Band-edge-induced Bragg diffraction in two-dimensional photonic crystals [PDF]
, 2006 Two-dimensional photonic crystals composed of two orthogonal volume diffraction gratings have been photogenerated in photopolymers. When the read beam is set at the Bragg angle, the diffraction efficiency of the transmission grating is strongly enhanced ...

Local control of striatal dopamine release
Frontiers in Behavioral Neuroscience, 2014 The mesolimbic and nigrostriatal dopamine (DA) systems play a key role in the physiology of reward seeking, motivation and motor control. Importantly, they are also involved in the pathophysiology of Parkinson’s and Huntington’s disease, schizophrenia ...

DELIRIUM FROM THE GLIOCENTRIC PERSPECTIVE
Frontiers in Cellular Neuroscience, 2015 Delirium is an acute state marked by disturbances in cognition, attention, memory, perception, and sleep-wake cycle which is common in elderly. Others have shown an association between delirium and increased mortality, length of hospitalization, cost ...

A New Method to Measure the Post-Reionization Ionizing Background from the Joint Distribution of Lyman-$\alpha$ and Lyman-$\beta$ Forest Transmission [PDF]
, 2017 The amplitude of the ionizing background that pervades the intergalactic medium (IGM) at the end of the epoch of reionization provides a valuable constraint on the emissivity of the sources which reionized the Universe. While measurements of the ionizing

Frontiers in Psychology, 2013 This work aims at presenting some hypotheses about the potential neurobiological substrate of imagery and imagination. For the present purposes, we will define imagery as the production of mental images associated with previous percepts, and imagination ...

Frontiers in Physiology, 2012 We review the evidence of exocytosis from extrasynaptic sites in the soma, dendrites and axonal varicosities of central and peripheral neurons of vertebrates and invertebrates, and how it may contribute to signaling in the nervous system.

EBIC/TEM investigations of process-induced defects in EFG silicon ribbon [PDF]
, 1981 Electron bombardment induced conductivity and scanning transmission electron microscopy observations on unprocessed and processed edge-defined film-fed growth ribbon show that the phosphorus diffused junction depth is not uniform, and that a variety of ...

Dopaminergic transmission in the rat retina: evidence for volume transmission
Journal of Chemical Neuroanatomy, 1996 The study was designed to determine whether dopaminergic neurotransmission in the retina can operate via volume transmission. In double immunolabelling experiments, a mismatch as well as a match was demonstrated in the rat retina between tyrosine hydroxylase (TH) and dopamine (DA) immunoreactive (ir) terminals and cell bodies and dopamine D2 receptor ...
