In this practical an electroencephalogram was carried out. An electroencephalogram (EEG) is a test that measures the brain waves and electrical activity of the brain by way of field potentials. It is used in both awake and asleep states. The human brain allows functions of various mechanisms to occur by communication within the brain. The communication within the brain is done through neurons of various sorts‚ sending action potentials through various regions. Each region in the brain will have specific

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

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

ELECTROENCEPHALOGRAPH (EEG) Hans Berger in 1929 was the first person to measure the electroencephalogram measured in humans. Electrical impulses generated by nerve firings in the brain can be measured by electrodes placed on the scalp. The EEG gives a view of neural activity and is used to non-invasively study the physiology of the human brain.EEG activity is a small signal‚ measured in micro volts with the main frequencies of interest up to approximately 30 Hertz (Hz) [1‚2]. The frequency bands in EEG are in table

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

The two-dimensional emotion models and their effect on the brain were evaluated while listening to Indian raga.

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
