Electrical Signal Laboratory - EEG Signal

EEG signals are biological electrical signals generated during brain activity. The billions of neurons in the brain communicate with each other through electrical and chemical signals, and when they discharge, they produce subtle voltage changes. By wearing electrode devices on the scalp, these changes can be recorded to capture the dynamic processes of brain activity. EEG signals reflect the electrophysiological state of the brain, and different frequencies of brainwaves are associated with specific cognitive states and functions.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Electroencephalogram (EEG) signals are the sum of postsynaptic potentials of a group of cortical neurons recorded on the surface of the brain or scalp. It contains a large amount of physiological and pathological information, and is a very typical bioelectric signal. EEG recording is an important tool in the field of neuroscience, providing insights into brain activity and function. EEG plays a crucial role in understanding how the brain works and processes various tasks. Electroencephalogram (EEG) records the electrical activity transmitted from the discharge of brain neurons to the scalp surface, in order to obtain the activation patterns of brain functional areas. It is the overall effect of electrical activity of a large number of brain nerve cells in highly correlated states on the scalp. Electroencephalography (EEG) is a technology that amplifies and records the bioelectric activity of human brain tissue, reflecting the functional status of "live" brain tissue. EEG is recorded by using precision electrical signal acquisition devices worn on the head, and then transmitted through the brain.
