A wall covered in densely spread Nutella and a video of a woman eating a whole raw onion are among a number of installations on show at a new exhibition in Cork exploring the feelings we have about food.

Gut Instinct at the Glucksman gallery in UCC utilises research from the APC Microbiome Institute at the university to shine a light on how the state of the bugs in our gut can influence our state of mind.

Among the exhibits is the film 'The Onion'.

During it, artist Marina Abramovic eats a raw onion while her voice-over repeats a series of complaints, offering an unflinching portrayal of her discomfort and disgust.

'Untitled' is Thomas Rentmeister's painted wall of Nutella chocolate spread, which depicts the sheer amount of inedible sweetness both enticing and revolting that we encounter in our lives.

Siobhan McGibbon's sculptures see white legs emerge from enlarged organs while her drawings depict microbes fusing with simplified human forms.

Strange sounding and often disgusting recipes are also featured in the 'Domestic Godless' exhibit, in an attempt to make people thing about the notions of disgust and digestion.

Neil Shawcross' paintings of items including tins of soup and bottles of ketchup delves into the emotional attachments we have for particular brands and comfort foods.

"In Neuroscience and Medicine, we're conditioned to think of only what is happening above the neck in terms of the regulation of our emotions," said John Cryan, Professor and Chair, Anatomy and Neuroscience, UCC.

"This is changing. Ground-breaking research, including that being carried out in the APC Microbiome Institute in UCC, is literally turning this concept upside down."

"A painting made of Nutella might seem like strange thing to hang in an art gallery, but artists respond instinctively to the world around them and the exhibition Gut Instinct brings together artworks that give tasty, if unusual, form to the ground-breaking ideas of John Cryan and his colleagues at APC," said Fiona Kearney, director of the gallery.

The exhibition opens today and runs until 19 March.
