Sleep-dependent learning and memory consolidation. (2004, neutral): “(Fischer et al., 2002; Gais et al., 2000; Karni et al., 1994; Korman et al., 2003;”
Daytime Naps, Motor Memory Consolidation and Regionally Specific Sleep Spindles (2007, result): “Offline, practice-independent learning Consistent with previous findings [4,9,17–19], there was no evidence of delayed offline memory enhancement across the day in those subjects that remained awake.”
Sleep-dependent learning and motor-skill complexity. (2004, background): “For example, although there appears to be no transfer of this sleep-dependent learning to new motor sequences or to performance by the other hand (Fischer et al. 2002; Korman et al. 2003), it is not clear whether sleepdependent learning occurs when the trained sequence requires bimanual performance ”
Sleeping on the motor engram: The multifaceted nature of sleep‐related motor memory consolidation (2017, positive): “…the consolidation of previously learned – as compared to new – sequential pattern in a variety of tasks including implicit sequential tracking (Maquet et al., 2003), implicit serial oculomotor sequence learning (Albouy et al., 2008, 2006) and explicit finger sequence learning (Korman et al., 2003).”
Sleep-Dependent Reactivation of Ensembles in Motor Cortex Promotes Skill Consolidation (2015, neutral): “, the associative, prefrontal-connected portions) [3,12,60,62–68].”
The restless engram: consolidations never end. (2012, background): “, by loosening the bonds of associative memory representations and thereby disintegrating elements of these memories (Stickgold and Walker, 2013; Korman et al., 2005; Cai et al., 2009; Sterpenich et al., 2014; Landmann et al., 2015).”
Neuroplasticity subserving motor skill learning (2011, positive): “Offline processes, including skill stabilization and improvement (Fischer et al., 2005; Korman et al., 2003; Walker et al., 2002), reflect motor memory consolidation (Doyon and Benali, 2005; Muellbacher et al.”
Current concepts in procedural consolidation (2004, background): “Similar overnight improvements are seen in the performance of short sequences of finger movement”
Sleep spindles predict neural and behavioral changes in motor sequence consolidation (2013, background): “In recent years, a large body of evidence has demonstrated that the consolidation of motor sequence learning (MSL), as measured through offline gains in performance on a task, is sleep-dependent [Doyon et al., 2009b; Fischer et al., 2002; Korman et al., 2003; Walker et al., 2002].”
Daytime Sleep Enhances Consolidation of the Spatial but Not Motoric Representation of Motor Sequence Memory (2013, background): “It should be noted, however, that some other studies have reported a preferential transfer effect either on the motor [14,16,22,48,49] or spatial representation of the sequence [6,7,10,47].”
Sleep-dependent motor memory plasticity in the human brain. (2005, neutral): “Adding to these findings, it also appears that there is no transfer of sleep-dependent procedural learning to either new motor sequences, or to performance of the same sequence using the opposite hand (Fischer et al., 2002; Korman et al., 2003), suggesting that the influence of sleep is highly speci”
Human functional neuroimaging of brain changes associated with practice. (2005, background): “A number of researchers suggest that there is a particular signature of neural change associated with practice in primary motor or sensory cortex (e.g. Hikosaka et al., 1998; Karni et al., 1998; Hikosaka et al., 2002; Ungerleider et al., 2002; Korman et al., 2003; Kleim et al., 2004).”
About sleep's role in memory. (2013, neutral): “, a gain in skill at a later retesting) have pointed towards an active reprocessing of skill representations occurring during sleep that sharpens the respective representations (47, 57, 147, 274, 275, 291, 322, 383, 384, 433, 582, 622, 631, 664, 665, 679, 762, 770, 808, 810, 863, 930, 1003, 1153, 11”
