VPH 214/VPH 216
A leading expert on nematode neurobiology, Dr. Davis spent 20 years as a research scientist at the University of Wisconsin-Madison before coming to teach and do research at Northwestern College. His research in the area of neuropharmacology helps lead to new or better drugs that combat parasites in developing countries. In 2001, Davis was awarded a multi-year, $570,000 grant from the National Institutes of Health (NIH) to continue his research at Northwestern with the help of student researchers. In 2006 the NIH continued funding his research with another three-year grant worth nearly $200,000. Since receiving the grants, Davis has trained approximately 20 undergraduate research students in his lab. Most have gone on to medical school or graduate school in biochemistry, physiology or neuroscience.
Davis has done postdoctoral research at the University of Wisconsin-Madison and at the University of North Carolina (Chapel Hill) School of Medicine in Physiology. He teaches human anatomy and physiology, human anatomy, histology, neuroscience, bioethics and the neuroscience and persons seminar and is the director of Northwestern’s Neuroscience and Persons (NAPs) program.
Neuroscience (4 credits; alternate years, consult department) Introduction to the structure and function of the nervous system, emphasizing neuroanatomy, neurophysiology, neuropharmacology and aspects of neuropathology. Multiple levels will be explored from the molecular and cellular levels through brain and spinal cord networks that contribute to complex behavioral and cognitive function. Prerequisites: BIO102 or 221 or permission of instructor.
- Human Anatomy and Physiology
Human Anatomy and Physiology (4 credits) (IGE option under Science and the Natural World) An introduction to the structure and function of the human body.
- Human Anatomy
Human Anatomy (4 credits) A study of the gross structure of the systems of the human body. Prerequisite: BIO102, 115 or permission of instructor.
Histology (4 credits; alternate years, consult department) A study of the microscopic structure of cells, tissues and organs in vertebrate animals with special emphasis on human tissues. An effort is made to correlate structure and function and highlight important pathologies. Prerequisites: BIO115 and 116.
- Neuroscience and Persons Seminar
Neuroscience and Persons Seminar (2 credits; alternate years, consult department) Interdisciplinary lectures, discussions and presentations related to the reading and critiquing of literature on selected topics in the area of neuroscience and persons. Student-led discussions and presentations (oral and written) will be emphasized. Possible topics include: artificial/machine intelligence, clinical neuroscience and neuropathology, cognitive neuroscience, neuroscience and Christianity, neuroscience of emotion, neuroethics, neuromodeling, neuroscience of mental illness, neurophilosophy, neurotheology and social neuroscience; consideration of NAPs-related student research may also be included. Prerequisite: BIO340 or permission of instructor.
