Long-term memory has back-up plan,researchers find
Long-term memory back-up plan researchers
2016/5/19
A team of scientists has identified the existence of a back-up plan for memory storage, which comes into play when the molecular mechanism of primary long-term memory storage fails.Previous work had s...
Multiple, short learning sessions strengthen memory formation in fragile X syndrome
Multiple short learning sessions strengthen memory formation fragile X syndrome
2014/12/30
Christine Gall, Gary Lynch and colleagues found that fragile X model mice trained in three short, repetitious episodes spaced one hour apart performed as well on memory tests as normal mice. These sam...
Cognitive Demand and Reminders Effect on Time-Based Prospective Memory in Amnesic Mild Cognitive Impairment (AMCI) and in Healthy Elderly
AMCI Prospective Memory Time Monitoring Memory Reminder
2013/1/31
Individuals with-Mild Cognitive Impairment (MCI) often complain of difficulty remembering to carry out intended actions. We investigated the relative efficacy of a different reminder in performing a t...
Sleep Deprivation Affects Working Memory in Low but Not in High Complexity for the N-Back Test
Sleep Deprivation Working Memory Cortisol Levels N-Back Task Stress
2013/1/30
Sleep clearly influences learning and memory since sleep deprivation and stress impairs both cognitive processes. Working memory is an essential cognitive process and refers to a short-term holding of...
A Twenty-Year Follow-up Case Study of an Office Worker Who Returned to Work despite Serious Memory Disorder Caused by Herpes Encephalitis
Declarative Memory Semantic Memory Procedural Memory
2013/1/29
This study followed a 52-year-old male patient, who had suffered from severe impairment in recent memory due to se- quelae of herpes encephalitis, for 20 years. He returned to his highly intellectual ...
Persistent delayed auditory memory and executive function deficits 5 years after West Nile Virus Encephalitis: A neuropsychological and neuroimaging single case study
West Nile Virus West Nile Virus Neuroinvasive Disease
2013/2/20
There are presently no in-depth published neuropsychological studies of West Nile Virus (WNV) encephalitis patients that have been well-correlated with high resolution structural MRI. In this study a ...
Structural neuroimaging and neuropsychological correlates of a single case of focal central pontine myelinolysis: Intact memory function with decreased intellectual and motor functions
Central Pontine Myelinolysis Neuropsychology
2013/2/20
We report on the case of middle-aged right-handed woman with central pontine myelinolysis (CPM) revealed by high resolution structural T2-weighted FLAIR MRI imaging. There was a general flattening of ...

Influences of reduced masticatory sensory input from soft-diet feeding upon spatial memory/learning ability in mice
reduced masticatory sensory soft-diet feeding spatial memory/learning ability mice
2009/3/2
It has been reported that reduction of masticatory afferent stimulation might influence learning and memory function. In order to clarify the influences of reduced masticatory sensory input on spatial...
Fabrication and in vitro deployment of a laser-activated shape memory polymer vascular stent
a laser-activated shape memory polymer vascular stent Fabrication
2010/2/25
Vascular stents are small tubular scaffolds used in the treatment of arterial stenosis (narrowing of the vessel). Most vascular stents are metallic and are deployed either by balloon expansion or by s...
