Probing the architecture of visual number sense with parietal tRNS [PDF]

open access: yesCortex, 2019
Theoretical accounts of the visual number sense (VNS), i.e., an ability to discriminate approximate numerosities, remain controversial. A proposal that the VNS represents a process of numerosity extraction, leading to an abstract number representation in the brain, has been challenged by the view that the VNS is non-numerical in its essence and amounts

Value Assignments to Observables Depending on a History of Context Change [PDF]

open access: yes, 2006
The functional composition principle is generalized by taking into account of history of context change. Analysis of Peres' example shows hysteresis of value assignments.

Evaluating Aftereffects of Short-Duration Transcranial Random Noise Stimulation on Cortical Excitability

open access: yesNeural Plasticity, 2011
A 10-minute application of highfrequency (100–640 Hz) transcranial random noise stimulation (tRNS) over the primary motor cortex (M1) increases baseline levels of cortical excitability, lasting around 1 hr poststimulation Terney et al. (2008).

Improving visual functions in adult amblyopia with combined perceptual training and transcranial random noise stimulation (tRNS): a pilot study [PDF]

open access: yes, 2014
Amblyopia is a visual disorder due to an abnormal pattern of functional connectivity of the visual cortex and characterized by several visual deficits of spatial vision including impairments of visual acuity (VA) and of the contrast sensitivity function (

High-Frequency Transcranial Random Noise Stimulation for Auditory Hallucinations of Schizophrenia: A Case Series

open access: yesBiomedicines, 2022
Transcranial electrical stimulation has been proposed as a noninvasive therapeutic approach for reducing treatment-resistant symptoms of schizophrenia—in particular, auditory hallucinations. However, the high variability observed in the clinical response

Molecular phylogeny and diversification history of Prosopis (Fabaceae: Mimosoideae) [PDF]

open access: yes, 2008
The genus Prosopis is an important member of arid and semiarid environments around the world. To study Prosopis diversification and evolution, a combined approach including molecular phylogeny, molecular dating, and character optimization analysis was ...

Non-supersymmetric D-Brane Configurations with Bose-Fermi Degenerate Open String Spectrum [PDF]

open access: yes, 1999
The spectrum of open strings on various non-BPS D-brane configurations in type II string theory on a K3 orbifold is analysed. At a generic point in the corresponding moduli space the spectrum of open strings does not have any degeneracy between bosonic ...

Network unfairness in dragonfly topologies [PDF]

open access: yes, 2016
Dragonfly networks arrange network routers in a two-level hierarchy, providing a competitive cost-performance solution for large systems. Non-minimal adaptive routing (adaptive misrouting) is employed to fully exploit the path diversity and increase the ...

Covariant Map Between Ramond-Neveu-Schwarz and Pure Spinor Formalisms for the Superstring [PDF]

open access: yes, 2014
A covariant map between the Ramond-Neveu-Schwarz (RNS) and pure spinor formalisms for the superstring is found which transforms the RNS and pure spinor BRST operators into each other.
