Hippocampus, the Seahorse in your Brain: Where Neurons are Born

A board certified internal medicine physician talks about the hippocampus (Latin for "seahorse"). This is a small area of your brain that is critical for forming new memories. It shrinks with age and is the first brain structure affected by Alzheimer's dementia. It is also the only place in the human brain where new brain cells (neurons) are born throughout life, even as an adult.
