area is important for determining which objects our eyes shift to when they move. Studies have shown that there is a large amount of activation within the visual area V4 before the saccade even takes place. This occurs in the form of shrinking receptive fields. The receptive fields of these brain cells tend to shift towards the object that the eye is about to move towards, generally more so if the object is close to the original fixation point. This dynamic change in receptive fields is thought to enhance the perception and recognition of objects in a visual scene. Because the receptive fields become smaller around the targeted objects, attention within the visual scene is very focused on these objects. Increased attention to target objects within a visual scene help direct eye movements from one object to another. Understanding of the visual scene becomes more efficient because these attention shifts guide the eyes towards relevant objects as opposed to objects that may not be as important. Lateral intraparietal cortex The lateral intraparietal cortex (LIP) is an area that is believed to be primarily responsible for keeping an image fluid and undistorted during a saccade (visual/spatial constancy). Past work has shown that the LIP stores information of objects before the saccade (presaccadic), which is then followed by a shift in the receptive fields of the brain cells of this area to compensate for the displacement of the retina during a saccade. This shift in the receptive fields occurs nearly 80 ms before the saccade. The LIP uses quantitative spatial information in order to achieve this shift, which allows for the perception of visual and spatial constancy. The receptive fields of the LIP are quite large and therefore are not well suited to hold details about the perceived objects in the scene during a saccade. This is why objects may seem somewhat blurry during eye movements. Posterior parietal cortex The posterior parietal cortex (PPC) is a cortical area that is located in front of the parieto-occipital sulcus and is known to play a role in spatial awareness for eye and arm movements. A study using transcranial magnetic stimulation (TMS) found that the PPC also plays an important role in the amount of information held across saccades. It is believed that transsaccadic memory has the ability to hold roughly three to four items across each saccade with a fully functional PPC. When the
