What Is Neurogenesis, and What Role Does It Play in Treating Depression?

Read Transcript

Neurogenesis is the different form of neurogenesis, but what we're really talking about is adult neurogenesis. So the idea is that we believe that we were born with a certain number of brain cells and we can't generate new ones. But that changed almost 20 years ago when people like Elizabeth Gould showed that the adult brain can actually continue to form new neurons throughout life.

It tends to decrease with age but it continues and mainly in two regions. Mainly in the olfactory bowl, which is for smell, and the other is the hypocampus. And psychiatrists very interested in neurogenesis even if it happens because things that make us depressed tend to supress neurogenesis, things that make us feel better into increased neurogenesis and there's some evidence, and it's always consistent, but there is some studies that show if you block neurogenesis lose it.

So the belief is that neurogenesis may be playing a key role in at least one keeps up population of people with depression in theory. The excitement there is that we're beginning to finally understand the fundamental mechanism that lead to depression. In other parts of the brain the excitement is that there in not ongoing neurogenesis or the belief is still controversial that there is when you we're just in the cortex, but there are stem cells that can be induced to become neurons.

So the excitement there is someday in the future we may be able to get this timescales to grow and repair the neuron degenerated condition lips in the outside satisfaction to be able to treat strokes potential is there.
