What is dense array electroencephalography?
Dense array electroencephalography (EEG) is a technique that uses a large number of electrodes to record electrical activity from the scalp, providing high spatial and temporal resolution.
How does this method improve upon traditional EEG?
This method offers improved spatial resolution and high temporal resolution, allowing for more detailed analysis of brain activity related to social cognition.
What are the key steps in the experimental protocol?
Key steps include preparing the hydro cell sensor net, measuring electrode impedances, taking baseline recordings, and analyzing the data.
Can this method be used with infants?
Yes, the protocol is designed to be applicable for both infants and adults, making it versatile for developmental studies.
What types of questions can this research address?
This research can address questions related to how the brain processes social stimuli and the neural mechanisms underlying social cognition.
What preparations are needed before the participant arrives?
Ensure all equipment is functioning, the experimental room is set up appropriately, and that informed consent is obtained from participants or guardians.
