Neural Correlates of Evidence and Urgency During Human Perceptual Decision-Making in Dynamically Changing Conditions

Autor: Mahsa Dadar, Lesley K. Fellows, Alain Dagher, Yashar Zeighami, Yvonne H. C. Yau, Madeline Taylor, Paul Cisek

Publikováno v: Cereb Cortex

Current models of decision-making assume that the brain gradually accumulates evidence and drifts toward a threshold that, once crossed, results in a choice selection. These models have been especially successful in primate research; however, transpo

Orbitofrontal-Striatal Structural Alterations Linked to Negative Symptoms at Different Stages of the Schizophrenia Spectrum

Publikováno v: Schizophrenia Bulletin, Vol. 47, No 3 (2021) pp. 849-863
Schizophr Bull

Negative symptoms such as anhedonia and apathy are among the most debilitating manifestations of schizophrenia (SZ). Imaging studies have linked these symptoms to morphometric abnormalities in 2 brain regions implicated in reward and motivation: the

Biological Underpinning of Behavioral Addictions and Management Implications

Autor: Yvonne H. C. Yau, Robert F. Leeman, Marc N. Potenza

Publikováno v: Textbook of Addiction Treatment ISBN: 9783030363901

Neurobiological and clinical data indicate that maladaptive engagement in certain behaviors warrants consideration as “behavioral” or non-substance addictions. This chapter reviews existing neurobiological and genetic/family history evidence for

Evidence and urgency related EEG signals during dynamic decision-making in humans

Autor: Lesley K. Fellows, Alain Dagher, Thomas Hinault, Madeline Taylor, Yvonne H. C. Yau, Paul Cisek

Publikováno v: J Neurosci

A successful class of models link decision-making to brain signals by assuming that evidence accumulates to a decision threshold. These evidence accumulation models have identified neuronal activity that appears to reflect sensory evidence and decisi

Digital Technology Use and Overuse

Autor: Yvonne H. C. Yau, Marc N. Potenza

Digital technologies are rapidly gaining in popularity and impact. Discussions continue on whether excessive engagement in digital technologies, such as problematic Internet use and video game playing, merit consideration as behavioral addictions. Th

Relationship between impulsivity, uncontrolled eating and body mass index: a hierarchical model

Autor: Stephanie G. Scala, Uku Vainik, Yvonne H. C. Yau, Natalie Sun, D. Louis Collins, Filip Morys, Mahsa Dadar, Yashar Zeighami, Selin Neseliler, Alain Dagher, Isabel García-García

Publikováno v: International journal of obesity (2005). 46(1)

Impulsivity increases the risk for obesity and weight gain. However, the precise role of impulsivity in the aetiology of overeating behavior and obesity is currently unknown. Here we examined the relationships between personality-related measures of

White matter hyperintensities are linked to future cognitive decline in de novo Parkinson's disease patients

White Matter Hyperintensities (WMHs) are associated with cognitive decline in aging and Alzheimer's disease. However, the pathogenesis of cognitive decline in Parkinson's disease (PD) is not as clearly related to vascular causes, and therefore the ro

Sex effects on brain structure in de novo Parkinson's disease: a multimodal neuroimaging study

Autor: Yashar Zeighami, Nooshin Abbasi, Shady Rahayel, Alain Dagher, Yvonne H. C. Yau, Christina Tremblay, Mahsa Dadar

Publikováno v: Brain : a journal of neurology. 143(10)

Parkinson’s disease varies in severity and age of onset. One source of this variability is sex. Males are twice as likely as females to develop Parkinson’s disease, and tend to have more severe symptoms and greater speed of progression. However,

BackgroundMRI studies show that obese adults have reduced grey (GM) and white matter (WM) tissue density as well as altered WM integrity. It remains to be examined if bariatric surgery induces structural brain changes. The aim of this study is to cha
