolled in, BBB 109: Introduction to Brain and Behavior. Students should meet with their College Advisor to have their Penn InTouch worksheet updated and made official. Students must then download and complete the Major Declaration Worksheet and save the file as "Neuroscience [LastName]". Students should make an appointment with a Neuroscience advisor during advising hours to officially declare the major.
