Nudge-it talks by Prof Gareth Leng

Gareth in Turkey

 

In June, Gareth gave a plenary lecture at the annual meeting of the Turkish Neuroscience Society at Sakarya entitled “Oxytocin – the sweet hormone?” – the topic of his recent review, published in Trends in Endocrinology and Metabolism. He went on to give a public lecture at Yeditipe University in Istanbul on “The Loving Brain” covering the various behavioral effects of oxytocin.

In January he gave a lecture to The Royal Society of Medicine in London on “The determinants of food choice.”

Prof Suzanne Dickson meets the scientist who discovered Ghrelin

A photo  opportunity for Nudge-it researcher, Suzanne Dickson, with Professor Kenji Kangawa, who discovered the appetite-promoting hormone, ghrelin. Suzanne gave a keynote lecture on her recent work with ghrelin at the International Symposium on Ghrelin and Energy Metabolism Homeostasis, held in Kyoto.  The Nudge-it project is about dietary choice and Suzanne's team have recently shown that ghrelin guides dietary choice, both in normal rats and in rats binging on a high fat diet.  Given that ghrelin promotes reward behaviours for food, we had expected to find that ghrelin increases intake of sugar and fat.  What we found is that rats injected with ghrelin start to eat more of their regular chow, arguably a “healthier option”.  

Prof Kangawa and his team are continuing to pursue clinical applications of ghrelin, especially for promoting food intake in cachectic patients.  Cachexia is a multi-factorial syndrome defined by an ongoing loss of skeletal muscle mass (with or without loss of fat mass) that cannot be reversed by conventional nutritional support and leads to progressive functional impairment. Therefore this new information from Nudge-it is important and relevant for dietary choice behaviour in such patient groups.A photo  opportunity for Nudge-it researcher, Suzanne Dickson, with Professor Kenji Kangawa, who discovered the appetite-promoting hormone, ghrelin.

Roger at ECNP

 

Nudge-it researcher, Prof Roger Adan and his group recently presented data from the project at the ECNP Workshop in Nice.  This meeting, sponsored by the European College for Neuropsychopharmacology invites around 100 young scientists each year, selected from quality of their submitted abstracts. The group includes psychiatrists, neuroscientists, psychologists, neurologists and those interested in drug development for brain diseases.    In his presentation he illustrated technologies to remotely active dopamine neurons using the drug CNO (chemogenetics) and recording from dopamine neurons using fiber photometry and small animal neuroimaging.  Additionally three of his PhD students presented data, orally and as posters

ECNP are committed to supporting nutrition and brain health and have recently supported the establishment of a nutrition network for which Suzanne L Dickson and Roger Adan are Chair and Co-chair respectively.  

The large ECNP annual meeting this year will be held in Paris (2-5 September 2017).  See http://2017.ecnp.eu

BBC iWonder - What's making me eat too much?

The article, made in conjunction  with Professor Jeff Brunstrom and the team at the University of Bristol, explores how decisions on how much we eat are governed by many subtle  influences.
