“…Although this type of protocol has been extensively used in prior studies (e.g. Hu et al, 2006;Payne et al, 2008), we need to rule out circadian influences in our measurements. Firstly, there was no significant group difference in objective (PVT) and subjective (KSS) vigilance levels across experimental sessions.…”

“…Compliance to the schedule was assessed using a sleep diary and wrist actigraphy (Actiwatch, Cambridge Neuroscience, Cambridge, UK). Because we aimed at minimizing any experimental stressors (see Results section), the participants from the Sleep group slept in familiar conditions at their home with actimetry (but no EEG) (Hu et al, 2006;Payne et al, 2008).…”

Sleep sharpens sensory stimulus coding in human visual cortex after fear conditioning

Efficient perceptual identification of emotionally-relevant stimuli requires optimized neural coding. Because sleep contributes to neural plasticity mechanisms, we asked whether the perceptual representation of emotionally-relevant stimuli within sensory cortices is modified after a period of sleep. We show combined effects of sleep and aversive conditioning on subsequent discrimination of face identity information, with parallel plasticity in the amygdala and visual cortex. After one night of sleep (but neither immediately nor after an equal waking interval), a fear-conditioned face was better detected when morphed with another identity. This behavioral change was accompanied by increased selectivity of the amygdala and face-responsive fusiform regions. Overnight neural changes can thus sharpen the representation of threat-related stimuli in cortical sensory areas, in order to improve detection in impoverished or ambiguous situations. These findings reveal an important role of sleep in shaping cortical selectivity to emotionally-relevant cues and thus promoting adaptive responses to new dangers.

“…Positive effects of sleep on emotional memories have been reported at the behavioral level. Retrieval of emotional (relative to neutral) material several hours after encoding is enhanced if the interval contains an episode of sleep (Hu et al, 2006;Payne et al, 2008;Nishida et al, 2009), especially rapid eye movement (REM) sleep (Wagner et al, 2001), rather than a period of wake. This sleep-dependent advantage persists 4 years later (Wagner et al, 2006).…”

Sleep promotes memory consolidation, a process by which fresh and labile memories are reorganized into stable memories. Emotional memories are usually better remembered than neutral ones, even at long retention delays. In this study, we assessed the influence of sleep during the night after encoding onto the neural correlates of recollection of emotional memories 6 months later. After incidental encoding of emotional and neutral pictures, one-half of the subjects were allowed to sleep, whereas the others were totally sleep deprived, on the first postencoding night. During subsequent retest, functional magnetic resonance imaging sessions taking place 3 d and 6 months later, subjects made recognition memory judgments about the previously studied and new pictures. Between these retest sessions, all participants slept as usual at home. At 6 month retest, recollection was associated with significantly larger responses in subjects allowed to sleep than in sleep-deprived subjects, in the ventral medial prefrontal cortex (vMPFC) and the precuneus, two areas involved in memory retrieval, as well as in the extended amygdala and the occipital cortex, two regions the response of which was modulated by emotion at encoding. Moreover, the functional connectivity was enhanced between the vMPFC and the precuneus, as well as between the extended amygdala, the vMPFC, and the occipital cortex in the sleep group relative to the sleep-deprived group. These results suggest that sleep during the first postencoding night profoundly influences the long-term systems-level consolidation of emotional memory and modifies the functional segregation and integration associated with recollection in the long term.

“…Emotional stimuli are known to influence memory processes at various levels, beginning at encoding and extending to consolidation and retrieval stages (Payne, Stickgold, Swanberg, & Kensinger, 2008;Phelps, 2004). Several studies have demonstrated boosts in recollection (Ochsner, 2000) and in memory for details of negative visual scenes and objects (Canli, Zhao, Brewer, Gabrieli, & Cahill, 2000;Kensinger, Garoff-Eaton, & Schacter, 2007a, 2007b.…”

Emotional context at learning systematically biases memory for facial information

Emotion influences memory in many ways. For example, when a mood-dependent processing shift is operative, happy moods promote global processing and sad moods direct attention to local features of complex visual stimuli. We hypothesized that an emotional context associated with to-be-learned facial stimuli could preferentially promote global or local processing. At learning, faces with neutral expressions were paired with a narrative providing either a happy or a sad context. At test, faces were presented in an upright or inverted orientation, emphasizing configural or analytical processing, respectively. A recognition advantage was found for upright faces learned in happy contexts relative to those in sad contexts, whereas recognition was better for inverted faces learned in sad contexts than for those in happy contexts. We thus infer that a positive emotional context prompted more effective storage of holistic, configural, or global facial information, whereas a negative emotional context prompted relatively more effective storage of local or feature-based facial information.
