Andrew Huberman, Ph.D., with Read Montague, Ph.D., on Dopamine, Serotonin & Why Motivation Isn’t About “Hits”

👉 This article is based on a deep, wide-ranging conversation between Andrew Huberman and neuroscientist Read Montague. If you want the full context, stories, and science straight from the source, you can watch the full YouTube episode here.

Who’s in the Conversation

Andrew Huberman, Ph.D. is a neuroscientist and professor at Stanford School of Medicine, known for translating cutting-edge brain science into practical tools for everyday life through the Huberman Lab podcast.

Read Montague, Ph.D. is the Director of the Center for Human Neuroscience Research at Virginia Tech and a pioneer in measuring dopamine and serotonin in real time in living humans. His work helped connect how the brain learns with the same algorithms now used in artificial intelligence.

The Big Idea (Most People Get This Wrong)

Dopamine is not the “pleasure chemical.”

And motivation is not about chasing dopamine “hits.”

According to Montague, dopamine is better understood as a learning signal—a biological currency your brain uses to constantly update expectations about what to do next. It helps you answer questions like:

• Is this worth continuing?

• Should I change direction?

• Am I getting closer to something valuable—or not?

This single insight flips how we think about motivation, habits, social media, relationships, work, and even burnout.

What Dopamine Actually Does

1. Dopamine tracks progress, not rewards

Your brain isn’t waiting for the final outcome (the promotion, the relationship, the success). Dopamine fluctuates as your expectations change step by step.

That means:

• Small signals of progress matter more than big wins

• Long stretches of “nothing happening” are still teaching your brain

• Sudden rewards without effort can confuse the system

This is why chasing instant gratification often kills motivation instead of boosting it.

2. Your brain is always “foraging”

Montague compares humans to animals searching for food. You’re constantly moving through options—dating, careers, scrolling, learning—updating expectations along the way.

There are two modes:

• Explorer mode (novelty, curiosity, distraction)

• Exploitation mode (focus, persistence, execution)

Healthy motivation requires both. Social media and fast feedback push us toward nonstop exploration, which can quietly erode the ability to stay focused long enough to benefit from effort.

3. Serotonin isn’t “happiness”—it’s about waiting and restraint

Serotonin often works opposite dopamine:

• Dopamine rises when things look promising

• Serotonin rises when it’s better to pause, wait, or avoid a negative outcome

This opponent relationship helps your brain balance go vs. hold back. It also explains why some antidepressants (SSRIs) can reduce emotional intensity or blunt motivation in certain people—serotonin can dampen dopamine’s rewarding effects when the systems overlap.

The Surprising Insight Almost No One Talks About

Motivation is shaped more by expectations than outcomes

If your brain expects:

• Constant stimulation → real life feels dull

• Immediate payoff → effort feels pointless

• Endless novelty → persistence feels unbearable

This is why:

• Social media can make focused work harder

• High dopamine environments reset your baseline

• Burnout isn’t always about stress—it’s about distorted expectations

ACTIONABLE TAKEAWAYS (What to Do Differently)

✅ 1. Stop chasing “dopamine hits”

Instead, design your days around visible progress:

• Break big goals into short feedback loops

• Track effort, not just outcomes

• Celebrate movement, not just success

✅ 2. Create friction on purpose

Effort slows learning in a good way. Reading, writing, training, and thinking deeply all force your brain to update expectations more accurately.

Try:

• Longer-form content over short clips

• Fewer apps, more deliberate sessions

• Putting your phone in another room when focusing

✅ 3. Protect your baseline dopamine

Overstimulating your brain (constant novelty, sugar, scrolling, substances) raises the bar so high that normal life stops feeling rewarding.

Practical moves:

• Eat before making important decisions (hunger changes dopamine signaling)

• Don’t stack multiple high-dopamine activities back-to-back

• Get sleep—dopamine systems reset during rest

✅ 4. Learn to enjoy the process, not the payoff

The healthiest motivation comes when your brain learns that effort itself predicts value.

This is why:

• Sports teach resilience

• Difficult skills build confidence

• Consistency beats intensity

Your brain wants forward motion—not perfection.

One Line to Remember

Dopamine isn’t the reward. It’s the signal that teaches you whether continuing is worth it.
