Research in Yaniv Ziv’s lab focuses on the mechanisms and dynamics underlying long-term memory.
The group is specifically interested in how memory information is coded in the brain, and about what happens, from the neural code’s perspective, to information stored in the brain over timescales that range from days to months: How do memory representations evolve as a function of time and experience? How do neuropsychiatric and degenerative disorders alter memory representations? How do plasticity mechanisms, such as adult neurogenesis, contribute to processing of memory information? The team investigates how memory information is coded by large neuronal populations in brain circuits that are important for memory processing. Group members do that by combining novel in-vivo optical imaging techniques for longitudinal recordings of neuronal activity in freely behaving rodents, genetic tools for manipulating neuronal activity in specific cell types, and computational approaches we develop for longitudinal analysis if neuronal activity data.
