This summer, I had the opportunity to learn how to identify and analyze brain wave activity in different regions of the brain using electroencephalogram (EEG) technology. More specifically, I observed brain activity changes in human participants using the cyclic sigh breathing technique while undergoing physical stress. A cold pressor test, a procedure that involves participant’s placing their arm in a bucket of ice-water of 1 degrees Celsius, was used to induce physical stress. I devised the methodology of the experiment with aid from my mentor, Dr. Onyper. In addition to collecting EEG data, I assisted in collecting respiratory, electrocardiogram (EKG) and electrodermal (EDA) data.
Once data collected was completed, I used Excel, R software and AcqKnowledge to analyze the data, using Power Spectral Density of each brain wave’s corresponding band frequency. I analyzed Frontal Alpha Asymmetry, alpha power from the occipital lobe, global theta and beta power in addition to alpha-theta and beta-theta ratios in different brain regions.
I am grateful to have had this opportunity to deepen my understanding of a field I am interested in, and to have had the chance to use this summer research as a pilot study for my Senior Year Experience research project in the upcoming academic year. I am looking forward to continuing this project!
