A number of neuropsychological studies in recent years have shown that demented patients do not necessarily present a global deterioration and that the disease can impair some cognitive processes or systems, while sparing others. Moreover, qualitatively different patterns of cognitive impairment have been identified in association with different types of neurodegenerative dementias, such as Alzheimer's disease, Huntington's disease, Parkinson's disease or frontotemporal dementia.

Les concepts d'attention et de mémoire de travail ont très souvent été considérés de façon distincte, que ce soit dans le domaine de la recherche ou dans celui de la pratique clinique en neuropsychologie. Or, une analyse détaillée des modèles théoriques de l'attention et de la mémoire de travail indique au contraire qu'il existe un large recouvrement entre ces deux domaines. L'objectif de ce chapitre est de mettre en exergue ces relations et recouvrements. Plus spécifiquement, nous montrerons en quoi la mémoire de travail a une fonction essentielle de contrôle attentionnel de l'action, nous décrirons les études d'imagerie fonctionnelle ayant exploré les bases cérébrales de cette fonction de contrôle attentionnel et nous présenterons enfin quelques travaux ayant mis en évidence une relation spécifique entre mémoire de travail, attention sélective et vigilance.

Interactions between the neural correlates of short-term memory (STM) and attention have been actively studied in the visual STM domain but much less in the verbal STM domain. Here we show that the same attention mechanisms that have been shown to shape the neural networks of visual STM also shape those of verbal STM. Based on previous research in visual STM, we contrasted the involvement of a dorsal attention network centered on the intraparietal sulcus supporting task-related attention and a ventral attention network centered on the temporoparietal junction supporting stimulus-related attention. We observed that, with increasing STM load, the dorsal attention network was activated while the ventral attention network was deactivated, especially during early maintenance. Importantly, activation in the ventral attention network increased in response to task-irrelevant stimuli briefly presented during the maintenance phase of the STM trials but only during low-load STM conditions, which were associated with the lowest levels of activity in the dorsal attention network during encoding and early maintenance. By demonstrating a trade-off between task-related and stimulus-related attention networks during verbal STM, this study highlights the dynamics of attentional processes involved in verbal STM.

Auto-referential materials (i.e., the own name) have been described as particularly prone to capture attention. Some recent studies have questioned this view and shown that these own name effects are temporary and appear only in specific conditions: when enough resources are available (Harris, C. R., & Pashler, H. (2004). Attention and the processing of emotional words and names: Not so special after all. Psychological Science, 15, 171-178) or when the own name is presented within the focus of attention if it is a task-irrelevant stimulus (Gronau, N., Cohen, A., & Ben-Shakhar, G. (2003). Dissociations of personally significant and task-relevant distractors inside and outside the focus of attention: A combined behavioral and psychophysiological study. Journal of Experimental Psychology: General, 132, 512-529). In the present study, a stimulus that is unique to each individual was used: the self-face. In Experiment 1, the self-face produced a temporary distraction when presented at fixation during a digit-parity task. However, this distraction was not different from that triggered by another highly familiar face. In Experiment 2, the self-face failed to produce interference when presented outside the focus of attention. These results confirm recent findings showing that auto-referential materials do not automatically summon attention and have a distractive power only in specific conditions. [less ▲]

Auto-referential materials (own name) have been described as particularly prone to capture attention. Some recent studies by Harris and Pashler (2004 Psychological Science 15 171 - 178) and Gronau et al (2003 Journal of Experimental Psychology: General 132 512 - 529) have questioned this view and showed that these own-name effects are temporary and appear only in specific conditions: when enough resources are available or when the own name is a task-irrelevant stimulus presented in the focus of attention.

However, this distraction was not different from that triggered by another highly familiar face. In experiment 2, familiar faces failed to produce interference when presented outside the focus of attention. Experiment 3, using a less demanding task, indicated that when few resources are required, the self-face may interfere even when presented peripherally. These results confirm recent findings showing that auto-referential materials are special only in specific conditions. [less ▲]

The interpretation of the data regarding cognitive outcome in children who have suffered from mild traumatic brain injury (MTBI) remains currently controversial. The aim of the present study is to explore attentional and executive functioning in 6–12-year-old children who experienced a MTBI. A total of 15 children with MTBI and 15 matched noninjured children participated in the study. Attentional tasks using the Test for Attentional Performance battery were administered one year after the injury. In comparison to the noninjury children, MTBI children performed less accurately on selective attentional and updating tasks. These preliminary findings support the view that MTBI can have an impact on specific attentional functioning in children one year postinjury. [less ▲]

BACKGROUND: Attentional dysfunction in children after corrective cardiac surgery in infancy has rarely been evaluated and is the topic of the present work. METHODS: Forty unselected children, 20 with tetralogy of Fallot and hypoxemia and 20 with ventricular septal defect and cardiac insufficiency, operated on at a mean age 0.7 (SD 0.3) years with deep hypothermic circulatory arrest and low flow cardiopulmonary bypass, were evaluated at mean age 7.4 (SD 1.6) years by the computerized form of the Attention Network Test providing performance measures of three networks of attention: alerting, orienting, and executive control. Parental ratings of attentional dysfunction were derived from the Child Behavior Checklist. Results were compared with healthy controls, between patient groups, and correlated with perioperative risk factors and current neurodevelopmental status. RESULTS: Executive control was reduced in the tetralogy of Fallot group, alerting and orienting were found normal and not different between patient groups. Durations of aortic cross clamping inversely correlated with orienting; durations of cardiopulmonary bypass correlated with mean reaction time and inversely correlated with executive control. Motor function and acquired abilities correlated with executive control and orienting. Parent-reported problems on the Child Behavior Checklist inversely correlated with executive control and mean accuracy. CONCLUSIONS: Children with preoperative hypoxemia in infancy due to cyanotic cardiac defects are at increased risk for attentional dysfunction in the field of executive control, compared with normal children and with those who have acyanotic heart defects. Besides unfavorable perioperative influences, preoperative hypoxemia is considered responsible for additional damage to the highly oxygen sensitive regions of the prefrontal cortex and striate body assumed to be associated with the executive control network of attention.

A wild-type strain of channel catfish virus was compared at the genomic level with the attenuated strain V60. In addition to several minor differences, restriction mapping revealed one major deletion (approximately 1200 bp) in ORF50 of the V60 strain. Cloning and sequencing of part of this ORF confirmed the presence of a 1164-bp deletion. It should result in a protein of 282 amino acids instead of 670. The predicted truncated protein lacks most of a threonine-rich, highly repetitive region in its central part. Since the protein encoded by ORF50 possesses a hydrophobic N-terminal leader sequence and no membrane anchor sequence, we suggest that it could be a secreted glycoprotein. This protein might be N-glycosylated (35 potential sites) and, given the repetitive arrangement of its residues (mainly threonines), also heavily O-glycosylated like the mucin-type glycoproteins. The deletion observed in ORF50 of the V60 strain implies the loss of 24 potential N-glycosylation sites and should considerably reduce the extent of O-glycosylation. [less ▲]

Chronic arterial hypotension has been poorly studied. Its mechanisms are not well understood; its treatment (if needed) is disappointing, without any demonstrated improvement of symptoms or prognosis. Thus, a complete medical examination is needed to exclude any organic cause. If none is found, it is important to reassure the patient and to convince him not to use expensive drugs potentially generative of side effects. [less ▲]
