The Dimensionality Reduction and Population Dynamics in Neural Data conference were held at Nordita in Stockholm 11-14 February 2020. Most parts of the conference were recorded (see links below).

About the conference

The brain represents and processes information through the activity of many neurons whose firing patterns are correlated with each other in non-trivial ways. These correlations, in general, imply that the activity of a population of neurons involved in a task has a lower dimensional representation. Naturally, then, discovering and understanding such representations are important steps in understanding the operations of the nervous system, and theoretical and experimental neuroscientists have been making interesting progress on this subject. The aim of this conference is to gather together a number of key players in the effort for developing methods for dimensionality reduction in neural data and studying the population dynamics of networks of neurons from this angle. We aim to review the current approaches to the problem, identify the major questions that need to be addressed in the future, and discuss how we should move forward with those questions.

Selected media

Selected media

The scientists at the Kavli Institute take part in various activities for communicating science to the public. The tools of the trade for communicating within the science community, like peer-reviewed journals and conference proceedings, are not good sources of knowledge for the public. Rather it’s through popular media, like online video platforms, television, social media, radio, podcasts, newspapers and magazines, as well as popularized talks and debates taking place in the public, that the majority of citizens gain knowledge and advice about science. 

Popular science communication demands a translation of both complexity, language and dissemination form, without compromising central scientific aspects. By explaining scientific relationships in a straight-forward language and contextualizing scientific facts within issues of public interest and concern, our scientists aim at not only translating information and facts into publicly accessible knowledge and understanding, but also at providing a vocabulary that allows the broader public to engage in and join discourses about local and global issues that involve both risks and benefits, and in which every citizen is a stakeholder. 

These insights represent the fundament for the institute's public outreach activities and science communication plan.

Starmus represents an innovative approach to boosting public understanding of science, inviting citizens to engage with and participate in scientific discourses, by bringing together the very best of science and art into a weeklong popular science dissemination festival. The festival is pulling thousands of visitors, and is covered by major media houses across the world.


In 2016 Edvard Moser participated in the Starmus festival III held in Tenerife, with a popular science lecture on grid cells. Edvard and May-Britt Moser have since been instrumental in bringing the Starmus initiative to Trondheim (2017).
