  1. 1. Evaluation of the infrared reflection method for saccadic eye movement velocity analysis

    Författare :Frank Träisk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Infrared reflection; Scleral search coil; Saccade; Main sequence; Eye-tracking.;

    Sammanfattning : Saccades are rapid eye movements that change the orientation of the eyes onto objects of interest. In an every day situation saccadic eye movements are used for e.g. reading, scanning objects and enviromnents. LÄS MER

  3. 2. Volterra Modeling and Estimation of the Human Smooth Pursuit

    Författare :Viktor Bro; Alexander Medvedev; Geoff Chase; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volterra models; Volterra-Laguerre models; Nonlinear modeling; Smooth pursuit; Eye tracking; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This thesis treats the mathematical modeling of the human smooth pursuit system using Volterra-Laguerre models. The smooth pursuit system allows for tracking of moving objects. Since it is a complex system including the muscles of the eye, nerves and certain parts of the brain, the system may be impaired if some part is compromised. LÄS MER

  4. 3. Effects of eye and neck muscle proprioception on ocular motor control in normal and strabismic subjects

    Författare :Ying Han; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :strabismus; binocular function; proprioception; eye position; muscle vibration; eye muscle; neck muscle; hand pointing; accommodative vergence movement; dynamics;

    Sammanfattning : Abundant proprioceptive information originates in eye and neck muscles but their role in normal visual function is unknown. Under experimental conditions, proprioceptive activation induces illusory visual movement, whereas clinical evidence indicates that proprioceptive dysfunction causes disturbances in spatial orientation.

  5. 4. Effects of acute alcohol intoxication on human sensory orientation and postural control

    Författare :Fredrik Modig; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Alcohol affects balance and is related to falls and injuries. Even though alcohol effects on balance and eye movement have been studied before we know less about the dose and time dependent effects and how each supportive sense to balance contributes during acute alcohol intoxication.

  7. 5. Sequelae after Facial Palsy : Clinical, Anatomical and Electrophysiological Studies

    Författare :David Jensson; Andres Rodriguez-Lorenzo; Lars Jonsson; Göran Laurell; Sinikka Suominen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Facial palsy; Marginal mandibular paralysis; Smile reconstruction; Synkinesis; Surgery; Kirurgi;

    Sammanfattning : Background: Sequelae after peripheral facial palsy, which among others include synkinesis, non-functional smile and/or lower lip asymmetry, may be devastating for the patient. Bell’s palsy is the most common form of peripheral facial palsy. LÄS MER
