The contrast sensitivity of the cat
The Journal of Physiology, 1973 1. The experiments were carried out on pretrigeminal cats.2. By recording potentials evoked from the visual cortex by a grating stimulus, it was established that there was a linear relation between the voltage generated and the logarithm of the contrast of the grating.3.

Contrast sensitivity abnormalities in deaf individuals
Journal of Ophthalmic & Vision Research, 2018 Purpose: Hearing impaired children are heavily dependent on their sense of vision to develop efficient communication skills; any contrast sensitivity defect can negatively impact their lives because they are not able to use auditory stimuli to recognize ...

Sensitivity to Auditory Velocity Contrast [PDF]
Scientific Reports, 2016 AbstractA natural auditory scene often contains sound moving at varying velocities. Using a velocity contrast paradigm, we compared sensitivity to velocity changes between continuous and discontinuous trajectories. Subjects compared the velocities of two stimulus intervals that moved along a single trajectory, with and without a 1 second inter stimulus

Modelling contrast sensitivity of discs
Electronic Imaging, 2023 Spatial and temporal contrast sensitivities are typically measured using different stimuli. Gabor patterns are used to measure spatial contrast sensitivity and flickering discs are used for temporal contrast sensitivity. The data from both types of studies is difficult to compare as there is no well-established relationship between the sensitivity to ...

Evaluating the Use of Contrast Sensitivity Tests By Orthoptists in the UK
British and Irish Orthoptic JournalIntroduction: The importance of the use of contrast sensitivity (CS) tests in orthoptic practice is well established. However, despite the clinical relevance the implementation within clinical care is known to be variable. There are no known studies that
