The Glymphatic System

WHY DO WE NEED TO SLEEP?

There are many good answers to this question, but one of them is – we need brain wash!

This is taken care of by the GLYMPHATIC system, an amazing system that – during sleep (especially deep sleep) – helps the brain to get rid of cellular waste, that could otherwise clot up the brain and ultimately lead to dementia (e.g. Alzheimers disease).

The brain is a very dense network of both neurons (nerve cells) and glia cells (support cells). During wakefulness, cellular waste builds up, just like when our daily activities generate waste. However, the activity is too high – and the space too limited – to wash away the waste. When we fall asleep, nerve cells change their activity and the support cells named astrocytes shrink in size and leave more space. This opens up for fluid coming from the so-called perivascular space (described in film), which then can flow into the cell-dense areas. The flow goes from arteries to veins and washes out cellular waste products so that we can wake up refreshed and ready for new activities.

An analogy could be garbage trucks, that cannot work during the day because of heavy traffic and activity. But at nigth, the activity and traffic ceases and waste can be picked up and removed.

The system was described and named by the Danish scientist Maiken Nedergaard in 2013 (watch a full talk with her from the Europhysiology conference in 2018, describing the system in detail here: https://youtu.be/He6HMnMbxAc).

Pulmonar alveoli animation

alveoli scientic illustration 3D render

I am currently working on an animation about air pollution for Aarhus University. In that project, I have modelled the alveoli, which is the place for exchange of gases (oxygen, carbondioxide) between the exterior and the blood. Unoxygenized blood arrives from the heart, pass by the capillary network surrounding the alvoli sacs (the wall of which is only one cell layer thick) where it is oxygenized and releases its carbondioxide. Then it runs back to the heart, from where it is pumped out into the entire body.

My animation about EEG was used in research paper

Posted on

I have produced an animated film for a research team at Lundbeck. It describes the methodology of EEG (electroencephalography) in rodents, used to study the effects of neuropharmacological compounds.

The research was published in a research paper in Frontiers in psychiatry by Christien Bowman and Kjartan Herrik, where my animation (in three parts) can be found in the supplementary materials.

I am very proud when my work is used to increase scientific insight.

Use of my animation about ground water pollution

Posted on

Last year, I made an animation about ground water pollution and its impact on human health – for Torben Sigsgaard at Aarhus University. Read his tweet about it here:

Omicron variant of concern in Europe

Posted on

This animated data-visualization shows the shift from delta (blue) to omicron (red) variant of concern of coronavirus in the EU / EØS countries of Europe. The incidence in the different countries are shown as height. All data are from European Centre for Disease Prevention and Control (https://www.ecdc.europa.eu/en/news-events/weekly-epidemiological-update-omicron-variant-concern-voc-week-2-data-13-january-2022).

Happy New Year 2022

Posted on

It’s the end of 2021 – and the beginning of 2022. I hope for a great year – hopefully without too much COVID-19 and with new and better solutions for great challenges like the climate changes.

With this image of a crack in the ice (on the lake close to my Swedish summerhouse) that really looked like a neuron, I wish all my customers, collaboration partners and other people, that has helped or inspired me during the last year, a happy new year!

It has been a good year for Moving Science. I have had really intersting animation, illustration and visualization projects to work on. The subjects have been many: neuroscience, protein chemistry, neuropharmacology, ground water quality, climate changes, electroencephalography, herd immunity, cancer immunotherapy, vaccinology and more.

And I have also found time (in between customer projects) to work on some own projects; a series about Scandinavian Women in Science from the 20th Century, python scripting and data-visualization, 3D-modelling as well as digital drawing and painting.

I really just love what I do!
