In the auditory cortex, synaptic inhibition is known to be involved in shaping receptive fields, enhancing temporal precision, and regulating gain. Cortical inhibition is provided by local GABAergic interneurons, which comprise 10-20% of the cortical population and can be separated into numerous subclasses. The morphological and physiological diversity of interneurons suggests that these differ...

Parvalbumin (PV)-expressing inhibitory interneurons are the most numerous GABAergic interneuron type in the neocortex and hippocampus (HPC). Selective reductions in PV interneurons are observed in cortical and limbic regions in postmortem human schizophrenic brain tissue. Reductions in PV expression are also observed in rodents following acute and/or chronic treatment with NMDAantagonists (e.g....

Mutations in the thyroid hormone receptor beta (TRbeta) gene result in resistance to thyroid hormone. However, it is unknown whether mutations in the TRalpha gene could lead to a similar disease. To address this question, we prepared mutant mice by targeting mutant thyroid hormone receptor kindred PV (PV) mutation to the TRalpha gene locus by means of homologous recombination (TRalpha1PV mice)....

Solar photovoltaic (PV) arrays are providing an increasing fraction of global electrical demand, with an accelerating rate of new installations. Most of these employ conventional glass-fronted panels, but this type of PV array does not satisfy applications that require a light-weight, flexible PV generator. An option discussed in this article is to consider textiles for such solar cell substrat...

INTRODUCTION The significance of intermittent tachycardia within a pulmonary vein (PV) during an episode of atrial fibrillation (AF) is unclear. The aim of this study was to determine the role that intermittent PV tachycardias play in AF. METHODS AND RESULTS In 56 patients with AF, segmental ostial ablation guided by PV potentials was performed to isolate the PVs. The characteristics of inter...

The principle sPHPb (PV (α)) states that no oracle circuit can compute a surjection of a onto b. We show that sPHP P (a)(PV (α)) is independent of PV1(α)+ sPHP π(a) Π(a)(PV (α)) for various choices of the parameters π, Π, %, P . We also improve the known separation of iWPHP(PV ) from S 2 + sWPHP(PV ) under cryptographic assumptions.

In this paper, we prove that S 2 can prove consistency of PV−, the system obtained from Cook and Urquhart’s PV [3] by removing induction. This apparently contradicts Buss and Ignjatović [2], since they prove that PV 6⊢ Con(PV−). However, what they actually prove is unprovability of consistency of the system which is obtained from PV− by addition of propositional logic and BASICe-axioms. On the ...

Plasmalemma vesicle protein-1 (PV-1) is an integral membrane protein associated with endothelial cell caveolae and fenestrae. Since endocrine glands are enriched with fenestrated endothelium, we examined the distribution of PV-1 mRNA and protein in endocrine glands and determined its cellular localization. A single transcript was detected by RT-PCR in all endocrine glands examined. A synthetic ...

The dual cascade of enstrophy and energy in quasi-two-dimensional turbulence strongly suggests that a viscous but otherwise potential vorticity (PV) conserving system decays selectively toward a state of minimum potential enstrophy. We derive a nonperturbative mean field theory for the dynamics of minimum enstrophy relaxation by constructing an expression for PV flux during the relaxation proce...
