The Truth About Dopamine — wanting, liking, and the practice of savoring

No — and Davidson is unusually direct about it. "Dopamine is essential for human life. There's no turning dopamine off. Anyone who thinks they're going on a dopamine detox and really banishing their brains of dopamine — that would not be compatible with life."

The popular framing of dopamine as a toxin to purge misses what the molecule is actually doing. Dopamine powers motivation, desire, and any goal-directed behavior. Without it, getting out of bed would be difficult. The detox premise has no biological referent.

Like the amygdala before it, dopamine has been collapsed into a villain. The popular story attaches it to doom scrolling, addiction, and distraction — then concludes the molecule itself is the problem.

That framing leads people toward strategies like detoxes and abstinence that don't map to what's actually happening in the brain. The molecule plays both sides of every motivated behavior — the wholesome and the compulsive. The trick is not eliminating it but understanding which side it's on.

When one neuron fires, an electric potential travels down its axon — the wire extending from the cell body. At the end of the axon, a small packet of chemical is released. That packet binds to a receptor on a second neuron and initiates an electric change there.

That chemical handoff is the neurotransmitter. And that handoff, repeated trillions of times a second across the brain, is how neurons communicate.

When you wiggle the big toe on your right foot, you are firing a single neuron that extends all the way from your brain to that toe. One cell. One wire. That distance.

Neurons come in many lengths. The fact that one of them can bridge your spinal column from cortex to extremity is the kind of detail that resets your sense of scale for what is happening inside you.

A neurotransmitter mediates direct neuron-to-neuron communication — one cell sending a signal to the next. A neuromodulator changes the threshold for whether a neuron will fire in the first place. It is the molecular soup the neuron sits in, shifting the conditions under which the next firing happens.

Dopamine acts as both. The same molecule plays two different roles depending on where it is and what it is binding to. This is the first hint that the story of dopamine is going to be a story about location, not just chemistry.

About 85 to 88 billion neurons. Connections among them in the trillions. The number of communications happening right now between your ears is beyond what we can hold in mind.

That density is part of why simple molecule-to-mental-state stories collapse on contact. The substrate is too dense and too interlinked for that level of attribution to be accurate.

Davidson is clear about this: "There's no well-defined psychological state that can be pinned to one specific molecule. It's just much more complicated than that."

The brain runs on hundreds of neurotransmitters and neuromodulators in overlapping roles — many of which have not yet been discovered. Headlines that say "X is the Y molecule" almost always oversimplify a system we are still mapping. The honest claim is that dopamine plays a role, alongside many others.

Some neuroscientists compare EEG — the standard non-invasive method of placing electrodes on the scalp — to putting a stethoscope on the hood of a car and trying to understand how the car works from the sounds.

The tool is useful and has fast time resolution. It is also coarse, given the complexity it is trying to listen to. The methods that would let us look at finer-grained activity in humans non-invasively do not yet exist. At some point in history, Davidson notes, we'll look back at this era and it will seem like the Stone Age.

"Dopamine is really essential in what we can think of as motivation — our desire, our seeking, anything that is goal-directed."

Even pedestrian goals, like deciding what to do after the podcast, involve the dopamine system. It powers an approach-oriented, energetic stance toward whatever is next. The same circuit that drives compulsive scrolling also drives getting out of bed to meditate.

Getting out of bed would be very difficult. Doing anything would be very difficult.

The strong aspiration to meditate, to spring up in the morning, to pursue any goal at all — all of it relies on the dopamine system. The wholesome version of motivation is dopamine, not just the compulsive version. This is the part the detox framing misses: turning the system off would not free you, it would flatten you.

Berridge labeled the key function of the dopamine system as wanting — and contrasted it with liking. The two are often confused but are not the same.

Sometimes we like the things we want. Not always. The wanting circuit can fire independently of the liking circuit, and that gap is where most of the trouble lives.

Perseveration. You keep seeking even when finding does not produce satisfaction. The system keeps firing the "go get more" signal regardless of whether the more is actually rewarding.

This is the engine behind doom scrolling and most compulsive behaviors. Wanting stays loud while liking quietly drops out — and the loop sustains itself on a signal that is no longer pointing anywhere good.

Your brain builds a mental model of what to expect from a stimulus. If the next thing you encounter is better than predicted, you get a larger dopamine spike. If it is comparable, no change. If it is worse, dopamine actually drops below baseline.

The signal is dynamic. It is constantly updating against expectation — and it informs your future seeking. This is the math the algorithm is solving for, even though it doesn't know it is.

Apps optimize for novelty + duration + emotional capture. The algorithm serves you slightly varied content — not pure repetition. Pure repetition would flatten the dopamine signal. Controlled variation keeps the prediction-error system engaged.

The same funny video ten times in a row goes flat. A different funny video each time keeps the spike alive. The platform isn't trying to make you happy — it's trying to keep your prediction error from settling.

Davidson gives it a name: experiential fusion. "Their whole awareness is fused with the activity they're engaged in. There's not a lot of meta-awareness — they're just sucked in."

Conscious, fully-aware doom scrolling tends to stop itself. The compulsive version needs the mindlessness. Some behaviors only work when you are not paying attention. The moment you really savor them, you stop.

Dopamine acts in multiple brain regions — and its function changes depending on where. Same molecule, different receptors, different connections, different consequences.

The wanting circuit, anchored in the ventral striatum, is anatomically distinct from the prediction-error circuit, which runs through the caudate nucleus and prefrontal cortex. One molecule, several jobs.

In animal studies with damage to the ventral striatum, the animal will not seek a reward. It will not walk six feet for its favorite food — even when it can smell it. The seeking is gone.

Put the food in its mouth and it still enjoys it. Same facial expressions. Same sounds. Wanting circuit damaged. Liking circuit intact. Two systems, related but not identical.

Endogenous opioids and endocannabinoids. The brain's internal versions of opiates, and of the active ingredient in marijuana. These are the molecules associated with pleasure itself — with the in-the-mouth enjoyment.

Dopamine drives the seeking. These drive the enjoying. And that is why you can have a brain on fire with wanting that is not actually liking anything it finds.

Don't try to kill the wanting. Build the liking. Create the causes and conditions to really tune in to and appreciate positive moments. Savor them.

This pulls energy out of the seeking loop on its own. You don't need to white-knuckle abstinence — you need a stronger alternative the system can lean toward.

One way to practice mindful breathing treats the breath as a neutral anchor for awareness itself. You step back, orient to awareness, let the breath pass through.

Another way treats the breath as a felt nourishing presence. You immerse yourself in its healing, pleasant quality. Both work — but they train different things. Savoring trains the liking circuit directly.

It is a skill — the way tuning a radio is a skill. You learn to dial in to a state like connection or loving-kindness, and then keep it dialed in while habit energy tries to pull you off course.

Around someone like the Dalai Lama, you can feel it. He is never not in that frequency. The signal is steady because the practice has been long enough that the dial does not drift.

It is depletion without replacement. You remove the stimulus and put nothing in its place. Nothing sustains you. It is not joyful and it is not durable.

People relapse because the underlying hunger is real and was never addressed. The system was looking for something. Taking the something away does not stop the looking.

The standard translation is "renunciation" — which conjures the detox mindset of distancing yourself from the bad stuff. A more accurate translation is "reorientation."

It is about what you are turning toward, not what you are turning away from. The letting-go becomes natural because the alternative is obviously superior. You are not subtracting. You are choosing.

Appreciation and gratitude. Bodhicitta — reflecting on how his actions can be of benefit to others. Leaning into the sweetness of connection rather than chasing it.

And when wanting rises, becoming aware of it directly. Staying with the awareness — without getting sucked in — tends to let it subside on its own. The wanting doesn't need to be defeated. Only seen clearly enough that its pull weakens.
