0:00.0 | Welcome to Huberman Lab Essentials, where we revisit past episodes for the most potent and actionable |
0:05.8 | science-based tools for mental health, physical health, and performance. |
0:11.4 | And now for my discussion with Dr. Anna Lemke. |
0:15.7 | I and many listeners of this podcast are obsessed with dopamine. What is dopamine? And what are maybe some |
0:25.3 | things about dopamine that most people don't know? And probably that I don't know either. |
0:30.5 | So dopamine is a neurotransmitter. And neurotransmitters are those molecules that bridge the gap between |
0:37.0 | two neurons. So they essentially |
0:39.3 | allow one neuron, the presynaptic neuron, to communicate with the post-synaptic neuron. |
0:45.4 | Dopamine is intimately associated with the experience of reward, but also with movement, |
0:52.8 | which I think is really interesting because movement |
0:54.9 | and reward are linked, right? If you think about, you know, early humans, you had to move |
1:02.0 | in order to go seek out the water or the meat or whatever it was. So dopamine is this really |
1:09.2 | powerful, important molecule in the brain that helps us experience pleasure. |
1:17.7 | It's not the only neurotransmitter involved in pleasure, but it's a really, really important one. |
1:22.8 | And if you want to think about something that most people don't know about dopamine, which I think |
1:28.2 | is really interesting, is that we are always releasing dopamine at a kind of tonic baseline rate, |
1:34.9 | and it's really the deviation from that baseline rather than like hits of dopamine in a vacuum |
1:41.2 | that make a difference. So when we experience pleasure, our dopamine release goes above baseline. |
1:47.4 | And likewise, dopamine can go below that tonic baseline. |
1:51.0 | And then we experience a kind of pain. |
1:54.4 | Interesting. |
1:55.0 | So is it fair to say that one's baseline levels of dopamine, |
