  * Describe visual information processing.
  * Explain two conditions that impair visual information processing.
  * Discuss current trends in the research of visual information processing and how they advance understanding of visual information processing.

Visual Information Processing
Visual information processing refers to the visual cognitive skills that allow us to process and interpret meaning from the visual information that we gain through our eye sight. Visual perception plays an important role in spelling, mathematics, and reading. The visual system is exclusive as much of visual processing occurs outside the brain within the retina of the eye. The light-sensitive receptors of the eye convert the image projected onto the retina into spatially distributed neural activity in the first neurons of the visual pathway. Within the retina, the receptors synapse with bipolar and horizontal cells, which establish the basis for brightness and color contrasts. In turn, the bipolar cells synapse with retinal ganglion cells and amacrine cells, which improve contrast effects that support form vision and establish the basis for movement detection. The information from the eye is carried by the axons of the retinal ganglion cells to the midbrain and diencephalon.

Conditions That Impair Visual Information Processing.
Acute Hypoglycemia
This affects adults with the disease of diabetes mellitus type I. it causes general impairment in cognitive performance. Acute hypoglycemia has been shown to impair visual information processing in non diabetic human subjects.
Acquired Brain Injury
Another condition that can impair...
