# Brain Organoids Grown for Years in Lab Track Time Like Real Brains

Scientists have maintained human brain organoids in the lab for multiple years, allowing them to mimic key aspects of brain development and record the passage of time over extended periods. This long-term cultivation offers a new model for studying ageing, neurological disorders, and the fundamental biology of human brain maturation.
