Psychophysical evidence for two routes to suppression before binocular summation of signals in human vision [PDF]
, 2007 Visual mechanisms in primary visual cortex are suppressed by the superposition of gratings perpendicular to their preferred orientations. A clear picture of this process is needed to (i) inform functional architecture of image-processing models, (ii ...

New species and new records in Agarista (Ericaceae) from the Peruvian Andes
Nordic Journal of Botany, EarlyView.Agarista (Ericaceae) is currently represented in Peru by three species. Here, we update this number to five, adding new taxa based on the recognition of a taxonomic novelty and new records. The new species Agarista eugeniifolia differs from all congeneric species by an abaxially sulcate midvein.

NEW OBSERVATIONS ON THE ANATOMY OF THE FOSSIL CALCAREOUS ALGA SUBTERRANIPHYLLUM ELLIOTT
Rivista Italiana di Paleontologia e Stratigrafia, 2000 New specimens of Subterraniphyllum thomasii Elliott collected from the Oligocene Molare Formation outcropping close to Alessandria (northern Italy) and studied in thin sections and by SEM showed that primary pit-connections, cell fusions, uniporate ...

Otolaryngology–Head and Neck Surgery, EarlyView.Abstract Objective Spontaneous cerebrospinal fluid (sCSF) leaks of lateral skull base have little consensus on optimal management. We synthesized and evaluated current literature via systematic and meta‐analysis to compare the success rates and complications of the different surgical techniques for middle cranial fossa (MCF) sCSF leak repair.

Three and Four Courses of Radiation for Children with Recurrent Diffuse Intrinsic Pontine Glioma
Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Re‐irradiation (RT2) for children with diffuse intrinsic pontine glioma (DIPG) is increasingly used upon recurrence; however, limited data are available for evaluating additional courses of radiotherapy (RT) for DIPG. The purpose of this case series was to report our institutional experience in treating patients with recurrent DIPG ...

Temporal Dynamics of Binocular Disparity Processing with Corticogeniculate Interactions [PDF]
, 1999 A neural model is developed to probe how corticogeniculate feedback may contribute to the dynamics of binocular vision. Feedforward and feedback interactions among retinal, lateral geniculate, and cortical simple and complex cells are used to simulate ...

The Current Situation and Development of Endoscopic Ear Surgery in China
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Endoscopic ear surgery has been widely performed in China since 2015 due to the development and rapid popularization of endoscopic technology. Due to the relative shortness of the auditory meatus, only a fixed endoscope is required in many cases, rather than a motion similar to a nasal endoscope, and uncontrollable bleeding is virtually non ...

Modeling the Possible Influences of Eye Movements on the Refinement of Cortical Direction Selectivity [PDF]
, 2004 The second-order statistics of neural activity was examined in a model of the cat LGN and V1 during free-viewing of natural images. In the model, the specific patterns of thalamocortical activity required for a Bebbian maturation of direction-selective ...

Morphometric analyses of the visual pathways in macular degeneration
, 2014 Introduction. Macular degeneration (MD) causes central visual field loss. When field defects occur in both eyes and overlap, parts of the visual pathways are no longer stimulated.
