(Medical Xpress) -- One of the many potential consequences of ischemic stroke a lesion, or localized pathological change in the brain, in which blood flow insufficient to meet metabolic demand leads to poor oxygen supply (cerebral hypoxia) is compromise to two different visual plasticity paradigms: sensory learning (the enhancement of visual acuity and contrast sensitivity of the open eye after monocular deprivation, or MD, in which vision in one eye is blocked) and ocular dominance, or OD, plasticity (a shift in the ocular dominance of neurons in the binocular part of the visual cortex toward the open eye after MD). A standard view holds that changes in the activity of the major thalamocortical afferents to the visual cortex (the afferents from the left and right eye) are sufficient to induce OD-plasticity.
