Cognitive, Affective and Behavioral Neuroscience back issues from June 2007:
On how high performers keep cool brains in situations of cognitive overload
Jun 01, 2007; ... What happens in the brain when we reach or exceed our capacity limits? Are there individual differences for performance at capacity limits? We used functional magnetic resonance imaging (fMRI) to investigate the impact of increases in processing demand on selected cortical areas when ...
Models in search of a brain
Jun 01, 2007; ... Mental localization efforts tend to stress the where more than the what. We argue that the proper targets for localization are well-specified cognitive models. We make this case by relating an existing cognitive model of category learning to a learning circuit involving the hippocampus, ...
Mindfulness training modifies subsystems of attention
Jun 01, 2007; ... Mindfulness is defined as paying attention in the present moment. We investigate the hypothesis that mindfulness training may alter or enhance specific aspects of attention. We examined three functionally and neuroanatomically distinct but overlapping attentional subsystems: alerting, orienting, ...
Differential effects of scopolamine and lorazepam on working memory maintenance versus manipulation processes
Jun 01, 2007; ... Between-study comparisons of benzodiazepine and anticholinergic drugs on working memory suggest that anticholinergics may produce greater impairment in maintenance processes, whereas benzodiazepines may produce greater impairment in manipulation processes. This study directly compared acute ...
Neural bases of focusing attention in working memory: An fMRI study based on group differences
Jun 01, 2007; ... Using fMRI, we investigated neural substrates for focusing attention in working memory. To explore this focusing effect, two kinds of reading span test (RST), focused and nonfocused, were performed. In the focused RST (F-RST), the target word to be maintained was the focus word in the sentence ....
Neural correlates of emotional intelligence in adolescent children
Jun 01, 2007; ... The somatic marker hypothesis posits a key role for the ventromedial prefrontal cortex, amygdala, and insula in the ability to utilize emotions to guide decision making and behavior. However, the relationship between activity in these brain regions and emotional intelligence (EQ) during ...
