Investigating the relationships between the immune system and the brain

Using The Observer XT to investigate overt signs of sickness and health communication

Our research group is investigating the relationships between the immune system and the brain in Humans. One of the models we use is the experimentally-induced sickness. In this model, we intravenously inject a component of a bacteria (but not the bacteria itself), which makes the immune system believe that the body is infected and that it needs to fight the infection. Therefore, this injection activates the immune system for a short time (3-4 hours) during which a sickness response is triggered. This sickness response is composed of all symptoms that we may feel when sick, such as fatigue, reduced appetite, difficulties to concentrate, reduced motivation to see people, etc (1).

The effect of simulation-based obstetric team training on patient-reported quality of care

Posted by Guest blogger on Dec 16, 2016

Early September I spent an afternoon in the auditorium of the Technical University Eindhoven, The Netherlands to listen to the PhD defense of Sophie Truijens. As I already announced in the blog about simulation-based training, Sophie will tell us more about her study, and share her insights with us in this blog post.

Students’ first contact with The Observer XT

Posted by Guest blogger on Jul 8, 2016

Systematic behavior research in farm animals has increasingly gained importance, especially during the last years.

Since the intensification of animal husbandry has substantially enhanced the discrepancy between natural and artificial environment, the following questions arise: What are the prerequisites for an animal to be able to show its full range of social behavior? How much space do animals require? What is the optimal group size?

The close monitoring of the social behavior of pigs, cattle, poultry and horses plays a major role in terms of welfare assessment and health research.

How to use CatWalk XT and Incapacitance Tester in non-clinical pain research

Posted by Guest blogger on May 13, 2016

Today we have another guest blog post for you! Heta Svard from Orion Pharma studies pain and neurological disorders and will be presenting a poster on a recent study at Measuring Behavior 2016 in Dublin this month! I encourage you to pay her a visit (poster no. 39), but for now, you can read about her study in this post. Thanks, Heta!

Assessing motor deficits in mice following traumatic brain injury

Posted by Guest blogger on Mar 31, 2016

Half a year ago, I wrote about rats on the CatWalk XT system, and we added a great white paper written by Kristina Ängeby Möller to the collection. Today, I am very excited to tell you that Marcella Cline (University of Washington) and Dr. Donna Cross (University of Utah) are so kind to share their insights on working with mice on the CatWalk XT system in both a blog post and a white paper. Enjoy!

The Zebrafish Multi-Chambered Exploratory Test (ZEMCET)

Today we have another guest writing for us, or actually two. I met Frank Scalzo (Bard College, New York) at last year's annual meeting of the Society for Neuroscience in Chicago and I was very curious to find out more about their research using multi-chambered set-ups for their zebrafish larvae. Frank M. Scalzo and his colleague Brandon Chen were kind enough to share their insights in this blog post. Enjoy!

Measuring flow

Posted by Guest blogger on Mar 15, 2016

By Martijn van den Berg

Flow is a state in which a person is fully involved in an activity, decreasing self-consciousness and sense of time. This process requires a person to be extremely focused, as well as exactly have the skills to master a task. Achieving flow is desirable, because during flow a person can reach maximum skill level as well as creativity within a domain[1]. However, measuring when a person is in flow and subsequently finding out how to get a person in a flow state is difficult, because flow causes persons to decrease self-consciousness, not recalling to what extent flow occurred[2].
