Loratadine is an over-the-counter medication used to relieve symptoms due to hay fever or other allergies such as: 1  runny nose. 2  sneezing. 3  itchy, watery eyes.
Also known as the striate cortex, or simply V1, the primary visual cortex is located in the most posterior portion of the brain's occipital lobe. In fact, a large part of the primary visual cortex cannot be seen from the outside of the brain, because this cortex lies on either side of the calcarine fissure.he projection from the LGN to the visual cortex is called the optic radiation. Because damage at any point along the pathway from the retina to the cortex results in some degree of blindness, this is clearly the pathway through which conscious visual perception takes place in human beings.
Those of the inferior portions of the visual field travel in the parietal lobe and loop very little. The visual cortex is the last part of the optic pathway and processes the information received from the retina. A large portion of it is occupied by the area which corresponds to the macula lutea of the retina.ptic Radiation and Visual Cortex. Axons of the optic radiation transmit the impulses from the LGB to the visual cortex. Information from the superior portion of the visual fields is carried in fibres which sweep around the inferior horns of the lateral ventricles in the temporal lobe (Meyer's loops).
