Cellular Basis of Learning and MemoryBIPN 148
Spring 2006April 3-June 9, 2006
This course will examine the cellular and molecular mechanisms that underlie learning and memory. Topics covered will include the role of the hippocampus in learning and memory, neurotransmitter systems and receptors involved in learning and memory, and biochemical mechanisms of synaptic plasticity. Emphasis will be placed on discussing experiments from the primary literature. A solid background in cell and molecular biology is expected.
Prerequisites: BILD 1; BILD 2; BIBC 100/102; BIPN140 highly recommended.
