You can grow new brain cells. Here’s how. | TED talk by Sandrine Thuret
I’d always thought that our brains grow in childhood and then remain the same size for the rest of our lives.
It turns out that the adult brain continues to grow new brain cells (neurons) throughout our lives. Each day in the Hippocampus (an area of the brain associated with memory, learning, mood and emotion) we grow approximately 700 new neurons.
That might not sound like much… but it means that by the age of 50 every person will have replaced every single neuron in their Hippocampus through a process called neurogenesis.
The process itself is pretty fascinating but the part that really grabbed me in Sandrine Thuret’s TED talk is the idea that we can affect the rate at which these new brain cells develop. If we do the right things, we can train our brains to grow at a faster rate!
