Inhibition of Return in the visual field [PDF]

open access: yes, 2013
Inhibition of return (IOR) as an indicator of attentional control is characterized by an eccentricity effect, that is, the more peripheral visual field shows a stronger IOR magnitude relative to the perifoveal visual field.

Statistical process control to monitor use of a web‐based autoplanning tool

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose To investigate the use of statistical process control (SPC) for quality assurance of an integrated web‐based autoplanning tool, Radiation Planning Assistant (RPA). Methods Automatically generated plans were downloaded and imported into two treatment planning systems (TPSs), RayStation and Eclipse, in which they were recalculated using ...

Spectacles with highly aspherical lenslets for myopia control do not change visual sensitivity in automated static perimetry

open access: yesFrontiers in Neuroscience, 2022
PurposeSpectacle lenses with arrays of lenslets have gained popularity in myopia control due to their high efficacy, low impact on visual performance, and non-invasiveness.

Treatment planning with a 2.5 MV photon beam for radiation therapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose The shallow depth of maximum dose and higher dose fall‐off gradient of a 2.5 MV beam along the central axis that is available for imaging on linear accelerators is investigated for treatment of shallow tumors and sparing the organs at risk (OARs) beyond it.

Association of Ultrapure Citicoline, Homotaurine and Vitamin E in the Management of Normotensive Glaucoma: A Case Report

open access: yesCase Reports in Ophthalmology, 2020
Normal tension glaucoma (NTG) remains a therapeutic challenge for the ophthalmologist since there are no effective therapies as the main therapeutic target, i.e., the intraocular pressure (IOP) increase, is missed.

Diversity and evolution of optically complex eyes in a family of deep-sea fish: Ocular diverticula in barreleye spookfish (Opisthoproctidae)

open access: yesFrontiers in Ecology and Evolution, 2022
Several families of mesopelagic fish have tubular eyes that are usually upwardly directed. These maximise sensitivity to dim downwelling sunlight and dorsal bioluminescence, as well as facilitating the detection of dark silhouettes above the animal. Such

Visual Field Prediction using Recurrent Neural Network

open access: yesScientific Reports, 2019
Artificial intelligence capabilities have, recently, greatly improved. In the past few years, one of the deep learning algorithms, the recurrent neural network (RNN), has shown an outstanding ability in sequence labeling and prediction tasks for ...

Feedback Generates a Second Receptive Field in Neurons of Visual Cortex

open access: yesNature, 2020
Animals sense the environment through pathways that link sensory organs to the brain. In the visual system, these feedforward pathways define the classical feedforward receptive field (ffRF), the area in space in which visual stimuli excite a neuron 1 ...

The time course of spatial attention shifts in elementary arithmetic [PDF]

open access: yes, 2017
It has been proposed that elementary arithmetic induces spatial shifts of attention. However, the timing of this arithmetic-space association remains unknown. Here we investigate this issue with a target detection paradigm. Detecting targets in the right
