Building A Brain - Mysteries of the Brain

The video explores the role of the nervous system and brain in animal behavior, focusing on neural circuits. Carlos Aizenman and his team at Brown University study the development of these circuits using tadpole brains. They investigate how environmental interactions shape neural pathways, particularly in the optic tectum of Xenopus laevis. Through electrophysiology and behavioral experiments, they aim to understand normal and abnormal neural development, contributing to broader insights into brain function.
