- Working memory effects on semantic processing: priming differences in pars orbitalisFred W Sabb
Semel Institute for Neuroscience and Human Behavior, Department of Psychiatry, University of California, Los Angeles 760 Westwood Plaza, Los Angeles, CA 90095, USA
Neuroimage 37:311-22. 2007..fMRI signal changes in dorsolateral prefrontal cortex were negatively correlated with signal changes in pars orbitalis. The findings suggest that controlled semantic processing and working memory share neural system resources...
- Selective corticostriatal dysfunction in schizophrenia: examination of motor and cognitive skill learningKarin Foerde
Department of Psychology, University of California Los Angeles, Los Angeles, CA, USA
Neuropsychology 22:100-9. 2008..In contrast, patients were not impaired at learning on the SRT relative to controls, suggesting that patients with schizophrenia may have dysfunction in a specific corticostriatal subcircuit...
- A unique adolescent response to reward prediction errorsJessica R Cohen
Department of Psychology, University of California Los Angeles, Los Angeles, California, USA
Nat Neurosci 13:669-71. 2010..This suggests that heightened dopaminergic prediction error responsivity contributes to adolescent reward seeking...
- Women are more sensitive than men to prior trial events on the Stop-signal taskKatharine N Thakkar
Semel Institute, University of California, Los Angeles UCLA, USA Department of Psychology, Vanderbilt University, Nashville, Tennessee, USA
Br J Psychol 105:254-72. 2014..These small but statistically significant effects (Cohen's d = 0.25-0.3) suggest more flexible adjustments in speed-accuracy trade-offs in women and greater cognitive flexibility associated with the responsive control of action. ..
- Language network dysfunction as a predictor of outcome in youth at clinical high risk for psychosisFred W Sabb
Department of Psychiatry and Biobehavioral Sciences, University of California, Los Angeles, Box 956968, Rm 2265, 300 Medical Plaza, Los Angeles, CA 90095 6968, USA
Schizophr Res 116:173-83. 2010..Yet, no study to date has investigated underlying neural networks associated with discourse processing in adolescents at clinical high risk (CHR) for developing psychosis(1)...
- The genetics of cognitive impairment in schizophrenia: a phenomic perspectiveRobert M Bilder
Department of Psychiatry and Biobehavioral Sciences, David Geffen School of Medicine, University of California, Los Angeles, CA 90095, USA
Trends Cogn Sci 15:428-35. 2011....
- Neural activation during response inhibition in adult attention-deficit/hyperactivity disorder: preliminary findings on the effects of medication and symptom severityEliza Congdon
Department of Psychiatry and Biobehavioral Sciences, David Geffen School of Medicine, Semel Institute for Neuroscience and Human Behavior, University of California Los Angeles, Los Angeles, CA, USA Electronic address
Psychiatry Res 222:17-28. 2014..These findings help to explain some of the disparities in the literature, and advance our understanding of why deficits in response inhibition are more variable in adult, as compared with child and adolescent, ADHD patients. ..
- Specificity of brain activation patterns in people at genetic risk for Alzheimer diseaseAlison C Burggren
Department of Psychiatry and Biobehavioral Sciences, Brain Mapping Division, UCLA School of Medicine, Los Angeles, CA 90095 7085, USA
Am J Geriatr Psychiatry 10:44-51. 2002....
- The neural correlates of motor skill automaticityRussell A Poldrack
Department of Psychology, University of California, Los Angeles, Los Angeles, California 90095 1563, USA

- Cognitive ontologies for neuropsychiatric phenomics researchRobert M Bilder
Jane and Terry Semel Institute for Neuroscience and Human Behavior at UCLA, Los Angeles, CA 90095, USA
Cogn Neuropsychiatry 14:419-50. 2009..It is hoped that these tools will help formalise inference about cognitive concepts in behavioural and neuroimaging studies, and facilitate discovery of the genetic bases of both healthy cognition and cognitive disorders...
- The Barratt Impulsiveness Scale-11: reassessment of its structure in a community sampleSteven P Reise
Department of Psychology, Universityof California, Los Angeles, Los Angeles, CA90095, USA
Psychol Assess 25:631-42. 2013..Also, the theory that the BIS-11 measures 3 subdomains of impulsivity (attention, motor, and nonplanning) was not empirically supported. A 2-factor model is offered as an alternative multidimensional structural representation...
- Executive function in pediatric bipolar disorder and attention-deficit hyperactivity disorder: in search of distinct phenotypic profilesPatricia D Walshaw
Department of Psychiatry and Biobehavioral Science, University of California Los Angeles, Los Angeles, CA, USA
Neuropsychol Rev 20:103-20. 2010..These differences may begin to establish a pediatric BD profile that provides a more objective means of differential diagnosis between BD and ADHD when they are not reliably distinguished by clinical diagnostic methods...
- Recruitment of anterior dorsolateral prefrontal cortex in human reasoning: a parametric study of relational complexityJames K Kroger
Department of Psychology, University of Michigan, Ann Arbor, MI 48109 1109, USA
Cereb Cortex 12:477-85. 2002..Our data provide evidence that brain regions specific to integrating complex relations among stimuli are distinct from those involved in coping with general task difficulty and with working-memory demands...
