BA in Biology—Neurobiology Specialization

Our understanding of the human brain and diseases of the nervous system is rapidly expanding. The Neurobiology specialization for Biology majors provides an opportunity for students to understand the brain from a biological perspective, combining a broad-based biology education with access to advanced neuroscience courses. In addition, students will have research opportunities in areas such as sensory biology at cellular, network, and behavioral levels; the cellular and molecular mechanisms of neurological diseases and dysfunctions including Alzheimer’s disease, autism, neuronal cell death, and traumatic brain injuries; neuroethology; computational and network analysis of sensory-motor learning; and membrane excitability at a subcellular level. Upon completion of this specialization, students are prepared for careers in the biotechnology industry and for graduate studies in the biomedical sciences and medicine.


The specialization in Neurobiology requires a total of 12 biology courses (introductory, foundation, breadth, and elective courses). Students must also complete a total of six to seven related courses in chemistry, math/computer science, and physics.

Beyond Introductory Biology, at least three major courses must be at the 300+ level and three major courses must be lab courses taken in the BU Biology Department (the 300+ and lab requirements can overlap).

A grade of C or higher is required for major credit in all courses except corequisite chemistry courses. A grade of C– or higher is required for major credit in corequisite chemistry courses.

Course titles and full descriptions are located in the Courses portion of this Bulletin. Unless otherwise noted, all required courses are 4 credit hours.

Introductory Biology (2 courses)

  • CAS BI 107 (or CGS NS 201)
  • CAS BI 108 (or BI 116)

Foundation Courses (3 courses)

  • CAS BI 203 (or BI 213 or BI 218*)
  • CAS BI 315*
  • CAS BI 325 (or NE 203*)

* Course will also count toward the three-lab requirement.

Breadth Requirement (1 course)

Ecology, Behavior, Evolution (EBE)

  • CAS BI 225 or
  • CAS BI 260 or
  • CAS BI 303* or
  • CAS BI 306* or
  • CAS BI 309 or
  • CAS BI 407* recommended

* Course will also count toward the three-lab requirement.

Note: A course cannot fulfill a breadth requirement and a Neurobiology elective simultaneously.

Neurobiology Electives (6 courses)

Choose six elective courses from the following list and/or from the eligible courses under the Optional Programs section of this Bulletin page. Three electives must be BI (or BI cross-listed) courses.

  • CAS BI/NE 230
  • CAS BI 407*
  • CAS BI/CH 421*
  • CAS BI/NE 445*
  • CAS BI/NE 449*
  • CAS BI 455
  • CAS BI 481
  • CAS BI 502
  • CAS BI/NE 520
  • CAS BI/NE 525
  • CAS BI/NE 535
  • CAS BI/NE 542
  • CAS BI 551
  • CAS BI 552
  • CAS BI 594
  • CAS BI 599
  • CAS CH 373
  • CAS PS/NE 333
  • CAS PS 336
  • CAS PS/NE 337
  • CAS PS/NE 338
  • CAS PS 339/NE 202
  • CAS PS/NE 528
  • CAS PS/NE 530
  • CAS PS/NE 544
  • SAR HS 370 (NOT accepted toward laboratory requirement)
  • SAR HS 550

* Course will also count toward the three-lab requirement.

Note: After introductory biology, a minimum of five courses must be taken in the BU Biology Department (i.e., have a CAS or MET BI or BI cross-listed course designation). A maximum of four MET courses may be counted as credit toward the BA degree. In addition, at least three courses must be at the 300+ level and three must have a laboratory component. Some of these requirements can overlap (e.g., BI 315 simultaneously counts as a breadth requirement, a 300+ level course, and as a lab toward the three-lab requirement). Nonetheless, it is counted only as a single course toward fulfillment of the major.

Required Requirements (6–7 courses)


Choose one of the following tracks (in consultation with your major advisor):

Standard track (recommended):
  • Choose one of the following general chemistry sequences:
Sequence I Sequence II Sequence III
CAS CH 101 &
CAS CH 102 (or CH 116)
CAS CH 109 &
CAS CH 110
CAS CH 111 &
CAS CH 112


  • Choose one of the following organic chemistry courses: CAS CH 203 (or CH 211 or CH 218)
Alternative track (not acceptable for most pre-health careers):
  • CAS CH 171^

^ Or any completed general chemistry sequence from the standard track


  • CAS CH 172 or CH 174

Note: It is recommended that the standard track general chemistry sequence (or alternative track’s CH 171 & 172 or CH 171 & 174) be taken concurrently with BI 107 and BI 108 during freshman year. Most Biology majors complete the standard track and continue onto a fourth semester of chemistry (CH 204 or 214), which is a requirement for medical and other professional schools. Students contemplating application to medical school are also advised to take biochemistry (CAS BI 421/422 or CH 373) in their junior or senior year.

Mathematics/Computer Science

Choose two courses from the lists below. At least one course must be calculus or statistics:

Calculus Courses
  • CAS MA 121
  • CAS MA 122
  • CAS MA 123
  • CAS MA 124
  • CAS MA 127
  • CAS MA 129
  • CAS MA 196

Note: Students cannot take more than one of the following for credit: CAS MA 121 or 123; similarly, students cannot take more than one of the following for credit: CAS MA 122, 124, 127, or 129.

Statistics Courses
  • CAS MA 115
  • CAS MA 116
  • CAS MA 213
  • CAS MA 214

Note: MA 113 will not satisfy major requirements. Students cannot take more than one of the following for credit: CAS MA 113, 115, or 213; similarly, students cannot take more than one of the following for credit: CAS MA 116 or 214.

Computer Science Courses
  • CAS CS 105

Optional Programs

Undergraduate Research in Biology

While research is not required by the major, undergrads are encouraged to participate in research during their time at Boston University. Undergraduate research courses are available at all levels and require students to submit an application and receive approval by the Director of Undergraduate Studies.

Freshman BI 191/192 2 credits
Sophomore BI 291/292 2 credits
Junior BI 391/392 2 or 4 credits
Senior BI 491/492 4 credits
Senior (Honors) BI 401/402 4 credits

Notes: Up to two 4-credit semesters can be used to fulfill major electives (these semesters do not need to be taken consecutively). One of these two semesters can be used toward the three-lab requirement. Both 2- and 4-credit research count toward graduation credits.

Honors Research in Biology (CAS BI 401 & 402) requires an overall GPA of 3.5. Students must complete two semesters of 4-credit research and one semester of the Honors Seminar (CAS BI 497/498). Honors students must complete and defend a written senior thesis.
