Physiology and Neuroscience

This major provides a program for studying the bodily and neural functions of complex organisms. Students may concentrate upon a more specialized area of study, such as neurobiology, animal physiology, or endocrinology.

This major is designed to provide students with the fundamental courses required for entry into medical school, graduate school in biological or neural sciences, or entry into other health related professions such as nursing, dentistry, veterinary medicine, pharmacy, physical therapy, physical education, agriculture and wildlife management.

The major requirements below apply to students who were admitted to UC San Diego in Fall 2016 or later.  If you were admitted to UC San Diego prior to Fall 2016, please refer to your degree audit, the UC San Diego General Catalog, or academic plan that aligns with your admit term for a listing of major requirements.  If you have further questions, please contact a Biology Advisor for clarification.

Lower-Division Requirements

  • BILD 1, 2, 3, and 4

    Note: Effective Fall 2015, entering freshmen are required to complete Introductory Biology Lab (BILD 4). Transfer students will be held to the new requirement beginning Fall 2017.

  • Chemistry 6A, 6B, 6C, and 7L
  • Mathematics 10A, 10B, and 11 or 20A, 20B, and 11
    Note: Effective Fall 2016, entering freshmen are required to complete Calculus-Based Introductory Probability and Statistics (MATH 11).  Fall 2016 and 2017 entering transfer students may complete either MATH 10C, 20C, or 11 to satisfy the math sequence.  Transfer students will be required to complete MATH 11 beginning Fall 2018.
  • Physics 1A/1AL, 1B/1BL, and 1C/1CL or 2A, 2B, 2C, and one lab (2BL, 2CL or 2DL)

Upper-Division Requirements

  • Physiology and Neuroscience (P&N) Core Courses - complete two of the following courses:
    • Human Physiology II (BIPN 102)
    • Comparative Physiology (BIPN 106)
    • Biology and Medicine of Exercise (BIPN 108)
    • Cellular Neurobiology (BIPN 140)
    • Systems Neurobiology (BIPN 142)

    • Diseases of the Nervous System (BIPN 150)
    • The Healthy and Diseased Brain (BIPN 152)
  • Upper-Division Biology Electives - complete three upper-division biology courses (each course must be at least four units) offered by the UC San Diego Division of Biological Sciences.
    • One quarter of BISP BISP 195 and/or one quarter of either BISP 196, 197 or 199 may be applied to this requirement. Subsequent quarters of BISP 195, 196, 197 or 199 may be applied toward college and university requirements.
    • The following Scripps Institution of Oceanography courses may be applied to this requirement: SIO 123, 125, 126, 127, 128, 132, 133, 134, 147, 181 and 189. Students are required to meet the Division of Biological Sciences residency requirement.

Additional Requirements

Minimum Grade Requirement

  • All courses required and used toward any biology major requirements must be passed with a grade of “C-“ or better.
  • The minimum grade requirement applies to all lower-division, upper-division, required courses taken in other departments, as well as courses transferred and used toward major requirements.
  • Exceptions will be made for those required courses that have a P/NP only grading option (e.g., BISP 199).
  • The minimum major GPA requirement is 2.0.

Please note: The degree audit may not automatically reject D grades for the major. If your degree audit appears blue and you have a D in a required course for the major, please contact a biology advisor.


Upper-Division Unit Requirement

To receive a Bachelor of Science from UC San Diego, all students must complete 48 or more units of upper-division course work within the major.


Biology Residency Requirement

To receive a Bachelor of Science in Biological Sciences from UC San Diego, all students must complete at least twenty units of upper-division coursework in the Division of Biological Sciences with a grade of C- or better. This coursework must directly apply to the student’s Biology major requirements, and must be taken while officially enrolled at UC San Diego. Courses completed outside of the UC San Diego Division of Biological Sciences will not be counted toward the residency requirement.
