NEU 221: Animal Models of Degeneration and Regeneration in the CNS

Winter quarter, 2007

Instructors: David Kang and Binhai Zheng

Place: Leichtag Biomedical Research Building, Room 2A05

Time: 1 - 3 pm every Tuesday (1/9/07 - 3/13/07)

Course descriptions: This course will include discussions on selected papers in degeneration and regeneration of the mammalian central nervous system that utilize animal models to address molecular and cellular mechanisms. Each student is assigned one or more seminal/important research papers to present. All students are expected to read assigned background materials and research papers in advance in order to engage actively in the discussions. Topics to be addressed will include Alzheimer's, Parkinson's, frontotemporal dementia, ALS, spinal cord injury, among others. Students in all graduate and medical programs with the appropriate background are encouraged to register. Some background knowledge in molecular and cellular biology, biochemistry, genetics and neurobiology is expected.
