Summary
Electroencephalography (Author’s name) (Institutional Affiliation) Introduction The neurons found in the brain can affect every aspect of human’s life including dreaming, performing mental thought, memories, and completing motor activities. The electroencephalography is a scalp’s surface recording that is generated by various bio potentials in the brain’s cerebral…

However, the advanced signal processing methods are used in separating different brain wave components. The components are associated with various brain functions and areas (Walter, 2001). The present research is focused on the correlation discovery between the specific brain tasks pattern to mental health, sleep phases, and emotional states. In a medical setting, EEG is mainly used for diagnosing neurological disorders like the patient's consciousness, and epilepsy during the surgical procedures. Additionally, it is shown that signals of EEG are used as inputs to control for the other systems like the computer interface. This is important during spinal cord injury in restoring function. The lab uses the Bio Radion in detecting the electrical activity in the cerebral cortex and apply some basic analysis methods in interpreting the data.

The two channels will be in from the frontal region and the other channels will be from the occipital section. The Clevelab software is included when setting up the movie before starting the experimental set up in the laboratory process. 1. In performing the experiment, the subjects should have short hair. The subjects should have free hair gel scalp. The experiment also requires 7 gold cup electrodes. The electrodes will be positioned at 01 and 02, FP1, and FP2 in measuring the EEG, on every mastoid and FPZ from the ground. The processes of mastoid are the structures that are bony like that can be felt behind the ears. Before the application of electrodes to the subject it is crucial to clean and prepare the sites of electrodes. 2. At this stage, the electrode attachment is carried out. Fill the electrode generously with the given gel to fill the cup (“Electroencephalography and clinical neurophysiology”, 2007). Slide the gold cup electrode with the gel into the pad and then push the hair sideways and place electrode on the subject's head at O1. Repeat the other electrode at the locations. The placement of electrodes at point O1 and O2 is shown below. Retrieved on 29th October 2013: http://www.upstate.edu/cdb/education/grossanat/hnsklattb5.shtml 3. Connect the leads of gold cups and jumpers to transmit inputs 1, 2, 3, 4, and the ground by using the outlined figure as the reference (Cohn, 2009). The head’s left has now been symmetrically to the right side from the top down view. As shown in the diagram below Retrieved on 29th October 2013: http://glneurotech.com/bioradio/bioradio-wireless-physiological-monitor/ Procedure and collection of data The procedure of this experiment involves the calibration, data recording, and analysis of data. The setup entails turning the computer on and plug the BIORADIO equipment followed electrode positioning. The second stage is calibration. The stage ensures that the electrodes are good places and the relaxation of the subject. The data that is calibrated is checked to make sure that they are the same. Consequently, the data recording is performed when ...Download file to see next pagesRead More
