TED Talks Daily You can grow new brain cells. Here's how | Sandrine Thuret
Aug 19, 2021
In this engaging discussion, neuroscientist Sandrine Thuret sheds light on the fascinating process of neurogenesis—the brain's ability to grow new neurons. She clarifies misconceptions about adult neurogenesis, particularly its impact on memory, mood, and cognitive functions. Thuret provides practical tips on how diet, lifestyle choices, and mental exercises can enhance this process. She even links neurogenesis to improvements in mental health, such as alleviating depression, making the case for a proactive approach to brain health.

Oncologist's Puzzle
- Sandrine Thuret discussed neurogenesis with Robert, an oncologist, who was puzzled by patients experiencing depression after cancer treatment.
- Thuret explained that cancer drugs, while effective in stopping cancer cell growth, also hinder the production of new neurons in the brain.
Neurogenesis in Adults
- Neurogenesis, the growth of new brain cells, occurs in adults, specifically in the hippocampus, a brain region crucial for learning, memory, and mood.
- By age 50, the neurons we are born with in the hippocampus will have been replaced by adult-born neurons.
New Neurons and Memory
- New neurons are vital for learning, memory, particularly spatial navigation.
- Blocking neurogenesis impairs certain memory functions, especially spatial recognition, highlighting their crucial role.
