All Feathers and Attitude
… how memories, culture, work, place, family, and brain chemistry simultaneously create and undermine a sense of self. How the sense of self is not contiguous, or smooth. How hope and regret wrestle.</p> <p>While deeply personal, <em>All Feathers and Attitude</em> is not a memoir, but rather an …

Association of Maternal Cumulative Risk during Pregnancy and IQ in Preschoolers: Role of Glucocorticoids and their Receptors
… during pregnancy disrupt developing fetal brain chemistry and architecture, resulting in later memory and learning deficiencies. While we know that the quality of the fetal environment and the timing of exposure to a variety of substances are critical for developmental and health outcomes, …

Functional Magnetic Resonance Spectroscopy in First-Episode Schizophrenia: Measuring Glutamate and Glutathione Dynamics at 7-Tesla
… provides a non-invasive means to observe in-vivo brain chemistry, including glutamate and glutathione. By adding a functional component to an MRS paradigm (fMRS), such as the color-word Stroop task, it is possible to detect potential changes in brain metabolite levels in response to a cognitive …

Mid-Infrared Integrated Devices for Optical Chemical Sensing
… a novel method for continuous monitoring of the brain chemistry of traumatically brain-injured patients by MIR transmission spectroscopy. Here, the outlet of a cerebral microdialysis catheter is cou- pled to a micro flow-cell and the flowing microdialysate is continuously analysed. Clinical …

Is Talk Cheap in High Stake Trust Games? An Experimental Analysis of Decentralized Cooperation
… practice. In this study, we measured changes in brain chemistry via peripheral blood draws and related these to participants’ states after 20 minutes of group meditation. Those who meditated had a reduction in the stress hormone ACTH. Further, smaller groups reduced ACTH more effectively than …

The psychopharmacogenetics of ethanol and its relation to brain catecholamines
… which have been demonstrated between alcohol and brain catecholamines. The evidence is considered under five areas of study; 1.) the effects of ethanol on brain catecholamine levels and turnover; 2.) ethanol’s action on brain cyclic 3′, 5′-adenosine monophosphate; 3.) the correlation between …

Drug recovery in paediatric tuberculous meningitis
… especially because penetration across the blood-brain barrier (BBB) has been difficult to study. Rifampicin (RIF) is a leading drug in the management of TBM but concentrations in ventricular cerebrospinal fluid (VCSF) have not been studied in TBM patients, and emerging evidence suggests that …

Monitoring brain neurochemistry after brain trauma
… monitoring of cerebral metabolites in traumatic brain injury (TBI) patients. Through a series of in-vitro and in-vivo studies, this research addresses the critical need for enhanced sensitivity and specificity in brain metabolite monitoring. The integration of these sensors with existing clinical …

Fabrication and testing of silicon integrated nanofluidic channels for neurochemical transport
… to study neurological activity in mammalian brains, though none of these methods fully satisfy the requirements for high-resolution neurochemical sensing. Therefore, to fulfill this need, we have developed a process to build a monolithic neurochemical sampling probe in which the size and …

Studies on the characterization of a soluble factor of a sodium-activated, magnesium-dependent adenosinetriphosphatase in rat cerebral cortex
<p>From the standpoint of physiologists, emphasis has been placed on viewing the chemical nature of the membrane as an operational barrier to the free diffusion of ions. This tends to explain the fact that the ionic composition of the cytoplasm of the animal cell differs from its external fluid …

The effects of the kappa agonist U-50,488 on morphine-induced place preference conditioning and Fos immunoreactivity in the preweanling and periadolescent rat
The effects of the kappa opioid agonist U-50,488 on morphine-induced condtioned place preference (CPP), locomotor activity and Fos immunoreactivity and assessed in 10-, 17- and 35-day old rats. It was predicted that kappa agonist treatment would block the unconditioned and conditioned behaviors …
