    Humans have been studying eye movements for many years now. The first recorded person to publish studies that contributed to the field of eye tracking was Louis Émile Javal [1, 2] in 1878, roughly a century before computers started becoming commonly used. Javal observed human eye movement while reading and was the first to observe that eyes make a combination of rapid movements (which he called saccades) and short stops (which he called fixations). Javal conducted this experiment without the assistance

    object is identified, smooth pursuit eye movements are used to track the object as we, or the object, move through the environment. Smooth pursuit eye movements are slow eye movements that follow a target and are used to maintain its position on the fovea. The smooth pursuit eye movements studied here are conjugate with the eyes moving together and the angle between them preserved. A visual stimulus is usually required to initiate a smooth pursuit eye movement (Rashbass, 1961). Although, by degrading

    Eye blink and eye movement are the artifact in the recorded EEG signal. The eye which consists of electrical dipole and eye sight change due to the eye movement and eye blink and also which causes change over the scalp. One approach is used for analysis and suppression of artifact is wavelet based technique. The other technique also used which effectively suppress the artifact is data driven technique is called empirical mode decomposition (EMD) with cross correlation. The EEG recorded EEG signal

    stages of sleep, rapid eye movement and Non-rapid eye movement. During rapid eye movement(REM) sleep, your voluntary muscles are paralyzed, your eyes move rapidly under your eyelids, and 90% of your dreams occur. In rapid eye movement sleep, your heart beats faster and body temperatures increase to near waking levels. While conscious, you have a total of 4 different sleep waves determining the 4 different stages you enter during rapid eye movement sleep. In Non- rapid eye movement(Non-REM) you are able

    predominant, societal, white aesthetic and through the perceptions associated with physical characteristics. In The Bluest Eye, Toni Morrison first illustrates the reinforcement of racial hierarchies through the proliferation of a predominant, societal white aesthetic by recounting passages from the Dick and Jane books, a standardization of family life. Next, “The Black Arts Movement” by Larry Neal demonstrates the reinforcement of racial hierarchies through the proliferation of a white aesthetic by

    vertebrates below mammals, all the fibers cross. It must be pointed out that no motion processing is actually done in the optic chiasm. About 20% of the axons leaving the optic chiasm go to the Superior Colliculus, which is responsible for certain eye movements and spatial localization. The remaining 80% of the axons go to the Lateral Geniculate Nucleus, LGN (Schiffman, 2000, p. 71-73). The LGN represents the next motion processing step after the M-cells in the retina. The Magnocellular Division

    Cerebellar Lesions The cerebellum integrates sensory and other inputs to coordinate ongoing movements and participate in motor planning. The cerebellum has no direct connections to the lower motor neurons but modulates motor function through upper motor neurons. The Vermis and flocculonodular lobes regulate balance and eye movements via connections with vestibular nuclei and oculomotor system, these regions control the medial motor systems. The more lateral areas of the cerebellum control

    REM Sleep Behavior Disorder

    Our awareness of the complexity of sleep expanded in 1953 with the discovery of rapid-eye-movement (REM) sleep by Aserinsky and Kleitman. Sleep was no longer considered a homogenous state, but rather a dynamic process of cycling between two distinct states, non-REM and REM sleep. Under normal circumstances the boundaries between non-REM, REM and wakefulness are well declared. Dissociative sleep disorders involve a breakdown of these boundaries (Mahowald and Schenck 1992), and provide a unique window
