0:00.0 | There's a very famous experiment in which rats were engineered to have no dopamine, |
0:04.8 | and the scientists discovered that if they put food in the rat's mouth, the rat would eat. |
0:08.7 | But if you put the food even a body length away, the rat will starve to death. |
0:12.4 | Which tells us that dopamine is fundamental to get the things that we need for our basic survival. |
0:18.2 | Now, every time we're doing something that's pleasurable, from sugar to |
0:21.6 | video games, work, pornography, social media, that will affect dopamine. And the more dopamine that's |
0:26.5 | released, the more likely that drug or behavior is to be addictive. But also, the genetic risk of |
0:31.6 | addiction is about 50 to 60 percent. So if you have a biological parent or grandparent with addiction, |
0:37.1 | you are more likely to develop that addiction. |
0:39.7 | We have to keep it in balance in order to stay healthy. |
0:42.6 | Dr. Anna Lemke is Professor of Psychiatry at Stanford, chief of the Stanford Addiction Clinic. |
0:46.8 | And a world leading expert on the subject of dopamine. |
0:49.4 | She will tell you how this one powerful chemical is controlling your life and what to do about it. |
0:53.4 | One of the most important findings in neuroscience in the past 75 years is that the same parts |
0:58.3 | of the brain that process pleasure also process pain. And the balance wants to remain |
1:02.6 | a level. The problem is that we automatically seek out pleasure and avoid pain and we're exposed |
1:07.4 | to all kinds of pleasures that we have in the modern world. And our brains are reeling in response |
1:11.7 | to try to compensate. |
1:12.8 | Now I need more of my drug |
1:13.9 | and more potent forms to get the same effect, |
1:16.0 | which then leads to addiction. |
1:17.3 | And that's what happened to me |
