Dissociating memory networks in early Alzheimer's disease and frontotemporal lobar degeneration - a combined study of hypometabolism and atrophy

, 2013
Introduction: We aimed at dissociating the neural correlates of memory disorders in Alzheimer’s disease (AD) and frontotemporal lobar degeneration (FTLD).

Baseline Regional Cholinergic Denervation Predicts Cognitive Trajectories in Moderate Parkinson Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive decline is a disabling and variable feature of Parkinson disease (PD). While cholinergic system degeneration is linked to cognitive impairments in PD, most prior research reported cross‐sectional associations. We aimed to fill this gap by investigating whether baseline regional cerebral vesicular acetylcholine transporter ...

The role of expertise, semantics, and learning in spatial memory

, 2012
This research investigates the mechanisms that underpin object location memory. It approaches this endeavour by examining a recently reported phenomenon of spatial memory, that of exclusivity.

An Enhanced Memory Address Mapping Scheme for Improved Memory Access Performance of 2-D DWT Processing Systems

, 2007
The implementation of the memory for storing image and transform coefficients in 2-D DWT processing systems using the more cost-effective external memory module such as DDR DRAM is shown to suffer from effective memory bandwidth which is significantly ...

Efficacy of Intermittent Theta‐Burst Stimulation for Prolonged Disorders of Consciousness: A Prospective, Randomized, Controlled Trial

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

The Influence of Direct and Indirect Speech on Source Memory [PDF]

, 2018
People perceive the same situation described in direct speech (e.g., John said, “I like the food at this restaurant”) as more vivid and perceptually engaging than described in indirect speech (e.g., John said that he likes the food at the restaurant). So,

FDG‐PET Associations With Disease Severity and Outcomes in NMDA‐Receptor IgG Autoimmune Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Patients with N‐methyl‐D‐aspartate (NMDA) receptor‐immunoglobulin G (IgG) autoimmune encephalitis (NMDAR‐IgG AE) demonstrate occipital lobe hypometabolism on baseline brain fluorodeoxyglucose‐positron emission tomography (bFDG‐PET).

Reducing main memory access latency through SDRAM address mapping techniques and access reordering mechanisms

, 2006
As the performance gap between microprocessors and memory continues to increase, main memory accesses result in long latencies which become a factor limiting system performance.
