Neuroscience Major Requirements

(Also see Requirements for a Bachelor's Degree.)

Neuroscience is the study of the nervous system and how it functions. Neuroscientists study the nervous system from all levels, ranging from molecules interacting with cell membranes to brain systems subserving cognitive functions such as language. Dramatic progress has been made at all levels, and the field continues to grow. On the Homewood campus, researchers studying the nervous system are in the departments of Biology, Biomedical Engineering, Biophysics, Cognitive Science, and Psychological and Brain Sciences and in the Krieger Mind/Brain Institute. Their presence provides the opportunity for an innovative, interdepartmental program which offers a broad overview of the neuroscience field, as well as more advanced training in one of four focus areas.

General Information

  • Students are encouraged to complete an optional introductory course in their freshman year, such as AS.200.141 Foundations of Brain, Behavior and Cognition or AS.050.105 Introduction to Cognitive Neuropsychology . Either of these courses will satisfy the prerequisite for AS.080.305 Neuroscience: Cellular and Systems I. Foundations of Brain, Behavior and Cognition will also satisfy the prerequisite for AS.080.250 Neuroscience Laboratory.
  • Students interested in attending medical school will need to take a second semester of organic chemistry and its corresponding laboratory and biochemistry to meet medical school admission requirements; however, these courses are not major requirements.
  • Students are required to select their advanced neuroscience elective courses from one of four approved focus areas: cellular and molecular neuroscience (NEUR-CM), cognitive neuroscience (NEUR-CG), computational neuroscience (NEUR-CP), or systems neuroscience (NEUR-ST). Approved courses fulfilling this requirement are found on the neuroscience website or in the schedule of classes where they can be identified by their POS-Tag.
  • To apply towards the major, all courses must be taken for a letter grade and a grade of C- or better is required.
    ***August 28,2023 - Correction to the Neuroscience, BS requirements: Mathematics, Stiatistics, and Sciences Courses, AS.171.113 Subatomic World should be replaced with AS.110.113 Honors Single Variable Calculus.

For students with Biology credit from an exam (AP, IB, GCE), exam credit may not use credits towards this requirement.  Therefore, these student must take at least one biology course and its lab at JHU.  Students who elect to take General Biology I or II with its lab will lose the corresponding exam credits. 

2

Students planning on taking the MCAT should consider whether or not they have a solid biology background coming into JHU. If they are unsure they should consult with the Office of Pre-Professional Advising and consider taking General Biology I and II along with the associated labs.

3

AS.020.340 Developmental Genetics Lab may also be used for this lab requirement and it may have seats during the fall semester only for Neuroscience majors. AS.250.253 Protein Engineering and Biochemistry Lab OR AS.020.315 Biochemistry Project Lab can be taken either in the fall or spring semester.

4

Research (AS.080.5xx) must be conducted in one of the neuroscience laboratories participating in the program and can in completed in 1 to 3 credits per term. Students must register for two semesters of AS.080.499 Scientific Communication and Mentoring. Students are strongly encouraged to only take Scientific Communication and Mentoring when they are either actively involved in research or have completed at least three credits of research.

Honors in the Major

Effective Fall 2023, the honors requirements are changing from prior years. Students who entered JHU prior to Fall 2023 should refer to their catalogue year of entry to review their honors requirements.  

For students entering JHU in Fall 2023 and beyond, the honors requirements are:

  • Earn a GPA of 3.8 or better in major requirements
  • Earn 6 credits of required research (this overlaps with major requirements)
  • Presentation of research findings at the Day of Research in Engineering, Arts, Medicine and Sciences (DREAMS) during the Fall or Spring semester
  • Receive a recommendation from research mentor

Neuroscience Undergraduate Honors Thesis

The Neuroscience Undergraduate Honors Thesis program is designed for students wishing to distinguish themselves via the writing and defense of a thesis. Students wishing to gain more hands-on experience in the construction of a research hypothesis, experimental design, and scientific communication should consider the thesis. In particular, students thinking about pursuing a career in research may find the preparation of an Undergraduate Honors Thesis will provide valuable insight into the research endeavor.  While this option is new for the 2023-2024 academic year, students who entered in prior years may pursue this opportunity.  

Criteria:

  • Design and conduct an experiment in Neuroscience under the direction of mentor
  • Submit an application, a recommendation letter from the primary mentor, and a research proposal describing your planned project to the Undergraduate Honors Thesis Director (Dr. Robert Ross) during the Spring semester the year before your planned graduation date
  • Earn 9 credits of Independent Research
  • Write an Undergraduate Honors Thesis
  • Defend the Thesis orally to a committee comprised of members from the Johns Hopkins University Neuroscience community by mid-April of your graduation year
  • Present your research at the DREAMS conference Fall or Spring of your final undergraduate year
  • Attend a weekly Honors Thesis Seminar during Spring semester of your graduation year focused on assisting with Thesis writing (Neuroscience Honors Thesis Seminar AS.080.589)
  • Maintain minimum 3.5 GPA in all required courses for the Neuroscience major
