Pathophysiology of Sleep and Sleep Disorders

Thursdays 10/23/08-12/4/08 2:30-5:30 pm except for the Thanksgiving week, when we will meet on Tuesday 11/25.

Course Summary

This is a 7-week seminar course where literature involving the neurobiology of sleep and sleep disorders will be discussed. The format will consist of a round table discussion of 4-7 primary papers, distributed to students the previous week. Each session will begin with a 10-30 minute introductory lecture by a either Drs Pack or Raizen or by another member of the faculty with relevant expertise. This will be followed by discussion of the papers, which will be led by the students with faculty input.
The goals of this course are:
  1. To teach students some of the outstanding questions in sleep science and sleep medicine.
  2. To guide students through the reading of influential papers in the sleep research field.
  3. To introduce students to some of the methodological approaches in sleep science. To learn the relative merits and weaknesses of various approaches.
  4. To help student gain an appreciation for the difference between circadian rhythms and sleep and the overlapping roles of genes in circadian and sleep regulation.

The course will be opened to post docs, fellows and advanced undergraduate students in addition to graduate students. Students or post-docs who audit the course with the instructors' permission are required to read all the papers and to participate in the discussion. i.e. expectation of auditors will be no different from expectation of credit students.

FACULTY: Along with Dr. David Raizen and Dr. Allan Pack, other faculty with expertise relevant to the topic under discussion will be invited to specific classes.

REQUIREMENTS AND GRADING: Students will be graded on attendance and participation in the discussion. Each student will be expected to read all assigned papers each week and in addition will prepare and then lead a detailed discussion on one of these papers. Papers should be read critically and should be approached as one approaches a journal club paper. While in general, papers under discussion will be scientifically sound and carry important conclusions, one should critically read all aspects of the papers including methods, results, the writing, and the conclusions. Some background reading may be required to fully understand some of the papers. Course instructors will be available to help if questions arise while reading the papers during the week before class.
