Mind the gap: binding experiences across space and time in the human hippocampus.
28 Jul 2009 
A fundamental goal in memory research is to understand what class of learning problem the hippocampus is uniquely designed to solve. While much controversy surrounds the particular types of memories the hippocampus is thought to support, one ...

Feature- and order-based timing representations in the frontal cortex.
28 Jul 2009 We examined activity in the frontal cortex as monkeys performed a duration-discrimination task. Two stimuli, one red and the other blue, appeared sequentially on a video screen--in either order. Later, both stimuli reappeared, and to receive a ...

28 Jul 2009 The entorhinal cortex (EC) is regarded as the gateway to the hippocampus and thus is essential for learning and memory. Whereas the EC expresses a high density of GABA(B) receptors, the functions of these receptors in this region remain unexplored. ...

Amyloid + activation = Alzheimer's?
28 Jul 2009 PET imaging of Alzheimer's disease (AD) patients demonstrates Abeta-protein accumulation in a default mode network. In this issue of Neuron, Sperling and colleagues show that cognitively intact individuals with Abeta in this network fail to ...

27 Jul 2009 OBJECTIVE: Cerebral inflammatory reaction is discussed as a contributor to adverse cerebral outcome after cardiac surgery with cardiopulmonary bypass. This study was designed to determine the effect of cardiopulmonary bypass on both cerebral ...

27 Jul 2009 BACKGROUND: The neonatal brain is particularly vulnerable to imbalances in redox homeostasis because of rapid growth and immature antioxidant systems. Vitamin C has been shown to have a key function in the brain, and during states of deficiency it ...

27 Jul 2009 Iron deficiency (ID) is the most prevalent worldwide nutritional deficiency. Groups at risk of developing ID anemia are infants and pregnant women, even in industrialized countries. Our goal in this study was to evaluate the long-term consequences ...

27 Jul 2009 Here, we examine the role of the magnitude of the unconditioned stimulus (US) during classical conditioning in consolidation processes after memory retrieval. We varied the US durations during training and we test the impact of these variations on ...

26 Jul 2009 A widely used complex-valued activation function for complex-valued multistate Hopfield networks is revealed to be essentially based on a multilevel step function. By replacing the multilevel step function with other multilevel characteristics, we ...

The diagnostic utility of multiple-level likelihood ratios.
26 Jul 2009 Clinicians are accustomed to interpreting diagnostic test scores in terms of sensitivity and specificity. Many clinicians also appreciate that sensitivity and specificity need to be interpreted in terms of local base rates (i.e., pretest ...
