Heterotrimeric G protein alpha subunits, RGS proteins, and GoLoco motif proteins have been recently implicated in the control of mitotic spindle dynamics in C. elegans and D. melanogaster. Here we show that "regulator of G protein signaling-14" (RGS14) is expressed by the mouse embryonic genome immediately prior to the first mitosis, where it colocalizes with the anastral mitotic apparatus of the mouse zygote. Loss of Rgs14 expression in the mouse zygote results in cytofragmentation and failure to progress to the 2-cell stage. RGS14 is found in all tissues and segregates to the nucleus in interphase and to the mitotic spindle …

Gaps In Accessing Treatment For Anxiety And Depression: Challenges For The Delivery Of Care., Kerry A Collins, Henny A Westra, David J A Dozois, David D Burns

Epidemiological studies have identified high prevalence rates of anxiety and depression in North America [e.g., J. of Nerv. Ment. Dis. 182 (1994) 290]. However, only a small percentage of these individuals access effective treatment. The undertreatment of anxiety and depression is a major public health issue and is associated with significant personal, social, and economic burden. This article describes the existing discrepancy between prevalence of anxiety and depression and access to effective treatment for adults and children, the contributors to this discrepancy, and suggests various means through which access to effective treatment may be enhanced. We begin with a brief …
Somatotopic Representation Of Action Words In Human Motor And Premotor Cortex, Olaf Hauk, Ingrid Johnsrude, Friedemann Pulvermüller
Somatotopic Representation Of Action Words In Human Motor And Premotor Cortex, Olaf Hauk, Ingrid Johnsrude, Friedemann Pulvermüller
Brain and Mind Institute Researchers' Publications
Since the early days of research into language and the brain, word meaning was assumed to be processed in specific brain regions, which most modern neuroscientists localize to the left temporal lobe. Here we use event-related fMRI to show that action words referring to face, arm, or leg actions (e.g., to lick, pick, or kick), when presented in a passive reading task, differentially activated areas along the motor strip that either were directly adjacent to or overlapped with areas activated by actual movement of the tongue, fingers, or feet. These results demonstrate that the referential meaning of action words has …
Attentional Biases In Eating Disorders: A Meta-Analytic Review Of Stroop Performance., Keith S Dobson, David J A Dozois
Attentional Biases In Eating Disorders: A Meta-Analytic Review Of Stroop Performance., Keith S Dobson, David J A Dozois
Psychology Publications
The Stroop task has been adapted from cognitive psychology to be able to examine attentional biases in various forms of psychopathology, including the eating disorders. This paper reviews the research on the Stroop task in the eating disorders research area in both descriptive and meta-analytic fashions. Twenty-eight empirical studies are identified, which predominantly examine food and body/weight stimuli in bulimic, anorexic, or dieting/food-restricted samples. It is concluded that there is evidence of an attentional bias in bulimia for a range of stimuli but that the effect seems to be limited to body/weight stimuli in anorexia. The evidence to date is …
