Why is it informative to study people with damage to certain regions of the brain?

Studying individuals with damage to specific brain regions provides valuable insights into the functions of those areas, revealing how they contribute to behavior, cognition, and emotion. This approach, often referred to as lesion studies, allows researchers to link particular deficits to brain structures, enhancing our understanding of neural pathways and mechanisms. Additionally, it can inform the development of targeted therapies and rehabilitation strategies for brain injuries and neurological disorders. Overall, such studies deepen our comprehension of the brain's complexity and its role in shaping human experience.
