In the dark in an old chemistry laboratory in Bangor, Dr Kurtz invites you to take part in a scientific experiment, but things are not always what they seem...
The scene may sound like it has jumped straight from the pages of an HG Wells novel, but Cerebellium is a curious combination of pioneering neuroscience and immersive theatre.
In this installation in a disused laboratory, the audience is transported, one by one, to a science fiction world filled with sensory illusions. As they explore their perceptions of the world around them, the audience members find themselves to be part of the experiment.

Neuroscience may be an unlikely subject for theatre, but this production throws up some fascinating questions about our views of reality and provides a novel way to discover more about science.
Performer and co-creator Professor Guillaume Thierry said: “Cerebellium is designed as a three-in-one experiment: theatrical, scientific and philosophical.
"The theatrical experiment tests whether it is possible to get involved emotionally and cognitively well beyond what is experienced when you sit in a conventional theatre facing a stage.
"The scientific experiment tests whether people with basic knowledge of the brain and human biology will choose to believe in a radical science fiction scenario.
"The philosophical experiment tests whether the audience becomes more aware of what existence means. How does consciousness relate to existence?"

Cerebellium is the brainchild of the Psychology Department of Bangor University and theatre production companies Pontio and Republic of the Imagination.
Pontio's arts development officer Dyfan Roberts said: "This is theatre like no other - the stage really is your brain.
"Cerebellium will explore optical and cognitive illusions. Audiences should be ready to have their expectations and perceptions challenged, but they will learn something about themselves too along the way."
The production returns for Bangor Science Festival following its sell-out success last year. The week offers a range of events for all ages, from family activities through to exhibitions and lectures.
It is part of the wider National Science and Engineering Week which is designed to broaden access to scientific research, provoke debate and inspire future generations to become scientists.
Cerebellium takes place at the WC Evans Laboratory, Bangor, from 11-16 March. Individual time slots are from 6.30pm-9.30pm. Pre-booking is essential. Tickets are £8 and are available from Pontio and the Wales Millennium Centre.
The minimum age is 16, and under 18s must be in pairs. The performance is not suitable for people of a nervous disposition, or for those with claustrophobia, heart and mobility problems or issues with darkness.
