The effects of electroacupuncture on TH1/TH2 cytokine mRNA expression and mitogen-activated protein kinase signaling pathways in the splenic T cells of traumatized rats.

30 Oct 2009 BACKGROUND: Surgical trauma contributes to postoperative immune suppression, which is associated with an increased susceptibility to subsequent infections. Electroacupuncture (EA) can alleviate pain and exert immunoregulatory effects. However, the ...

Mental training enhances attentional stability: neural and behavioral evidence.

19 Oct 2009 The capacity to stabilize the content of attention over time varies among individuals, and its impairment is a hallmark of several mental illnesses. Impairments in sustained attention in patients with attention disorders have been associated with ...

Distributed and antagonistic contributions of ongoing activity fluctuations to auditory stimulus detection.

19 Oct 2009 Recent studies have shown that ongoing activity fluctuations influence trial-by-trial perception of identical stimuli. Some brain systems seem to bias toward better perceptual performance and others toward worse. We tested whether these observations ...

Proteomic analysis uncovers novel actions of the neurosecretory protein VGF in nociceptive processing.

19 Oct 2009 Peripheral tissue injury is associated with changes in protein expression in sensory neurons that may contribute to abnormal nociceptive processing. We used cultured dorsal root ganglion (DRG) neurons as a model of axotomized neurons to investigate ...

Ventral striatal neurons encode the value of the chosen action in rats deciding between differently delayed or sized rewards.

19 Oct 2009 The ventral striatum (VS) is thought to serve as a gateway whereby associative information from the amygdala and prefrontal regions can influence motor output to guide behavior. If VS mediates this "limbic-motor" interface, then one might expect ...

Task-dependent activations of human auditory cortex during pitch discrimination and pitch memory tasks.

19 Oct 2009 The functional organization of auditory cortex (AC) is still poorly understood. Previous studies suggest segregation of auditory processing streams for spatial and nonspatial information located in the posterior and anterior AC, respectively ...

Predicting the unpredictable: weighted averaging of past stimulus timing facilitates ocular pursuit of randomly timed stimuli.

19 Oct 2009 In motor control, prediction of future events is vital for overcoming sensory-motor processing delays and facilitating rapid and accurate responses in a dynamic environment. In human ocular pursuit this is so pervasive that prediction of future ...

Prostaglandin E2-induced masculinization of brain and behavior requires protein kinase A, AMPA/kainate, and metabotropic glutamate receptor signaling.

19 Oct 2009 Prostaglandin E(2) (PGE(2)) mediates the masculinization of adult sex behavior in rats in response to the surge in serum testosterone at approximately birth. Measures of behavioral masculinization correlate with a twofold increase in spinophilin ...

The differential role of motor cortex in stretch reflex modulation induced by changes in environmental mechanics and verbal instruction.

19 Oct 2009 The motor cortex assumes an increasingly important role in higher mammals relative to that in lower mammals. This is true to such an extent that the human motor cortex is deeply involved in reflex regulation and it is common to speak of ...

Relationship between neural responses and visual grouping in the monkey parietal cortex.

19 Oct 2009 Visual grouping through the binding of multiple discrete elements is an important component of object perception, and neurological studies have shown that the posterior parietal cortex plays a vital role in that process. To study the neural ...
