Electroencephalograph is an electrophysiological monitoring tool that records neuron discharge，The pattern obtained by amplifying brain waves is an electroencephalogram Bet365 games(EEG)，The electrical activity in the EEG associated with specific events is called event-related potential (ERP)。The EEG instrument in the Speech Laboratory of Shandong University is the 64-lead GES 400 produced by Magstim EGI。

1. Hardware system

Net Amps 400 type DC amplifier、64-lead mesh electrode cap、Electrode cap wearing tool、Visual and auditory stimulation workstation、Collection and Analysis Workstation

2. Instrument connection

3. Signal collection

Correction delay;

Wear an electrode cap;

bet365 online betting appDetect gain and impedance;

Collect data

Note: EEG amplitude is very weak，The ideal experimental environment is a shielded room with electromagnetic sound and other shielding functions。

4. Data analysis

Filtering;

Segmentation;

Artifact detection;

Reset reference;

Baseline correction;

Stacked average

5. Common ERP

MMN: Negative wave appearing between about 100~250 ms，Related to processing in the pre-Bet365 gamesspeech attention stage；

P300: Positive wave appearing about 300 ms，Related to the processing of the Bet365 gamesspeech attention stage；

N400: Negative wave appearing about 400 ms，Related to semantic integration processing；

P600: Positive wave appearing about 600 ms，Related to syntactic processing。

6. Application fields
