Neurobiology of Learning and Memory I
The aim of this course is to engage students in thinking about and discussing fundamental issues in research on neural mechanisms of learning and memory.
The aim of this course is to engage students in thinking about and discussing fundamental issues in research on neural mechanisms of learning and memory. Topics include the neural mechanisms of learning, memory, emotion, and addictive behavior. Students will be expected to read original reports including classical papers as well as recent advances. The course includes an experimental requirement in which students must design and conduct an experiment related to learning and memory mechanisms of the brain.
Historical perspectives on learning and memory. Classification of learning and memory functions. Theories of memory and learning.
Experimental models of memory. Developmental plasticity. Anatomical plasticity. Conditioned reflexes. Imprinting. Extinction. Forgetting.
Synaptic plasticity: Homosynaptic and heterosynaptic plasticity, long-term potentiation, long-term depression. Spike-timing dependent plasticity.
Cellular mechanisms of synaptic plasticity. Intracellular messages, retrograde messages, receptor phosphorylation, protein synthesis, gene expression, synaptic tagging. Amino acid receptors. AMPA, NMDA, mGluR, nitric oxide.
Invertebrate models. Aplysia, honey bees, drosophila. Sensitization of reflexes.
Neural circuits for reinforcement learning. Substrates of reward and punishment.
Neuromodulation and memory. Dopamine, acetylcholine, serotonin, other neuromodulators. Volume transmission.
Cellular mechanisms of reinforcement. Neurochemical basis. Habits, action-outcome learning, behavioral flexibility.
Memory and aging. Amnesia. Memory enhancers.
Neurochemistry of emotion. Drugs and mood. Addictive behavior.
Students will be required to: (i) prepare and present a lecture on the neural basis of a higher integrative function (40%); (ii) design and conduct an experiment on learning and memory (40%); (iii) participate in class discussions (20%).
Students should have previously taken at least two basic courses in neuroscience or have completed the equivalent by documented prior learning
