reaction to external stimuli. Frontal asymmetry provides a measure to understand how the brain fundamentally responds to product‚ ads or any other stimuli. The frontal electroencephalogram (EEG) asymmetry is the difference between the left and right alpha activity over the frontal regions of the brain during EEG recordings. The frontal asymmetry can be used to measure emotions and motivations and to also study constructs such as temperament‚ personality‚ psychopathology and cognitive control. (Smith

accident he had while in the military (“Hans Berger Biography”). In the end‚ Berger studied brain waves to test psychic abilities such as telepathy. Berger’s studies lead to a medical breakthrough when he invented the electroencephalogram (EEG) in 1924. The EEG is one of the greatest contributions to medicine‚ and thanks to Berger‚ we have been able to diagnose brain disorders like epilepsy‚ sleep disorders like insomnia‚ find cancerous tumors‚ and even monitor the brain during brain surgery.

measured by using‚ EEG- Electroencephalogram‚ EOG- Electrooculogram‚ and EMG- Electromyogram. In order to measure sleep they use EEG‚ EOG‚ and EMG to categorize the sleep stages. As we sleep we hit four different stages of sleep. The first stage is stage 1 EEG or initial stage 1 EEG which is described as a low-voltage‚ high-frequency signal that is similar to‚ but slower than that of alert wakefulness. During the progression from steps 1‚ 2‚3 and 4 there is a slow increase in EEG voltage and a drop

approximately US$1 million per Tesla and have annual operating costs of $100‚000–$300‚000. Electroencephalography (eeG) EEG uses electrodes applied to the scalp and measures changes in the electrical field in the brain region underneath. EEG has very high temporal resolution (milliseconds) and can therefore detect brief neuronal events. Because the skull disperses the electrical field‚ EEG has low spatial resolution (~1 cm) that depends on how many electrodes are used. The number of electrodes can be

One way of Psychology using technology into their field of work is by the Electroencephalogram (EEG)‚ detects any defects in the brain related to electrical activity.

Music is promoted in all traditions for the well-being of the listener. The objective of this study was to analyze the emotional changes due to Indian music and their effects on the EEG. The two-dimensional emotion models and their effect on the brain were evaluated while listening to Indian raga. Asymmetrical alpha component energy was noticed in the frontal locations with the relative alpha component energy being lower at F3 and F7 positions when compared with F4 and F8 electrode position while

Epilepsy is a group of related disorders characterized by a tendency for recurring seizures. There are different types of epilepsy and seizures. Epilepsy drugs are prescribed to control seizures‚ and rarely surgery is necessary if medications are ineffective. Epilepsy is a disorder of the brain’s electrical system. Abnormal electrical impulses cause brief changes in movement‚ behavior‚ sensation‚ or awareness. There are around 180‚000 new cases of epilepsy each year. About 30% occur in children

Till this date‚ the use of EEG in game research has been sparse‚ perhaps due to the complicated nature of the signal‚ which requires proper signal processing techniques to get correct information content. However‚ EEG is very widely used for assessing workload‚ attention‚ vigilance and other behavioral studies. Findings (Allison and Polich‚ 2008) suggest that cognitive workload

Problem Statement: Seizure prediction in humans through processing of scalp/intracranial EEG recording using machine learning algorithms to aid patients with epilepsy to take precautions to mitigate impact of seizures. Background: Epilepsy is a neurological condition which affects the nervous system. It is also known as seizure disorder. Seizures are caused by disturbances in the electrical activity of the brain [1]. Approximately 50 million people worldwide have epilepsy‚ making it one of the most
