That is a complicated and very good question. In humans (mammals) neurons are formed during development throughout the cortex. At adulthood, this continues only in the hippocampus and olfactory bulb. Therefore the rest of the cortex is made of all the same neurons for the rest of your life (n.b. you can lose them). Therefore learning new things is probably the result of neuro-placticity rather than neurogenesis.
However, There are two general types of memory; episodic and semantic. Episodic are the ones that you can imagine because you experienced them. As opposed to semantic- dry info you've studied.
Episodic memories seem to be consolidated by the hippocampus which may play memories back during REM sleep. This may be the result of neurogenesis. However, the new cells that are formed will not be the loci of the memories they are the mechanism of storing the memories in the neocortex.

When you learn something new you grow new neurons. What would you say to disprove this statement?
No. You don't grow new neurons, you grow more connections.

Do neurons grow new branches?
Yes
What is the process by which axons of healthy neurons adjacent to damaged neurons grow new branches to make up for the damage?
Collateral Sprouting
Do you get wrinkles in the brain every time you learn something?
We don't start out with wrinkly brains, however; a fetus early in its development has a very smooth little brain. As the fetus grows, its neurons also grow and migrate to different areas of the brain, creating the sulci and gyri. By the time it reaches 40 weeks, its brain is as wrinkled as yours is (albeit smaller, of course). So we don't develop new wrinkles as we learn. The wrinkles we're born with are the wrinkles we have for life, assuming that our brains remain healthy. Our brains do change when we learn -- it's just not in the form of additional sulci and gyri. This phenomenon is known as brain plasticity. By studying changes in the brains of animals like rats as they learn tasks, researchers have discovered that synapses (the connections between neurons) and the blood cells that support neurons grow and increase in number. Some believe that we get new neurons when we make new memories, but this hasn't yet been proven in mammalian brains like ours.
Are the dead neurons in the cortex replaced by new neurons?
yes
What is snapse?
A "synapse" is the gap between neurons in the brain. Since the brain is not hard wired, and the neurons are only connected by a chemical synapse, the brain can be "re-wired" to act in a way it did not before. This is how we are able to learn and perfect new skills.
Can undamaged neurons make new connection with damaged neurons?
yes
How do you grow new braincells?
In the past, scientists thought you couldn't grow any more new brain cells. However, recent study shows that exercise can clean up your brain, remove dead neurons, and form new neurons. So run often, sleep at least 9 hours a day, and eat fruits and vegetables to help keep active.
How can background knowledge help you learn?
The more you know, the more easily you can learn something new. If you know something similar to the new thing, it's very easy to learn the new one, and the more knowledge you have with which to compare new things, the better your chances of finding similarities.
Why is education a daily experience?
Generally someone will learn something new everyday, it doesn't mean that you experience it through School, College or University, it just simply means that you will learn something new.
What is the creation of new neurons?
Neurogenesis
