Binocular information acquisition and visual memory.

Sensory and cognitive components of visual information acquisition.

The authors describe a theory of visual information acquisition and visual memory. The theory has 2 major components. First, the visual system's initial sensory response to a short-duration, low-contrast stimulus is generated by a linear, low-pass temporal filter that operates on the stimulus's temporal waveform. Second, information is acquired from a stimulus through an independent-sampling pr...

تاثیر هم افزایی دوچشمی بر مولفه های موج پتانسیل برانگیخته بینایی

  Background : To determine the effect of binocular summation on the time domain transient VEP wave's components.   Methods : The monocular and binocular transient visual evoked potentials of 21 normally vision volunteers 18 to 24 years (mean ± SD, 20.7 ± 1.9) during a reversing checkerboard stimulus with spatiotemporal frequency of 2.18-4 cpd-Hz were recorded. The amplitude and latency of N75,...

The Effect of Drug Abstinence Program on Memory Functioning of Heroin Addicts

Introduction: Most of our knowledge regarding the link between opioid dependence and poor cognitive functioning is derived from cross sectional studies.This longitudinal study measured the change in memory functioning following complete abstinence among individuals with heroin dependence. Methods: Using a before-after design,this study followed 30 adults ...

Does whole body exposure to GSM-950 MHz electromagnetic fields affect acquisition and consolidation of spatial information in rats?

Background: This study was planned to examine the effects of whole-body exposure to GSM-950 MHz electromagnetic fields (EMFs) on acquisition and consolidation of spatial memory in rats using a water maze task. Materials and Methods: In experiment 1, the animals were given two blocks of five trials per day for three consecutive days in a water maze task. The interval between blocks was 4h...
