Journal ArticleDOI
A link between FTO, ghrelin, and impaired brain food-cue responsivity
Efthimia Karra,Owen O'Daly,Agharul I. Choudhury,Ahmed Yousseif,Steven Millership,Marianne T. Neary,William R. Scott,Keval Chandarana,Sean Manning,Martin E. Hess,Hiroshi Iwakura,Takashi Akamizu,Queensta Millet,Cigdem Gelegen,Megan E. Drew,Sofia Rahman,Julian J. Emmanuel,Steven Williams,Ulrich Rüther,Jens C. Brüning,Dominic J. Withers,Fernando Zelaya,Rachel L. Batterham +22 more
TL;DR: Functional MRI in normal-weight AA and TT humans found that the FTO genotype modulates the neural responses to food images in homeostatic and brain reward regions, and shows that FTO regulates ghrelin, a key mediator of ingestive behavior.
Journal ArticleDOI
A diffusion tensor imaging study of fasciculi in schizophrenia.
Sukhwinder S. Shergill,Richard A A Kanaan,Xavier Chitnis,Owen O'Daly,Derek K. Jones,Sophia Frangou,Seren C. K. Williams,Robert Howard,Gareth J. Barker,Robin M. Murray,Philip McGuire +10 more
TL;DR: Within the patient group, the propensity to experience auditory hallucinations was associated with relatively increased fractional anisotropy in superior longitudinal fasciculi and in the anterior cingulum, whereas within the healthy comparison subjects, this was not the case.
Journal ArticleDOI
Acute sleep deprivation enhances the brain's response to hedonic food stimuli: an fMRI study.
Christian Benedict,Samantha J. Brooks,Owen O'Daly,Markus Sällman Almén,Arvid Morell,Karin Åberg,Malin Gingnell,Bernd Schultes,Manfred Hallschmid,Jan-Erik Broman,Elna-Marie Larsson,Helgi B. Schiöth +11 more
TL;DR: Examination of brain activation after sleep and sleep deprivation in response to images of food provides evidence that acute sleep loss enhances hedonic stimulus processing in the brain underlying the drive to consume food, independent of plasma glucose levels.
Journal ArticleDOI
Decreased activation of lateral orbitofrontal cortex during risky choices under uncertainty is associated with disadvantageous decision-making and suicidal behavior
Fabrice Jollant,Natalia Lawrence,Natalia Lawrence,Emilie Olié,Owen O'Daly,Alain Malafosse,Philippe Courtet,Mary L. Phillips,Mary L. Phillips,Mary L. Phillips +9 more
TL;DR: Altered processing of risk under conditions of uncertainty, associated with left lateral orbitofrontal cortex dysfunction, could explain the decision-making deficits observed in suicide attempters.
Journal ArticleDOI
Distinct Roles of Prefrontal Cortical Subregions in the Iowa Gambling Task
Natalia Lawrence,Natalia Lawrence,Fabrice Jollant,Fabrice Jollant,Owen O'Daly,Fernando Zelaya,Mary L. Phillips,Mary L. Phillips +7 more
TL;DR: A version of the Iowa Gambling Task specifically modified for event-related functional magnetic resonance imaging is developed and validated, revealing that deciding advantageously under initially ambiguous conditions may require both continuous and dynamic processes involving both the ventral and dorsal prefrontal cortex.
