In this study, we investigate how the responses of the human visual pathway to temporal
frequency are modified as information transfers between the lateral geniculate nucleus …

The effect of healthy ageing on visual cortical activation is still to be fully explored. This study
aimed to elucidate whether the haemodynamic response (HDR) of the visual cortex altered …

Purpose: To detect the functional deficit of the visual cortex in anisometropic amblyopia
children using functional magnetic resonance imaging (fMRI) technique, and investigate the …

The sensitivity of the sensory systems to temporal changes of the environment constitutes
one of the critical issues in perception. In the present study, we investigated the human early …

Purpose. Functional magnetic resonance imaging (fMRI) is the most advanced
neuroimaging technique. The aim of this study was to investigate the blood oxygenation …

BACKGROUND AND PURPOSE: Myopia is a type of refractive error that blurs retinal image
and in turn can change neural signals transferred from retina to visual cortex. The purpose of …

Many studies suggest that separate retinocortical channels with different conduction speeds
transmit the information about high and low spatial frequencies (SF). Similarly, separate …

It is believed that human primary visual cortex (V1) increases activity with increasing
temporal frequency of a visual stimulus. Two kinds of visual stimulus were used in the …

Abstract Background and Aim: Optical blur due to refractive errors causes reducing retinal
image quality and induces changes in how visual system responds. The purpose of this …
