Experiment Design

The experiment to be used during EEG recording should be properly designed. For example in an event-related EEG experiment, there should be a sufficient number of trials to get the averaged signals after rejection of artifacts. The experiment should follow the ethical guidelines to ensure the participants’ privacy, participants’ consent, duration of experiment, instructions to participants, health-related risks, and the interventions, which induce the hypothesized changes in the brain. In case a participant does not feel comfortable during recording he/she may be disturbed and may engage in irrelevant movements, eye blinks, scratching, yawning, drowsiness, and loss of focus.

Preparation of Participant

The participant should be informed about the schedule of experimentation and the researcher should conduct the experiment to the ease of participants’ availability. If the EEG device to be used in recording requires the participant to shampoo his/her hair, or avoid gel or lotion, then the researcher should ensure the participant’s preparation accordingly prior to the experiment. If there are any other preconditions of the experiment such as proper sleep, avoiding drinks like coffee and alcohol, or physical exercise then the researcher should communicate with the participant to fulfill the preconditions. Prior to the start of the experiment, the participant should be well instructed about the experimental task and procedure of the experiment to avoid irrelevant movements, eye blinks/movements, and scratching during recordings.

EEG System Check-Up

To ensure the EEG equipment calibration, the instructions provided by the original equipment manufacturers (OEMs) should be followed. For the peripherals (such as electrodes/sensors), tuning the operation procedure of the equipment should be strictly followed to avoid calibration errors, and to utilize the sensors’ full capacity of recording voltage potential.
