Hugh (Tad) Blair


The Blair lab's research combines experimental neurophysiology with computational modeling to investigate basic principles of neural computation in the nervous system, with special emphasis on the role of oscillations in neural information processing. The laboratory studies how learning alters neurons and synapses to form memories, and how these cellular changes are ultimately responsible for changes in behavior. Key approaches in his laboratory include behavioral neuroscience and single unit recordings of neural activity from awake, behaving rats during associative and spatial learning tasks.
