Temporal properties of visual perception upon electrical stimulation of the retina
Purpose: To investigate the elementary temporal properties of electrically evoked percepts in blind patients chronically implanted with an epiretinal prosthesis. Methods: Nine subjects were presented with isolated stimuli of variable duration and pulse rate. Stimulation amplitude was set to the upper comfortable level and a group of 2x2 adjacent electrodes was simultaneously activated. First, s...

Background & Aims: Direct electrical stimulation of the brain is a therapeutic technique that can be effective in improving visual, verbal, and spatial perception. The present study investigated the effect of direct electrical stimulation (tDCS) of the posterior parietal cortex on improving spatial, visual, and verbal perceptual abilities. Materials & Methods: In this quasi-experimental study,...

متن کاملPattern electrical stimulation of the human retina
Experiments were conducted to study if electrical stimulation of the retinal surface can elicit visual sensation in individuals blind from end-stage retinitis pigmentosa (RP) or age-related macular degeneration (AMD). Under local anesthesia, different stimulating electrodes were inserted through the eyewall and positioned over the surface of the retina. Subjects' psychophysical responses to ele...

The purpose of this study was to investigate the development of two variables of memory and visual perception. For this purpose, 129 pre-primary, elementary and 3rd grade elementary school students were selected by available sampling method. The female students in this study were 69 and the male students were 60. The development of perceptual and visual memory of these students was measured usi...
