Longitudinal modeling of age-related memory decline and the APOE epsilon4 effect.
14 Jul 2009 
BACKGROUND: The APOE epsilon4 allele is associated with the risk of late-onset Alzheimer's disease. The age at which memory decline diverges among persons who are homozygous for the APOE epsilon4 allele, those who are heterozygous for the allele, ...

Cognitive function in Japanese centenarians according to the Mini-Mental State Examination.
13 Jul 2009 BACKGROUND/AIMS: We examined the effect of aging on cognitive function at the limit of human life expectancy by characterizing state of cognition in centenarians without clinical cognitive impairment. METHODS: Participants were 68 centenarians ...

Stress and corticosterone enhance cognitive recovery from hippocampal stroke in rats.
12 Jul 2009 When locally infused, the potent vasoconstrictor, endothelin-1 (ET-1) produces partial ischemic damage in many regions of the brain, including the hippocampus. The hippocampus is known for a high density of glucocorticoid receptors and for the ...

Segmented-memory recurrent neural networks.
12 Jul 2009 Conventional recurrent neural networks (RNNs) have difficulties in learning long-term dependencies. To tackle this problem, we propose an architecture called segmented-memory recurrent neural network (SMRNN). A symbolic sequence is broken into ...

Learning and memory: how sea slug behaviors become compulsive.
12 Jul 2009 A recent study of how food-seeking behavior in the sea slug Aplysia becomes compulsive provides new insights into the neural mechanisms of operant ...

10 Jul 2009 Individuals time as if using a stopwatch that can be stopped or reset on command. Here, we review behavioural and neurobiological data supporting the time-sharing hypothesis that perceived time depends on the attentional and memory resources ...

Transthyretin knockout mice display decreased susceptibility to AMPA-induced neurodegeneration.
8 Jul 2009 Transthyretin (TTR) has been regarded as a neuroprotective protein given that TTR knockout (KO) mice display increased susceptibility for amyloid beta deposition and memory deficits during aging. In parallel, TTR KO mice have increased levels of ...

8 Jul 2009 Most bidirectional associative memory (BAM) networks use a symmetrical output function for dual fixed-point behavior. In this paper, we show that by introducing an asymmetry parameter into a recently introduced chaotic BAM output function, prior ...

Combinational chelation therapy abrogates lead-induced neurodegeneration in rats.
8 Jul 2009 Lead, a ubiquitous and potent neurotoxicant causes oxidative stress which leads to numerous neurobehavioral and physiological alterations. The ability of lead to bind sulfhydryl groups or compete with calcium could be one of the reasons for its ...

Glial ephrin-A3 regulates hippocampal dendritic spine morphology and glutamate transport.
8 Jul 2009 Increasing evidence indicates the importance of neuron-glia communication for synaptic function, but the mechanisms involved are not fully understood. We reported that the EphA4 receptor tyrosine kinase is in dendritic spines of pyramidal neurons of ...
