What process is used to record the electrical activity of the brain through the use of electrodes attached to the scalp?
An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp.
Which machine is used to record the activities of brain?
An EEG machine is a device that records the electrical activity of the brain.
What is the process of recording electrical activity of the brain?
Electroencephalography, technique for recording and interpreting the electrical activity of the brain. The nerve cells of the brain generate electrical impulses that fluctuate rhythmically in distinct patterns. The recording produced by such an instrument is called an electroencephalogram, commonly abbreviated EEG.
Why is there electrical activity in the brain?
Electrical activity is used in the brain in order to fire electrical impulses to communicate with each other. Neurons use electrical signaling to receive and send information. When a neuron is stimulated, an action potential is fired, which enables the message signals to travel rapidly down the axon terminal.
How do you study brain activity?
Some techniques that may be used for studying the human brain include:
- Electroencephalogram (EEG)
- Magnetoencephalography (MEG)
- Functional magnetic resonance imaging (fMRI)
- Photon migration tomography.
- Transcranial magnetic stimulation.

What is the best way to determine brain activity levels?
Electroencephalography (EEG) Electroencephalography, or EEG, is probably the second-best known technique for recording neural activity. Whereas fMRI records blood flow, a proxy of neuron activation, EEG directly records the brain’s electrical activity via electrodes placed on the scalp of the subject.
