The Behavioral Research and Imaging Neurodevelopment lab is committed to interdisciplinary neuroscience research involving both undergraduate and graduate students who are interested in exploring the relationship between brain function and human behavior. One of the tools to explore brain function is electroencephalography (EEG).
Electroencephalography is a technique employed to record the spontaneous electrical activity of the brain. These biosignals, which EEG detects, have been demonstrated to represent the postsynaptic potentials of pyramidal neurons in the brain. EEG is non-invasive, involving the placement of electrodes along the scalp, often referred to as "scalp EEG."
The EEG measures voltage fluctuations, enabling the assessment of regular brain activity. EEG signals primarily mirror the activity of cortical neurons located in close proximity to the scalp electrodes. In this lab, we are interested in using EEG to provide insight into the electrophysiological correlates of:
EEG is an invaluable resource for both research exploring brain behavior relationships and in clinical decision making. It stands out as one of the few mobile techniques available, offering temporal resolution in the millisecond range.
NSF Major Research Instrument (MRI): Acquisition of Electroencephalography (EEG) for Examination of Brain-Behavior Relationship across the Life Span. (9/1/2021-8/31/2024) FAIN: 2117233; Direct Cost: $149,919; Total Cost: 221,880, Recipients Drs Lajiness-O’Neill (PI), Bo, Hashimoto, Lawler, Staples.
A team of faculty secured a National Science Foundation (NSF) Major Research Instrumentation (MRI) grant in 2021 and purchased a 128-channel (high-density) electroencephalography (EEG) system. The high-density EEG system is the first neuroimaging tool on EMU campus that allows us to measure human neurophysiology. It is for shared use across three departments/programs: Neuroscience Program (NSCI), Psychology Department (PSY), Communication Sciences and Disorders Program (CSD), and two colleges (College of Arts and Sciences and College of Education).

The EEG equipment is housed in Mark Jefferson Science Complex Room 528 B.R.A.I.N (Behavior Research And Imaging Neurodevelopment) lab. It is now used by at least three research groups within the Departments of Psychology, Communication Sciences and Disorders, and Neuroscience Program at EMU.
Research demonstrates that executive functioning (EF) abilities impact multiple areas of functioning, including internalizing and externalizing difficulties as well as school readiness and academic achievement. Preschool is a time of rapid EF development, making it an ideal time to identify children with EF weaknesses and provide targeted interventions. The current study explores the association between resting state EEG power in frontal and parietal brain regions and EF abilities in preschoolers. We also aim to examine whether the known association between early indicators of regulation and later EF is mediated by resting state EEG power.
Understanding the mechanism by which early predictors lead to EF weaknesses is crucial to develop more targeted screening and intervention efforts. By characterizing resting state EEG power in typically developing children, exploring the associations between EEG power and directly measured EF abilities, and examining the role of EEG power in the association between early regulation and later EF abilities, this study hopes to aid researchers and clinicians in differentiating normal from atypical EF development and more effectively targeting treatment.
