ELECTROOCULOGRAPHY SEMINAR REPORT PDF

Electrooculography is a technique for measuring the resting and action potential of the retina. The resulting signal is called the electrooculogram. Usually, pairs. Electrooculography, an introduction Electrooculography is the medical terminology for a method used to calculate eye movement, specifically.

When light is switched on, a substantial increase of the resting potential occurs “light peak”which drops off after a few minutes when the retina adapts to the light. The EOG is one of the very few methods of recording semlnar movements that does not require a direct attachment to the eye itself. Please help us clarify the section.

This method is dependent on a terminology called as Resting Potential. We prepared and published this seminar abstract for final year engineering students seminar research.

To measure, the positive and negative points of the retina, Doctors make the use electroculography electrodes. Download your Reports for Electrooculography. There might be a discussion about this on the talk page. Please help improve it or discuss these issues on the talk page. The advantage of EOG eye gaze electrooculograpjy is its simple configuration: In other projects Wikimedia Commons. This difference is due to the large presence of electrically active nerves in the retina compared to the front of the eye.

Assuming that the resting potential is constant, the recorded potential is a measure of the eye’s position. You should do your own research additional to this information before presenting your seminar. Scientists use this method to help disabled individuals control wheelchairs, help them operate computers etc.

It is now accepted that the generated electrical potential arises due to the permanent potential difference 10 to 30mV that exists between the cornea and ocular fundus.

Unlike the electroretinogramthe EOG does not measure response to individual visual stimuli. The important factor regarding the EOG signal is that it does not fall in the amplitude or frequency range eletcrooculography the EMG signal ,thus during reporf process of measurement of the EOG signals ,the head or other parts of the body can be moved ,as these muscular activities will not interfere with the EOG signals and can be filtered easily.

Please help improve this section by adding citations to reliable sources. Because this biological signal is proportional to the rotational angle of eye this technique permits a wide range of rotational angles to be recorded, allows documenting of eye movements when the eyelids are closed and unable the recording in the dark places.

Due to the movement of the retina, there will be a difference in the electrodes. Views Read Edit View history. Many experiments show that the corneal part is a positive pole and the retina part is a negative pole in the eyeball. This technology is based on the principle of recording the polarization potential or corneal-retinal potential CRPwhich is the resting potential between the cornea and the retina.

Please refer to our Seminar PPT preparation guide for a better quality seminar. In the process of detection, the electrodes act as a transducer converting the ion current obtained at the skin to electron current.

Enucleation of the eye. Repprt these positions are constant, a change in the recorded potential originates from a change in elcetrooculography resting potential. The electrooculogram EOG is the electrical signal produced by the potential difference between the retina and the cornea of the eye. In cases of extensive brain damage, where the person is unable to communicate verbally or physically, rsport can use this method to track brain activity.

Resting potential refers to the difference between two smeinar in the retina from its center position. The placement of the electrodes is up and down or right and left.

When the eyes are made to move upwards, then there results an action potential, which when measured will give a value of The amplitude of pulse will be increased with the increment of rolling angle, and the width of the positive negative pulse is proportional to the duration of the eyeball rolling process.

Electrooculography, in addition to other neuromuscular signals, is used as a computer input method by the Neural Impulse Actuator.
