Cognitive and Behavioral Neuroscience B.S. (PC34)
Did you enroll at the University during or after Fall 2026? These major requirements do not apply to you. Please find your major requirements in our Majors Effective Fall 2026.
Cognitive and Behavioral Neuroscience (CBN) is a joint major between the Department of Cognitive Science and the Department of Psychology.
The B.S. in Cognitive and Behavioral Neuroscience will appeal to students who are broadly interested in understanding links between neural activity and perception (e.g., color vision, attention), basic behaviors (e.g., appetitive drives), and higher-level cognitive function (e.g., working memory and executive function) using multiple tools ranging from single-unit physiology to functional magnetic resonance imaging (fMRI) and electroencephalography (EEG).
Major Requirements
- All upper-division (UD) courses numbered 100-193 must be taken for a letter grade and a minimum grade of C- is required for the course to count toward the major.
- Courses taken Pass/No Pass cannot count toward the upper-division (UD) CBN major requirements.
- Excluded from credit towards the major are graduate seminars (2XX).
- A maximum of three upper-division (UD) courses toward the major may be taken outside of UC San Diego.
- A grade-point average of at least 2.0 in the upper-division (UD) major courses is required for graduation.
Lower-Division (LD) Requirements (36 units)
Cognitive and Behavioral Neuroscience (CBN) uses scientific tools and concepts: knowledge of formal systems such as logic or calculus, probability theory, computer science, chemistry, biology, physics, and statistics. Accordingly, students in upper-division (UD) courses must have an adequate background in these topics.
Lower-division (LD) courses for the major should be completed by the end of the sophomore year. These requirements will guarantee an adequate background for the topics of the upper-division (UD) CBN courses.

B.S. Research Paper (may be titled "Research Experience")
^Students who use at least one of the Research Lab courses from the list above, do not have to submit a B.S. Research paper to the Psychology Advising Office.
**Students who satisfy their research requirement using 8 units of PSYC 199 or COGS 199 are required to submit a B.S. Research paper to the Psychology Advising Office to fully satisfy their B.S. major requirements. You can learn more about the B.S. Research Paper Guidelines on our website.
B.S. Research Paper section on your Degree Audit: must be manually cleared by a Psychology advisor; therefore, even if you are not required to write a B.S. Research paper, this section will not be marked complete until after one of the advisors reviews and approves your Degree and Diploma Application (DDA).
