We study effects of behaviors and environmental conditions (e.g. light pollution, song, social setting, bird migration) on brain plasticity (neurogenesis, recruitment and survival of new neurons, and apoptosis) in birds’ brains. Our goal is to understand the relations between the environment and brain plasticity and investigate how brain plasticity relates to the life of animals. Hopefully, our studies will enable a better understanding of neuronal replacement in the brain and might also lead to ecological and medical applications. My laboratory is located at Tel-Aviv University.
