Clarissa Parker is an Associate Professor of Psychology and Neuroscience at Middlebury College. She arrived at Middlebury in 2013, after completing a post-doctoral fellowship in the Department of Human Genetics at the University of Chicago. Clarissa received a B.A. in Psychology (with a minor in Philosophy) from Colorado College, and a Ph.D. in Psychology (with a concentration in Neuroscience and a certificate in Behavioral Genetics) from the University of Colorado.
Psychiatric disorders affect millions of individuals, and disrupt some of the most fundamental human attributes such as thought, perception, mood, and even sense of self. The relative genetic contribution to psychiatric disorders is well known, yet identifying the underlying molecular mechanisms has proven difficult. Clarissa’s research uses the relative simplicity of mouse models to develop concepts, test neurobiological hypotheses, and identify genes that underlie traits with relevance to human psychiatric disorders. Her recent work has focused on behaviors that can be measured in both mice and humans; including conditioned fear (a model of anxiety and post-traumatic stress disorder), pre-pulse inhibition (a neurological phenomenon associated with schizophrenia) and methamphetamine sensitivity (a trait indicative of drug reward). This approach has provided fundamental insights into the neurobiology underlying these traits and a better understanding of the mechanisms by which genes influence behavior. In her free time, Clarissa enjoys yoga, fly fishing, and splitting wood.

Behavioral Neuroscience
Course Description
Fundamentals of Behavioral Neuroscience
Behavioral neuroscience is an interdisciplinary field that combines approaches and knowledge from psychology, biology, and chemistry to further our understanding of human and non-human animal behavior. In this course, you will study the interrelationships among elements of the nervous systems, co-functioning bodily systems, and behavioral output such as emotions, sex, memory, consciousness, sleep, and language. You will be given an opportunity to apply your knowledge from NSCI 0251 of the nervous system at the micro and macro levels and will revisit the basic concepts of behavioral genetics and psychopharmacology. This cumulative knowledge base will serve as your foundation for advanced study of neural systems and their relative roles in progressively more complex behaviors such as basic reflexes, motivation, rational thought, neural disorders, and therapeutic efficacy. (PSYC 0105 and NSCI 0251; open to NSCI majors only, others by approval) 3 hrs. lect./3 hrs. lab.

Behavioral Genetics
Why are some people shy while other people are very outgoing? Why do some people do well at school while others struggle just to pass? This course examines the roles that genes and the environment play in creating individual differences among us humans. In order to answer these questions, this course will cover topics including molecular genetics, Mendelian genetics, metabolic disorders, chromosomal disorders, linkage and association designs, and the genetics of complex disorders.

Directed Research
Course Description
Directed Research in Psychology
Directed research provides opportunities for advanced students to become familiar with and participate in ongoing research projects under the direction of a faculty member. The student will first read background literature on the content area to be investigated and experimental methodologies to be used. Procedures involved in conducting psychological research will then be learned through firsthand experience. Potential activities include the design of research and the defining of conceptual variables and the gathering, analyzing, and interpretation of data. Finally, students will learn how to write technical articles in psychology by preparing a paper describing the project, using APA style. (Approval required; not open to first-year students) 3 hrs. lect.

Genes, Brain, Behavior
Course Description
Genes, Brain, and Behavior
What we experience—and how we experience it—is influenced by our unique combination of genes. For better or worse, the gene variants we inherit from our parents contribute to our predispositions to psychological disorders, our personalities, and even the way in which we perceive the world around us. To be clear, anything that you can do or think is in some way influenced by your genes. However, this statement comes with a large caveat: except in the case of (relatively) rare single gene mutations, your genes do not determine but rather contribute to who you are. Working within the field of behavior genetics, we will cover topics such as social behavior, sexual promiscuity, drug abuse, language, intelligence, and psychopathology. (PSYC 0226 or BIOL 0145 or NSCI 0251; Open to junior and senior psychology or neuroscience majors only, others by approval) 3 hrs. sem.
