Hvordan kan en matematisk algoritme være indkodet i mønsteret for affyring af neuroner med dopamin?
I samarbejde med ZBC Selandia og Aarhus Universitet livestreamer vi dette foredrag om hjernens dopamin.
Foredraget er på engelsk og alle er velkomne.
Professor Ray Dolan er den seneste modtager af "The Brain Prize", som er en pris indenfor forskning om hjernen.
Content of the lecture:
A fundamental requirement for the survival of most living organisms is that they have an ability to effectively seek out sources of reward and avoid sources of punishment. Rewards include food, water, sex, drugs as well as more abstract entities such as money and aesthetic experience. Evolution has endowed humans, and other species, with special mechanisms that promote learning about sources of rewards, as well as providing a motivation to seek out such rewards. The action of a special brain chemical, known as dopamine, is key to these mechanisms. Over the past two decades scientists have made fundamental discoveries that shed new light on how dopamine enables a wide range of reward related behaviours. These discoveries include revealing a fundamental mathematical algorithm that is coded in the pattern of firing of dopamine neurons. Ray Dolan will provide an account of these discoveries, including how they are shaping our current understanding of how humans make choices and the consequences of a loss of brain dopamine for mental function and mental health.
