Neuroscience

Understanding the brain and the nervous system

Overview   |   Meet An Earlhamite   |   Our Faculty   |   Plan of Study   |   Courses  

 

Neuroscience at Earlham focuses on understanding the brain and the nervous system, seeking to answer questions about the brain, behavior, thought, memory, emotion, or neuropsychiatric disease.

You will have unparalleled access to and attention from our Biology and Psychology faculty who will know you and who will use their resources and networks to help you find and follow your career path.

Required courses for the major introduce students to the fundamentals. They are followed by exploration of special topics in advanced courses chosen to best serve your interest.

You will conduct original research in your courses, work with faculty on research projects, and then complete an in-depth neuroscience research project in your senior year.

Paid summer internships are available at the Stark Neuroscience Research Institute of the Indiana University School of Medicine.

Highlights

In an anatomy and physiology course, students perform a dissection of a human cadaver, including an examination of the human brain and spinal cord. Seeing, holding, and dissecting a real human brain is an amazing experience that few undergraduates can get.

Neuroscience majors pursue graduate studies in medicine, other health professions, veterinary medicine or graduate study in cellular, molecular, behavioral or systems neuroscience.

Recent graduates have gained admission at Georgetown, Indiana and Purdue universities as well as the Southern College of Optometry. Yim Rodriguez ’14 earned a full-tuition scholarship to the prestigious Munich Brain Course at Ludwig-Maximilians-Universität.

Our alumni pursue a wide variety of careers including medicine, physical therapy, occupational therapy and scientific research.

Exploring Beyond Her Major

Meredith believes a liberal arts education at Earlham provides the freedom to choose one's own academic adventures and doesn't pigeonhole one into a Pre-Med track.

Plan of Study

Planning Ahead

Students planning to major in Neuroscience should speak with a faculty member in Biology or Psychology early in their undergraduate career. Faculty will help lay out a four-year plan that includes required courses, elective courses that support the specific neuroscience area of interest, opportunities for off-campus study and possible internships. Early consultation is important to sequencing of several courses so study remains an option off-campus. In general, students should take CHEM 111 in their first semester, CHEM 221 and BIOL 112 in their second semester, and BIOL 341 in the fall of their Sophomore year. Students should take BIOL 242 in their Sophomore or Junior year. Students should begin taking courses in psychology by the end of their Sophomore year. A summer research experience is highly recommended and faculty will work with students to identify appropriate opportunities.

Original Research Project

After thorough grounding in the fundamentals of Biology and Psychology followed by exploration of special topics in advanced courses, the Capstone Experience for the Neuroscience major is the completion of an original research topic that integrates Psychology and Biology. For example, student projects have investigated the relation between infant attachment style, response to a novel situation, and stress measured by salivary cortisol. Another student examined drug-induced changes in aggressive display in male Siamese fighting fish. A third project measured small facial muscle movements in response to happy or angry faces and the subsequent identification of facial expressions of emotion in briefly presented images.

General Education Requirements

Many of the required courses for the Neuroscience major fulfill the Scientific Inquiry Requirement and Quantitative Reasoning component of the Analytical Reasoning Requirement of the General Education Requirements.

The Major

Students generally complete 44 (12 courses plus a 1-credit seminar) for the Neuroscience major.

Students interested in post-graduate study, including medical school, should review entrance requirements of the programs in which they are interested, since many programs require physics, calculus and additional chemistry courses. Students interested in taking Biochemistry are reminded that the prerequisites for this course are CHEM 111, 221, 321 and 331. Students who are interested in taking Animal Behavior should take Ecological Biology (BIOL 111) and Biological Diversity (BIOL 226) in their first two years. Students interested in Ornithology, Biology of Insects and/or Vertebrate Zoology are reminded that Ecological Biology (BIOL 111) is a prerequisite.

With approval from Neuroscience faculty, specialty courses that are offered on an occasional basis may substitute for one or more of the elective courses.
