For more information go to Visual Pathways.
This side view of the visual pathways depicts their structure even more clearly.
Br The visual evoked potential(VEP)is an electro-diagnostic technique that allows assessment of visual pathways.
Visual pathways transfer information through different neural pathways. .
At all levels of transfer and processing in the visual pathways there are parallel functions.
These findings were expected,considering that the luminance of the monitor screen is an important factor in assessing the visual pathways.
As the movement of the ocular globe,the integrity of the visual pathways is a pre-requisite for the development of reading and writing.
So, to explain this curious disorder, we look at the structure andfunctions of the normal visual pathways in the brain.
If you keep this picture of the visual pathways in your memory when you assess visual functions you remember to observe the many parallel visual functions.
If an infant has unusual eye movements, nystagmus or strabismus,the eyes and the visual pathways need to be examined.
In the optic nerves and visual pathways there are several different types of nerve fibres, of which the magnocellular and the parvocellular pathway are the most important.
This study aimed to develop a prototype for monitoring the vep to assess the integrity of the visual pathways during neurophysiological surgeries.
With these slides on the structure of the visual pathways I wish to create an awareness on the multitude of functions that we need to observe and measure, not only visual acuity.
The effects of tdcs on visual performance are still poorly understood and specificity of the visual pathways and functions affected by stimulation was not yet investigated.
The methodology used in this study allowed to obtain potential similar to those described in other studies, with little variability, andis useful for evaluation of animals with suspected changes in the central visual pathways.
Violations of visual functions appear when a visual analyzer and visual pathways located in the occipital lobe of the brain are affected.
In the case of the light source, when its intensity is increased, the intensity of scattered light also increases in the retina, a phenomenon known as"light curtain" veiling light or light cascading effect, since the scattered light appears in one eye form of veil or cascade, whereas in the case of the eye,any change in the visual pathways that impede or alter the light path can cause an increase in the dispersion.
This loop and several other features of the visual pathways function as an effective filter inhibiting parts of visual information from getting into the higher cortical functions.
At birth there is a structuring of the macular area, which was previously similar to the peripheral retina, andthe development of the afferent and efferent visual pathways takes place, with neural connections through the dendrites.
Studies have shown a correlation between the auditory processing, visual pathways and expressive language disorders which can cause speech fluency problems characterized as stuttering.
The quality of the incoming visual information. Its quality can be affected by changes in structures of the eyes, the optic nerves,the long visual pathways or because of irregular oculomotor functions.
Studies have shown that there is a correlation between the processing of auditory information, visual pathways, and expressive language difficulty, which can affect speech fluency and be characterized as stuttering.
We show that there is already a reduction in visual function in men who are only carriers of the gene for the disease Sadun et al. 2004; Ventura et al. 2005a; Ventura et al., 2005b, andthat there are specific visual pathways affected while others remain functionally normal Gualtieri et al., 2004, Gualtieri et al., 2008, Ventura et al., 2007.
It is the continuation of the VISUAL PATHWAY that conveys the visual information originally from the RETINA to the optic chiasm via the OPTIC NERVES.
An attempt to localize structures in the primary visual pathway was completed by Szikla and colleagues.
The visual evoked potential(vep) evaluates the function andintegrity of cortical and subcortical structures of the visual pathway.
These properties have led it to becoming the most important diagnostic tool for early diagnosis andfollow-up for disorders involving the front part of the visual pathway.
For those who study the visual system,no one could say that the visual pathway was undesrtood and described if we can¿t foresee its activity.
These can be used to verify that the problem is indeed due to a malfunction of the visual cortex and/or the posterior visual pathway.
The displacement of the maximum sensitivity to lower frequencies can be related to the functioning of the magnocellular visual pathway, which is specialized in processing low spatial frequencies Benedek, Benedek, Keri,& Janáky, 2003; Ellemberg, Lewis, Liu,& Maurer, 1999.
