OBJECTIVES The primary objective of this study was to investigate the effects of five consecutive, daily 20-minute sessions of M1 a-tDCS on motor learning in healthy, cognitively intact, aging adults. DESIGN A total of 23 participants (51 to 69 years old) performed five consecutive, daily 20-minute sessions of a serial reaction time task (SRT task)(More)
Memory consolidation is associated with sleep physiology but the contribution of specific sleep stages remains controversial. To clarify the contribution of REM sleep, participants were administered two REM sleep-sensitive tasks to determine if associated changes occurred only in REM sleep. Twenty-two participants (7 men) were administered the Corsi Block(More)
Although sleep facilitates learning and memory, the roles of dreaming and habitual levels of recalling dreams remain unknown. This study examined if performance and overnight improvement on a rapid eye movement sleep-sensitive visuomotor task is associated differentially with habitually high or low dream recall frequency. As a relation between dream(More)
The sleep of individuals suffering from frequent non-traumatic nightmares (NM) could prove useful in uncovering neural mechanisms involved in NM production. Past research has shown enhanced relative 10-14.5Hz activity ('high alpha') during REM sleep in frequent NM recallers, while other findings are consistent with a role for theta activity in REM-dependent(More)
