- The restorative effect of naps on perceptual deteriorationSara C Mednick
Department of Psychology, Harvard University, 33 Kirkland Street, Cambridge, Massachusetts 02138, USA
Nat Neurosci 5:677-81. 2002..This performance deterioration was prevented either by shifting the target stimuli to an untrained region of visual space or by having the subjects take a mid-day nap between the second and third sessions...
- An opportunistic theory of cellular and systems consolidationSara C Mednick
University of California, San Diego, Department of Psychiatry 9116A, 3350 La Jolla Village Drive, San Diego, CA 92116, USA
Trends Neurosci 34:504-14. 2011..Instead, the brain opportunistically consolidates previously encoded memories whenever the hippocampus is not otherwise occupied by the task of encoding new memories...
- The spread of sleep loss influences drug use in adolescent social networksSara C Mednick
Department of Psychiatry, University of California San Diego, La Jolla, California, United States of America
PLoS ONE 5:e9775. 2010..The results indicate that interventions should focus on healthy sleep to prevent drug use and targeting specific individuals may improve outcomes across the entire social network...
- Sleep and rest facilitate implicit memory in a visual search taskS C Mednick
Department of Psychiatry and Veterans Affairs, San Diego Healthcare System, University of California, San Diego, Research Service, La Jolla, CA 92161, United States
Vision Res 49:2557-65. 2009..They prompt a reevaluation of the hippocampal replay hypothesis as a general model of sleep-dependent learning...
- Perceptual deterioration is reflected in the neural response: fMRI study of nappers and non-nappersSara C Mednick
University of California San Diego, San Diego, CA, USA
Perception 37:1086-97. 2008..Without a nap, perceptual deterioration was related to decreases in the stimulus-driven, bottom-up representation, rather than decreases in attentional modulation to the stimulus...
- Comparing the benefits of caffeine, naps and placebo on verbal, motor and perceptual memorySara C Mednick
University of California, San Diego, Department of Psychiatry and Veterans Affairs San Diego Healthcare System, Research Service, United States
Behav Brain Res 193:79-86. 2008..We hypothesize that impairment from caffeine may be restricted to tasks that contain explicit information; whereas strictly implicit learning is less compromised...
- Sleep-dependent learning and practice-dependent deterioration in an orientation discrimination taskSara C Mednick
Department of Psychiatry, University of California, San Diego, Research Service, VA San Diego Healthcare System, USA
Behav Neurosci 122:267-72. 2008..e., produces learning), but does not prevent over-practice deterioration effects. Likewise, over-practice deterioration does not influence the magnitude of overnight learning on this task...
- The neural basis of the psychomotor vigilance taskSean P A Drummond
University of California San Diego, Department of Psychiatry, 92161, USA
Sleep 28:1059-68. 2005..To identify brain regions underlying the fastest and slowest reaction times on the Psychomotor Vigilance task (PVT) under well-rested conditions, as well as brain regions related to particularly poor performance after sleep deprivation...
- The time course and specificity of perceptual deteriorationSara C Mednick
The Salk Institute for Biological Studies, SNL B, 10010 North Torrey Pines Road, La Jolla, CA 92037 1099, USA
Proc Natl Acad Sci U S A 102:3881-5. 2005..Further, the differences in specificity profiles between learning and deterioration suggest separate underlying mechanisms that occur within the same cortical area...
- The role of sleep and practice in implicit and explicit motor learningCory A Rieth
University of California, San Diego, Department of Psychology, United States
Behav Brain Res 214:470-4. 2010..Controlling for non-sleep factors (e.g. massed practice, circadian confounds) eliminated both explicit and implicit learning effects that have been attributed to sleep...
