The Teen Brain Is Wired to Respond to Rewards — Intensely

Dr. Adriana Galván's research at UCLA looked at what happens inside the brain when people receive something rewarding. Using functional MRI scans, her team measured brain activity in children, teenagers, and adults when they received simple rewards like sugar water and money.

The results were striking. In every experiment, the teenage brain's striatum — the key component of the brain's reward system — responded far more intensely than in both children and adults. Not just a little more. Noticeably more.

This tells us something important: there's a sharp increase in reward sensitivity from childhood into adolescence, followed by a sharp decrease into adulthood. The teenage years are a uniquely sensitive window.

Why the Prefrontal Cortex Matters Too

At the same time the reward center is firing at full intensity, the prefrontal cortex — the part of the brain responsible for thinking through consequences, regulating emotions, and managing impulses — is still developing. It doesn't fully mature until the mid-20s.

This is why teens can seem impulsive, moody, or like they're changing their mind every few minutes. As Dr. Lee often explains to families she works with, for teens navigating FND, this combination can feel especially confusing. Parents often ask whether their teen's behavior is "a teenage thing" or "an FND thing." What we often see is that it's both — the developing brain and the nervous system dysregulation of FND are layered on top of each other.

Rather than trying to separate the two, it's more helpful to focus on what to do with that understanding.

It's Not About the Size of the Reward — It's About Ownership

One of the most powerful findings from Dr. Galván's research is that the magnitude of the reward isn't what drives the strongest brain response. What matters is whether the reward is meaningful to the teen.

This is the part most parents never hear. A reward doesn't have to be expensive or material. What activates the striatum is the meaning associated with it — and meaning comes from ownership. Quality time with a parent, the power to choose what the family does on a Saturday evening, getting to stay up a little later — these can all be deeply rewarding when the teen had a hand in choosing them.

The Real Difference Between a Reward and a Bribe

This distinction is neurologically significant, not just semantic.

A bribe is reactive. It's something offered in the heat of the moment to stop a behavior that feels hard to tolerate — a meltdown, an emotional escalation. The message the brain encodes is: escalation gets results.

A reward is different. It's tied to a goal the teen helped set ahead of time. Maybe it's following through on a regulation practice, or completing a step in their recovery plan. The teen had skin in the game before the moment arrived.

The key variables are timing and ownership. Bribes are parent-imposed and reactive. Rewards are team-built and planned.

How to Build a Reward System That Actually Works

Families Dr. Lee works with inside Teen FND Academy learn to build reward systems grounded in this neuroscience. Here's what that process looks like in practice:

Let your teen build their own reward list. Not what you think is good for them — what they actually want. Even if the list looks unrealistic at first, resist the urge to shut it down.

Instead of saying, "There's no way we can do that," the response shifts to something like, "Wow, you have a lot of things you're interested in. Let's figure out how we can make some of these work."

Your role is to set the parameters — budget, timeline, what's realistic — while your teen maintains ownership of what they're working toward. Bigger rewards simply require more sustained effort and more points. You're not denying what they want. You're building the system together.

This approach is what makes it different from bribery. Even if money is part of the equation on the surface, the ownership and responsibility belong to the teen. And according to the research, that ownership is exactly what makes the brain respond.

Why This Matters for FND Recovery

This process is built to support more than just behavior change. When teens feel ownership over their goals and rewards, they're practicing agency and self-efficacy — two things that are essential for nervous system regulation.

What families often see is that this kind of structured, collaborative system reduces the need for micromanaging. Teens don't feel controlled, and parents don't feel like they're constantly negotiating in crisis moments. Both sides feel more prepared.

If you're looking for a structured approach to building these kinds of systems — one that supports your teen's recovery and your family's well-being — visit teenfndacademy.com to learn how Teen FND Academy is helping families move forward.
