This could be done by measuring the visual parameters of the landscape using photographs, but there are currently no standard procedures as to how to do this.
We investigated the mechanisms of hallucinogen-induced visions by measuring the visual and perceptual effects of the hallucinogenic serotonin 5-HT2AR receptor agonist and monoamine releaser, 3,4-methylenedioxyamphetamine (MDA), in a double-blind placebo-controlled study.
The assessment of clinical results was performed by measuring the numeric visual analogue scale (0 10) of low back pain and the Korean Oswestry Disability Index on the preoperative hospital days, the second postoperative week, the sixth postoperative month, and the first postoperative year.
The aim of this study was to compare the temporal features of multisensory integration in twenty obese people to those of twenty healthy controls, by measuring the audio-visual temporal binding window, defined as the range of stimulus onset asynchrony in which multiple sensory inputs have a high probability of altering responses.
Vertical density (an index of biomass) [56] was quantified by measuring the minimum height of visual obstruction from 4m in each cardinal direction from a Robel pole at a height of 1m [57].
NVC has been assessed as the regulation of blood flow to the visual cortex by measuring the increase in blood flow of the posterior cerebral artery (PCA) in response to a given visual stimulation, as evaluated using transcranial Doppler (TCD) ultrasound [ 1].
Isolated RNA was resuspended in The RNA Storage Solution (Ambion Inc., Austin, TX), quantified (A260), and assessed for purity by measuring the A260/A280 ratio and by visual inspection of 1.0 μg on a denaturing gel.
There is evidence that the visual function of BRVO patients after treatment of macular edema is not fully described by measuring visual acuity: 1) Subjects with good visual acuity sometimes have difficulty seeing certain objects and the opposite also occurs[ 9]. 2) In some BRVO patients, there is no improvement of visual acuity after improvement of macular edema and SRD[ 22- 24].
In this study, we explore the balance between inhibition and excitation in migraine by measuring visual performance for a well-studied perceptual analogue of centre-surround neuronal responses: the Chubb illusion (also referred to as contrast-contrast suppression) [33].
Study design: In a randomised, 3 cycle, placebo-controlled study, neurovisual transmission in optic pathways were evaluated by measuring visual evoked potentials (VEP).
To measure the effects of macular pucker (MP) on macular structure and quantify function by measuring visual acuity (VA), contrast sensitivity (CS), and distortions.
