Biology 202, Neurobiology and Behavior, Spring, 1997


GENERAL INFORMATION


Course instructor: Paul Grobstein Room 107, 526-5098, pgrobste@brynmawr.edu

Prospectus: The objective of this course is to introduce you to the prospects and problems of trying to understand behavior in terms of nervous system function. It is a comprehensive treatment neither of research on the nervous system nor of that on behavior, but rather a consideration of the relations between the two. As such, it is largely a course on how to identify and investigate problems rather than one intended to convey a defined body of information, and may be of interest to students expecting to do more advanced work in any of a variety of disciplines. The most important parts of the course are the lectures and associated discussions, and your active engagement with and contributions to the material and issues treated in the course. Readings are intended to provide background information and illustrative examples, as well as initial sources to allow you to begin exploring subjects of individual interest.

Readings: The required texts are The Workings of the Brain and The Perceptual World, both collections of Scientific American articles which are available for purchase in the bookstore. Assignments in these texts are indicated by asterisks on the accompanying Reading Schedule. Other assigned readings on the Reading Schedule are additional Scientific American articles which are on reserve in the Collier Science Library. Students interested in more detail on basic cellular processes or relevant aspects of the vertebrate nervous system may want to supplement assigned readings with appropriate chapters from Kandel and Schwartz, Principles of Neural Science, which is also on reserve in the Collier Library. Recent issues of Scientific American, the journal Trends in Neuroscience, and Annual Reviews of Neuroscience (all available in Collier Library) are good starting places for further reading on many aspects of neurobiology and behavior. The World Wide Web provides an additional accessible, large, and constantly evolving set of starting points which can be conveniently explored beginning at http://serendipstudio.org.

Organization: The class will meet biweekly for lecture/discussions as shown on the accompanying Lecture Schedule. In addition to exams (see below), students will be expected to submit weekly short essays (one page or less) by e-mail. With permission of students, these will be posted on the WWW site, Serendip. I will be happy to meet individually with students at mutually convenient times, as shown on a weekly calender and sign up sheet outside my office.

Examinations and grading: There will be two mid-terms and a final examination, all in an open-book, take-home, essay format. You will be expected to display the kind of familiarity with concepts and methods of asking and answering questions which comes not only from listening and reading, but from having also thought through aspects of the course material and related them to one another and to whatever additional relevant information you have yourself. You will not be asked for particular facts but will be expected to display in your writing the kind of attention to and respect for facts which is basic to scientific discourse and fundamental to understanding any scientific concept. You will also be expected to display an ability to communicate clearly and cogently. Mid-term exam questions will be distributed Thursday, 20 February, and Thursday, 3 April. Exams will be due at the beginning of lecture on the following Tuesdays. The final exam will cover the entire course with an emphasis on the later topics. The final exam, and the two midterms collectively, will contribute equally to the final grade, with adjustments for classroom and newsgroup participation.
