When asked to imagine a visual scene, such as an ant crawling on a checkered table cloth toward a jar of jelly, individuals subjectively report different vividness in their mental visualization. We show that reported vividness can be correlated with two objective measures: the early visual cortex activity relative to the whole brain activity measured by(More)
Previous studies have shown that group II metabotropic glutamate receptors (mGluRs) are present on the peripheral terminals of primary sensory neurons, suggesting that they might be involved in nociception. In this study, we investigated the modulation of nociception by peripheral group II mGluRs and the molecular basis of this modulation. Subcutaneous(More)
We previously demonstrated that activation of peripheral group II mGluRs inhibits PGE2-induced thermal hyperalgesia. In the present study we examined the role of peripheral group II mGluRs in inflammation-induced mechanical allodynia in CD1 mice. Subcutaneous injection of group II mGluR agonists or antagonists into the plantar surface of the mouse hind paw(More)
Tetrodotoxin (TTX)-resistant sodium currents are important in nociception and nociceptive sensitization, which is partially due to their cAMP/protein kinase A (PKA)-mediated enhancement. Here we studied the effects of group II mGluR activation on TTX-resistant sodium currents in cultured mouse dorsal root ganglion (DRG) neurons. Activation of adenylyl(More)
Measures of intelligence, when broadcast, serve as salient signals of social status, which may be used to unjustly reinforce low-status stereotypes about out-groups' cultural norms. Herein, we investigate neurobehavioural signals manifest in small (n = 5) groups using functional magnetic resonance imaging and a 'ranked group IQ task' where implicit signals(More)
