- Motivational state modulates the hedonic value of food images differently in men and womenLuke E Stoeckel
Department of Psychology, University of Alabama at Birmingham, Birmingham, 415 Campbell Hall, 1530 3rd Avenue South AL 35294 1170, USA
Appetite 48:139-44. 2007..No evidence was found of hunger- or fasting-induced enhancement of hedonic ratings of non-foods in women or men, indicating the specificity of the alliesthesia effect for the food images only...
- Peptide YY levels are associated with appetite suppression in response to long-chain fatty acidsLuke E Stoeckel
Department of Psychology, 415 Campbell Hall, 1530 3rd Avenue South, University of Alabama at Birmingham, Birmingham, AL 35294, USA
Physiol Behav 93:289-95. 2008..The close temporal correspondence between these variables supports the proposed role of this peptide in the intermediate-term control of intake, possibly acting to regulate appetite during the intermeal interval...
- Widespread reward-system activation in obese women in response to pictures of high-calorie foodsLuke E Stoeckel
Department of Psychology, University of Alabama at Birmingham, Birmingham, AL 35294 1170, USA
Neuroimage 41:636-47. 2008..In summary, compared to normal-weight controls, obese women exhibited greater activation in response to pictures of high-calorie foods in a large number of regions hypothesized to mediate motivational effects of food cues...
- Effective connectivity of a reward network in obese womenLuke E Stoeckel
Department of Psychology, University of Alabama at Birmingham, Birmingham, AL, USA
Brain Res Bull 79:388-95. 2009..Thus, it is possible that not only greater activation of the reward system, but also differences in the interaction of regions in this network may contribute to the relatively increased motivational value of foods in obese individuals...
- fMRI reactivity on a delay discounting task predicts weight gain in obese womenFelix I Kishinevsky
Department of Psychology, 415 Campbell Hall, 1530 3rd Avenue South, University of Alabama at Birmingham UAB, Birmingham, AL 35294 1170, USA
Appetite 58:582-92. 2012..easy DD trials predicted a greater rate of weight gain over the subsequent 1.3-2.9 years. These results suggest that suboptimal functioning of executive function areas such as prefrontal cortex contributes to the progression of obesity...
- Greater impulsivity is associated with decreased brain activation in obese women during a delay discounting taskLuke E Stoeckel
Department of Psychology, University of Alabama at Birmingham UAB, CH 415, 1720 2nd Avenue South, Birmingham, AL, 35294 1170, USA
Brain Imaging Behav 7:116-28. 2013..These results support the suggestion that increased impulsivity is associated with deficient functioning of executive function areas of the brain...
- Assessments of function and biochemistry of the anterior cingulate cortex in schizophreniaMeredith A Reid
Department of Psychiatry and Behavioral Neurobiology, University of Alabama, Birmingham, Alabama 35294 0017, USA
Biol Psychiatry 68:625-33. 2010..In this study, we sought to clarify the nature of this abnormality by combining proton magnetic resonance spectroscopy (1H-MRS) with functional magnetic resonance imaging (fMRI) at 3T...
- Smaller regional gray matter volume in homeless african american cocaine-dependent men: a preliminary reportRosalyn E Weller
Department of Psychology, University of Alabama at Birmingham UAB, Birmingham, AL, London
Open Neuroimag J 5:57-64. 2011..Reduced gray matter in executive function/inhibitory control regions of the brain in cocaine-dependent individuals may be a preexisting risk factor for the development of addiction and/or a consequence of drug abuse...
- Varenicline as a smoking cessation aid in schizophrenia: effects on smoking behavior and reward sensitivitySunny J Dutra
Department of Psychology, Yale University, P O Box 208205, New Haven, CT 06520, USA
Psychopharmacology (Berl) 219:25-34. 2012..To maximize treatment efficacy while minimizing risks, it is critical to identify reliable predictors of positive response to varenicline in smokers with schizophrenia...
