Serine proteases, serine protease inhibitors, and protease-activated receptors: roles in synaptic function and behavior.
Serine proteases, serine protease inhibitors, and protease-activated receptors have been intensively investigated in the periphery and their roles in a wide range of processes-coagulation, inflammation, and digestion, for example-have been well characterized (see Coughlin, 2000; Macf...
Caloric restriction in humans: impact on physiological, psychological, and behavioral outcomes.
We review some of the major physiological, psychological, and behavioral changes after 6 months of CR in overweight otherwise healthy volunteers. Special emphasis is given to the first completed clinical studies that have investigated the effects of controlled, high-quality energy-restricted diets o...
Abnormal parietal function in conversion paresis.
We included both normal controls and feigners to control for conversion paresis. We studied both movement execution and imagery, and we contrasted both within-group and between-group activation. Moreover, to reveal hemisphere-specific effects that have not been reported before, we performed these an...
[Genes and neurophysiological indicators of cognitive processes: a review].
This article provides an overview of the genetic association studies relating candidate genes with event-related potentials. This new and rapidly developing area may aid in elucidating the molecular basis of individual differences in cognitive abilities and broaden our knowledge ofne...
Engagement of large-scale networks is related to individual differences in inhibitory control
We pooled data over five separate fMRI studies of the Stop-signal task in order to obtain a sufficiently large sample size to robustly detect brain/behavior correlations. In addition, rather than performing mass univariate correlation analysis across all voxels, we increased statistical power by red...
5-HT1A receptor-regulated signal transduction pathways in brain
Serotonin is an influential monoamine neurotransmitter that signals through a number of receptors to modulate brain function. Among different serotonin receptors, the serotonin 1A (5-HT1A) receptors have been tied to a variety of physiological and pathological processes, notably in a...
Histone deacetylases govern cellular mechanisms underlying behavioral and synaptic plasticity in the developing and adult brain.
We will discuss the latest findings on the specific or redundant roles of individual HDACs in the brain as well as the impact of HDAC function on complex behavior, with a focus on learning, memory formation, and affective behavior. Potential HDAC-mediated cellular mechanisms underlying those behavio...
Sensory exploitation and cultural transmission: the late emergence of iconic representations in human evolution.
We examine the hypothesis that demographic changes caused cultural "cumulative adaptive evolution" and as such the emergence of modern symbolic behavior. This approach usefully explains the evolution of utilitarian skills and tools, and the creation of symbols to identify groups. However, it does no...
Neural basis of extraordinary empathy and altruistic motivation
We examined the neural basis of extraordinary empathy and altruistic motivation in African-American and Caucasian-American individuals using functional magnetic resonance imaging. Our results indicate that empathy for ingroup members is neurally distinct from empathy for humankind, more generally. P...
[Serotonin now: Part 2. Behavioral genetics and psychopathology]
Several lines of evidence implicate a dysregulation of the serotonin (5-HT) system in emotional behavior and stress, and point to its relevance for the etiology and pathogenesis of various neuropsychiatric disorders. This is evidenced by behavioral pharmacology as well as genetic studies, yet the im...
