What is Ventromedial prefrontal cortex (vmPFC)?

The ventromedial prefrontal cortex is like the brain’s wise friend who helps you decide what feels good and what feels bad.

Imagine your brain is a big city with many neighborhoods, and one of them is called the prefrontal cortex, it's in the front part of your brain. Now, inside this neighborhood, there’s a special house called the ventromedial prefrontal cortex, or vmPFC for short. This house is like a cozy living room where you think about things that make you happy or sad.

When you're choosing between two snacks, say, chocolate or an apple, your vmPFC helps you remember how sweet the chocolate feels and how healthy the apple is. It’s like having a little helper who reminds you of past experiences so you can make better choices now.

Think of the vmPFC as the brain's memory keeper for feelings. When you try something new, like a funny joke or a scary movie, your vmPFC stores how that made you feel, happy, scared, excited, so next time you see a similar joke or movie, it helps you know what to expect.

It’s like having a little notebook where you write down how things make you feel, and every time something new happens, you look at your notes to help you decide what's worth doing again.
