How 你的 大脑’s Reward 回路 Drive 你的 Choices | Dr. Robert Malenka

这 section of the episode develops the topic 通过 the following source points: 这 transcript version is not in its final form 和 会 be updated. 安德鲁·休伯曼： Welcome to the Huberman Lab 播客, where 我们 discuss science 和 science-based tools 对于 everyday life. [OPENING THEME MUSIC] I'm Andrew Huberman, 和 I'm a professor of 神经生物学 和 Ophthalmology at Stanford School of Medicine. Today, my guest is Dr. Robert Malenka. Dr. Robert Malenka is a professor of Psychiatry 和 Behavioral Sciences at Stanford University School of Medicine. He is both medical doctor, an MD, 和 a researcher, a PhD. His laboratory is famous 对于 having discovered some of the key components allowing neuroplasticity, 那 is, the 神经系统's ability to change in response to experience. In addition, Dr. Malanka's 研究 is considered central to the textbook knowledge 关于 how reward 系统 in the 大脑 are organized 和 function. Indeed, Dr. Melanca's 研究 over the last ten 或 15 years has merged what was once 二 disparate fields, the 首先 being the 研究 of neuroplasticity, again, the 神经系统's ability to change in response to experience, 和 the other field being the field of 多巴胺 as it relates to pleasure 和 addiction. His laboratory has shown, 对于 instance, 那 when 我们 seek out particular forms of pleasure, regardless of whether 或 not they are healthy 对于 us, 那 changes the way 那 我们的 reward circuitry works 和 actually changes the way 那 多巴胺 is 释放了 和 how it impacts the 大脑. 和 his work has also informed how 我们 seek out healthy pleasures, including healthy food 和 social connection. Today's discussion explores all of 这些 topics, 和 by the end of today's discussion, 你 会 have a rich understanding of how 神经化学物质 like 多巴胺 和 serotonin work in parallel, to reinforce 那 is, to 增加 the probability 那 我们 会 engage in certain types of thinking 和 behaviors. So if 你 are somebody interested in neuroplasticity, 那 is, how the 神经系统 可以 change in response to experience 和 或 你 are interested in reward 系统, what motivates us, 和 what 我们 are 可能 to pursue in the future, given 我们的 choices of past, 和 if 你 are interested in things like social connection 和 empathy, 或 lack thereof, today's discussion encompasses all of 那些 topics. It is worth mentioning 那 Dr. Malenka is a true luminary in all of the fields I just mentioned, as well as several other fields. In fact, when 你 look out on the landscape of modern neuroscience, what 你'll discover is 那 a 非常 large percentage of the top laboratories studying neuroplasticity 和 reward 系统 和 so on, all stemmed 从 having trained in Dr. Malenka's laboratory. So it's a real honor 和 pleasure to be able to host him today, 和 I'm sure 那 我们的 discussion is going to greatly enrich the way 那 你 think 关于 大脑 function, neuroplasticity, 和 reward.
