From threat to fear: the neural organization of defensive fear systems in humans.
28 Sep 2009 
Postencounter and circa-strike defensive contexts represent two adaptive responses to potential and imminent danger. In the context of a predator, the postencounter reflects the initial detection of the potential threat, whereas the circa-strike is ...

28 Sep 2009 For social beings like humans, detecting one's own and others' errors is essential for efficient goal-directed behavior. Although one's own errors are always negative events, errors from other persons may be negative or positive depending on the ...

Color-related signals in the primate superior colliculus.
28 Sep 2009 Color is important for segmenting objects from backgrounds, which can in turn facilitate visual search in complex scenes. However, brain areas involved in orienting the eyes toward colored stimuli in our environment are not believed to have access ...

Adenylyl cyclase type 5 contributes to corticostriatal plasticity and striatum-dependent learning.
28 Sep 2009 Dopamine (DA)-dependent corticostriatal plasticity is thought to underlie incremental procedural learning. A primary effector of striatal DA signaling is cAMP, yet its role in corticostriatal plasticity and striatum-dependent learning remains ...

23 Sep 2009 Readers acquire information outside the current eye fixation. Previous research indicates that having only the fixated word available slows reading, but when the next word is visible, reading is almost as fast as when the whole line is seen. ...

22 Sep 2009 This study investigated metaphor comprehension in the broader context of task-difference effects and manipulation of processing difficulty. We predicted that right hemisphere recruitment would show greater specificity to processing difficulty rather ...

Tracking the emergence of conceptual knowledge during human decision making.
22 Sep 2009 Concepts lie at the very heart of intelligence, providing organizing principles with which to comprehend the world. Surprisingly little, however, is understood about how we acquire and deploy concepts. Here, we show that a functionally coupled ...

Spatial attention decorrelates intrinsic activity fluctuations in macaque area V4.
22 Sep 2009 Attention typically amplifies neuronal responses evoked by task-relevant stimuli while attenuating responses to task-irrelevant distracters. In this context, visual distracters constitute an external source of noise that is diminished to improve ...

Confidence and corrections: how we make and un-make up our minds.
22 Sep 2009 Single neurons in several brain areas intervening between sensation and action signal the accumulation of sensory evidence favoring a particular behavioral response. Two new studies show that these same neurons encode decision confidence and that ...

Cognitive change effects in a semantic, a numeric, and a figure inference task.
21 Sep 2009 Event-related potentials were recorded to examine the electrophysiologic correlates of the evaluation of possible answers provided during a semantic, a numeric, and a figure inference task. We examined two conditions: the probe stimulus given was ...
