Acute stress has been shown to modulate memory for recently learned information, an effect attributed to the influence of stress hormones on medial temporal lobe (MTL) consolidation processes. However, little is known about which memories will be affected when stress follows encoding. One possibility is that stress interacts with encoding processes to selectively protect memories that had elici...

STUDY OBJECTIVES Examine the role of sleep in the consolidation of declarative memory in children with autism spectrum disorder (ASD). DESIGN Case-control study. SETTING Home-based study with sleep and wake conditions. PARTICIPANTS Twenty-two participants with ASD and 20 control participants between 9 and 16 y of age. MEASUREMENTS AND RESULTS Participants were trained to criterion on a ...

BACKGROUND Abnormalities in fear extinction and recall are core components of posttraumatic stress disorder (PTSD). Data from animal and human studies point to a role of the ventromedial prefrontal cortex (vmPFC) in extinction learning and subsequent retention of extinction memories. Given the increasing interest in developing noninvasive brain stimulation protocols for psychopathology treatmen...

This study examines the effect of consolidation Deposit Money Banks (DMBs) on credit access risk in rural areas Nigeria after a decade exercise. Secondary data total value credits to was obtained from CBN bulletin for period 1994 2014. includes 10 years pre and post-consolidation. Mann Whitney U test used analysing significant difference before Nigeria. The result revealed that there increase D...

expansive soils are of the kind the volume of which will be changed to extremes by being exposed to varying conditions of moisture. this volume change is a serious menace to structures built on these types of soils. throughout the present research the potential of volume change in these soils was investigated when exposed to the phenomenon of wetting and drying. for the purpose, samples of a st...

BACKGROUND/AIMS Paraquat-induced lung injury has been considered a progressive and irreversible disease. The purpose of this study was to report the long-term evolution of lung lesions in eight survivors with significant paraquat-induced lung injuries who could be followed-up for longer than 6 months. METHODS We retrospectively examined high-resolution computed tomography and pulmonary functi...

The central nucleus of the amygdala (CeA) has been traditionally viewed in fear conditioning to serve as an output neural center that transfers conditioned information formed in the basolateral amygdala to brain structures that generate emotional responses. Recent studies suggest that the CeA may also be involved in fear memory consolidation. In addition, corticotropin-releasing factor systems ...

Sleep supports memory consolidation. However, the conceptually important influence of the amount of items encoded in a memory test on this effect has not been investigated. In two experiments, participants (n = 101) learned lists of word-pairs varying in length (40, 160, 320 word-pairs) in the evening before a night of sleep (sleep group) or of sleep deprivation (wake group). After 36 h (includ...

Considerable evidence support the role of sleep in learning and memory processes. In rodents, the relationships between sleep and memory consolidation have been extensively investigated by taking into account mainly spatial learning. On the contrary, in humans the relationship between sleep and spatial memory consolidation has so far been scarcely taken into account. Here, we investigated the i...
