Electrical Activity

Definition

Electrical activity refers to the patterns of electrical impulses generated by neurons in the brain. These impulses are responsible for transmitting information between different parts of the brain and are crucial for various cognitive and physiological processes.

Electroencephalogram (EEG): A tool used to measure electrical activity in the brain by placing electrodes on the scalp. It provides a visual representation of brain waves.

Event-related potential (ERP): A technique that uses EEG to measure changes in electrical activity in response to specific stimuli or events, providing insight into cognitive processes.

Magnetoencephalography (MEG): Another tool used to measure electrical activity in the brain, but it detects magnetic fields generated by neuronal activity rather than using electrodes.
