Duke TIP Summer Studies Program 2011
Duke University West, Term 1
Instructor: Arianna Tamvacakis
Teaching Assistant: Claire Ober
Required materials: notebook or loose-leaf paper; pens and pencils.
Texts and other materials will be supplied by TIP.
Course description and objectives:
One of science’s final frontiers lies within our own bodies: the human nervous system. Neuroscience is the interdisciplinary study of the nervous system, incorporating such fields as anatomy, physiology, biology, ethology, pharmacology, pathology, philosophy, and psychology, to name a few. The job of the neuroscientist is to understand how information from the environment is translated into sensations, thoughts, and behaviors. Neuroscientists today grapple with complex problems such as: how does the brain learn, what is the neural basis of consciousness, and what underlies debilitating neurological disorders and diseases?
The purpose of this course is to utilize critical thought to understand and integrate properties of the human nervous system. To this end, students will analyze various aspects of neuroscience to study human nervous system functions and disorders.
The objectives of this course are that students will:
Understand the anatomy and physiology of the nervous system and its components.
Gain exposure to some of the many aspects of neuroscience.
Analyze human behaviors in the context of nervous system anatomy and physiology.
Synthesize and evaluate theories explaining how the nervous system functions.
Develop social and team work skills through group discussions and presentations.
Develop critical reading skills using scientific research articles and undergraduate-level texts.
Develop critical thinking habits by considering complex issues related to neuroscience.
Analyze moral and ethical issues related to neuroscience.
Access information via online biomedical databases.
Assignments and Evaluations:
This course will be presented as a series of topics, starting with basic nervous system anatomy and building up to complex issues of cognitive neuroscience. Important components of the course will be the ability to think critically about a given topic, to research a topic independently, and to present one’s results orally. Assignments will include critical evaluation of texts, short videos, and primary research articles presented via discussions, writing assignments, research projects, and presentations. While assignments will not be graded and no exams will be given, students will be evaluated on their use of critical thinking and their ability to communicate their understanding of course material to others.
The ultimate objective of the course is to facilitate a connection between the student and neuroscience. Even if students do not later choose a career in science, the teamwork and critical thinking skills gained from this course will benefit them many years into the future.
Week 1: Cellular and Gross Nervous System Anatomy and Physiology; Sensory and Motor systems.
Monday June 13th
Introductions and cellular neuroscience
9am – 12pm: Introductions
Students, instructor, and T.A. will introduce themselves. Students will fill out a brief questionnaire, and go over classroom conduct rules, who to speak to if they have a problem, etc.
Group discussion: what does “neuroscience” mean? T.A. and instructor will write key words on the board while having students talk about how they define “neuroscience” to illustrate that it is a term that can mean many things to many different people.
