Xie, C., Jia, T., Rolls, E. T., Robbins, T. W., Sahakian, B. J., Zhang, J., …Zhang, Y. (2021). Reward Versus Nonreward Sensitivity of the Medial Versus Lateral Orbitofrontal Cortex Relates to the Severity of Depressive Symptoms. Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, 6(3), 259-269. https://doi.org/10.1016/j.bpsc.2020.08.017

Background
The orbitofrontal cortex (OFC) is implicated in depression. The hypothesis investigated was whether the OFC sensitivity to reward and nonreward is related to the severity of depressive symptoms.

Methods
Activations in the monetary inc... Read More about Reward Versus Nonreward Sensitivity of the Medial Versus Lateral Orbitofrontal Cortex Relates to the Severity of Depressive Symptoms.

Processing Apples to Puree or Juice Speeds Gastric Emptying and Reduces Postprandial Intestinal Volumes and Satiety in Healthy Adults (2020)

Processing Apples to Puree or Juice Speeds Gastric Emptying and Reduces Postprandial Intestinal Volumes and Satiety in Healthy Adults. Journal of Nutrition, 150(11), 2890-2899. https://doi.org/10.1093/jn/nxaa191

Background: Whole apples produce greater satiety than processed apples, but the underlying mechanisms remain unclear.
Objective: Our aim was to assess the intragastric processing of apple preparations and the associated small and large bowel conten... Read More about Processing Apples to Puree or Juice Speeds Gastric Emptying and Reduces Postprandial Intestinal Volumes and Satiety in Healthy Adults.

The MRI colonic function test: Reproducibility of the Macrogol stimulus challenge (2020)
Journal Article
Wilkinson-Smith, V., Menys, A., Bradley, C., Corsetti, M., Marciani, L., Atkinson, D., …Hoad, C. (2020). The MRI colonic function test: Reproducibility of the Macrogol stimulus challenge. Neurogastroenterology and Motility, 32(11), Article e13942. https://doi.org/10.1111/nmo.13942

Background

Magnetic resonance imaging (MRI) of the colonic response to a macrogol challenge drink can be used to assess the mechanisms underlying severe constipation. We measured the intra-subject reproducibility of MRI measures of colonic funct... Read More about The MRI colonic function test: Reproducibility of the Macrogol stimulus challenge.

Neural correlates of the dual pathway model for attention-deficit/hyperactivity disorder in adolescents (2020)
Journal Article
Shen, C., Luo, Q., Jia, T., Zhao, Q., Desrivières, S., Quinlan, E., …Sahakian, B. J. (2020). Neural correlates of the dual pathway model for attention-deficit/hyperactivity disorder in adolescents. American Journal of Psychiatry, 177(9), 844-854. https://doi.org/10.1176/appi.ajp.2020.19020183

Objective:

The dual-pathway model has been proposed to explain the heterogeneity in symptoms of attention deficit hyperactivity disorder (ADHD) by two independent psychological pathways based on distinct brain circuits. The authors sought to test... Read More about Neural correlates of the dual pathway model for attention-deficit/hyperactivity disorder in adolescents.

Neurobehavioural characterisation and stratification of reinforcement-related behaviour (2020)
Journal Article
Jia, T., Ing, A., Burke Quinlan, E., Tay, N., Luo, Q., Francesca, B., …Schumann, G. (2020). Neurobehavioural characterisation and stratification of reinforcement-related behaviour. Nature Human Behaviour, 4, 544–558. https://doi.org/10.1038/s41562-020-0846-5

Reinforcement-related cognitive processes, such as reward processing, inhibitory control and social-emotional regulation are critical components of externalising and internalising behaviours. It is unclear to what extent the deficit in each of these... Read More about Neurobehavioural characterisation and stratification of reinforcement-related behaviour.
