Decreased anterior cingulate volume in combat-related PTSD

Background Neuroanatomical data point to functional relationships between the anterior cingulate cortex (ACC) and subcortical centers regulating fear, in particular, the amygdala. Functional brain imaging has disclosed divergent patterns of ACC activation ...

Altered neocortical microcircuitry in the valproic acid rat model of autism

Tania Rinaldi

Autism is a wide-spectrum disorder with early childhood onset, affecting general cognitive capabilities and, in particular, complex information processing. Although interesting directions of research start to appear, the precise causes of the disorder and ...

Anosognosia for motor and sensory deficits after unilateral brain damage: a review

Roberta Ronchi, Giuseppe Vallar

PURPOSE: The syndrome of unawareness (anosognosia) for sensory and motor neurological deficits (hemiplegia, hemianaesthesia, and hemianopia), contralateral to the side of a hemispheric lesion, is reviewed. CONTENT: Main topics include: basic historical fac ...

Ion scattering simulations of the Si(100)-SiO2 interface

Alfredo Pasquarello, Angelo Bongiorno

We carry out ion scattering simulations to investigate the nature of the transition region at the Si(100)-SiO2 interface. Ion scattering experiments performed in the channeling geometry provide us with a genuine interfacial property, the excess Si yield, r ...

Acute stress-induced impairment of spatial memory is associated with decreased expression of neural cell adhesion molecule in the hippocampus and prefrontal cortex

Maria del Carmen Sandi Perez

BACKGROUND: There is an extensive literature describing how stress disturbs cognitive processing and can exacerbate psychiatric disorders. There is, however, an insufficient understanding of the molecular mechanisms involved in stress effects on brain and ...

Self-organization of spatial solitons

Demetri Psaltis, Ye Pu

We present experimental results on the transverse modulation instability of an elliptical beam propagating in a bulk nonlinear Kerr medium, and the formation and self-organization of spatial solitons. We have observed the emergence of order, self organizat ...

Electronic and structural evidences for charge transfer and localization in iodine-doped pentacene

Frank Nüesch, Libero Zuppiroli, Robin Humphry-Baker, Philippe Bugnon

We have investigated the doping mechanism of pentacene with iodine and its impact on the structure and on the electronic properties of single crystals, powders, and thin films in a large range of iodine concentration up to six iodine per pentacene (PEN) mo ...

Correlation between modulation and structural disorder in the 4,4 '-diethoxyazoxybenzene

Gervais Chapuis, Philip Pattison

The structural refinement of the modulated phase of 4,4'-Diethoxyazoxybenzene (DXB) indicates a correlation between the shifts on the DXB molecule (modulation) and the probability to find the azoxy (N --> O) group in different configurations (disorder). Th ...

Determining the structure of semiconductor heterointerfaces by excitonic optical spectra

Vincenzo Savona

A combined theoretical and experimental analysis of the resonant Rayleigh scattering by excitons in a disordered GaAs quantum well with monolayer islands is reported. Experimentally, the coherent resonant Rayleigh scattering is deduced by means of both sta ...

Exciton relaxation and level repulsion in GaAs/AlxGa1-xAs quantum wires

Benoît Marie Joseph Deveaud, Vincenzo Savona, Andrea Crottini, Marc-André Dupertuis, Andrea Feltrin, Reda Idrissi Kaitouni, Xiao Wang

V groove GaAs/AlGaAs quantum wires are investigated by spatially resolved photoluminescence spectroscopy using a low-temperature scanning near- field optical microscope. The spectra along the wires feature several sharp emission lines, which are understood ...
