New Publication in Frontiers in Human Neuroscience

The MIRAGE lab is pleased to announce another publication using the MIRAGE system. The research article is called, "Spatial compression impairs prism-adaptation in healthy individuals" (link) and uses MIRAGE to compress the visual workspace in order to model Neglect prism adaptation performance and is published in the Journal Frontiers in Human Neuroscience.

Neglect is a disorder that can occur following brain injury, which causes the patient to have reduced awareness of the left side of space.

This is a picture drawn by a patient suffering from Neglect. You can see that when drawing the house he misses out the left side of the chimney, the door and each of the windows as well as the left side of the left tree.

Wearing rightward optical prisms over your eyes makes everything appear to be to the right of where it really is. When you try to reach and touch something you miss to the right. After a while you get used to the prisms and can reach accurately again (adaptation), but if you take them off you suddenly start missing to the left for a while (the aftereffect). The processes of adaptation and the aftereffect can help to reduce visual neglect. Neglect patients do not adapt to prisms in the same way as healthy people. This may be due to an abnormal compression of their visual workspace.

Research of this kind can help us to further understand changes in the brain that cause the disorder and also help understand mechanisms underlying temporary restoration of awareness following prism adaptation.

A trip to London for the Big Bang Fair 2013

Below is a short post written by one of the student volunteers who helped out at the Big Bang Fair. It is a nice example of how working with MIRAGE can be fun, not just for those experiencing the strange illusions, but also for those delivering them:

Last March Roger Newport took us four lucky 2^nd year Psychology students to London to represent the Psychology Department of the University of Nottingham and the British Psychological Society at the Big Bang Fair 2013. The Big Bang Fair celebrates science by aiming to reach out to and spark interest for science in school children of any age and year. High-profile firms, such as “e.on” and “l’oreal”, university departments and our lovely little, but hugely successful BPS stall provided interactive demonstrations of experiments throughout the whole day over an extended weekend.

Roger Newport introduced his invention, the MIRAGE box, to the fair and we four 2^nd years were trained to demonstrate and explain bodily illusions with the help of the machine. While the machines were visually seamless compared to the flashing lights and bright colours other stalls had to offer, our stall increased in popularity solely by word of mouth that the bodily illusions that we demonstrated were “creepy”, “weird” and simply “amazing”. The simple finger stretching illusion, in which a person sees an image in the box of his finger being stretched, while we simultaneously pull at the finger, results in an actual feeling of a stretched finger. Even though one knows that one’s finger is not actually being stretched, one’s brain is fooled into sensing the stretch every single time. While this demonstrated a fun side to psychology, which also reached out to the younger children, we could address the older ones by explaining that this is an example of how our brain’s representation of the body is simply made up of what we see and feel and that, on a more serious note, the finger stretching illusion has been found to temporarily reduce or eliminate pain in patients with arthritis.

It was most rewarding to see the amazement in the children’s eyes and observe them trying to peak into the box to see whether their finger actually had been stretched. Additionally, it was a wonderful experience to be able to share our passion for psychology with the university students of tomorrow, especially sparking interest in those young eager minds to whom psychology was something completely new.

It was an experience, I would not have wanted to miss and a huge thank you has to go to all involved in making this an incredible experience, but especially to Roger Newport for giving us this opportunity and trusting us to adequately represent his invention.

MIRAGE at the Big Bang Fair

The Big Bang Fair is an annual event aimed at engaging young people in science and technology. The fair is open to primary school children from across the UK and this year it was held at the Excel Arena in London between March 14th - 16th. The MIRAGE lab were there to join in the fun!

It was a huge success and even with two MIRAGE systems it was difficult to keep up with demand. Over the course of the fair the team were visited by thousands of children, parents and teachers as well as other exhibitors who also wanted their finger stretched!

New Illusion

Haika was the guinea pig for our latest bit of fun research, although you see from the way her expression changes at the end of the video that she didn't find it all quite as much fun as we did. You'll have to forgive the shaky hand on the camera, but Tasha couldn't stop laughing while filming. We'll explain more about the illusion another time, but it's all part of the grand plan to work out exactly what we can do to change and mould body representations.

The new MIRAGE100 goes to the Netherlands

This is Haika from Utrecht. She and Alyanne visited the lab in Nottingham to get some training and to pick up their new system, the MIRAGE100 - faster than before with only a 10ms delay between image capture and display. They loved all the illusions and even came up with a couple of their own. Next week we'll post a video of Haika's reaction to one of our latest creations.

World Arthritis Day 2012

Today, Friday 12 October, is World Arthritis Day. The event is designed to raise awareness of rheumatic and musculoskeletal diseases. Millions of people around the world suffer from such diseases, so events like this are really important. Hopefully research into chronic pain conditions such as arthritis will continue to make progress to help improve treatment and pain management.

Congratulations Dr. Kirsten McKenzie

We would like to congratulate Dr. Kirsten McKenzie (MIRAGE lab Malayisa Campus) and husband Richard Fender on the birth of their baby boy. Rylan James McKenzie Fender was born in Malaysia just three weeks ago. He is doing really well, is incredibly cute, and surely a cognitive neuroscientist in the making?
