Developmental Electrophysiology Laboratory

The Developmental Electrophysiology Laboratory is part of the Child Study Center at the Yale School of Medicine. The laboratory serves as a core resource for clinician-scientists at the center who examine typical and atypical development processes of social, emotional and cognitive abilities. Currently the laboratory houses three dense array electroencephalogram (EEG) systems (one portable) for studying brain electrical brain activity (EEG) with “real time” millisecond accuracy. Safe and comfortable, this technology utilizes soft saline-soaked sponges and a small amount of baby shampoo. We easily record the EEG of newborns through adults. With a dense array EEG system we easily apply a net of 128 or 256 electrodes sponges within minutes. The large number of electrodes allows us to apply advanced brain mapping techniques that can be used to localize and visualize brain signals with 2D topographic views and current density maps. The laboratory includes four peripheral physiology systems that help us to understand mind-body interactions in social, emotional and cognitive processes. We rely on the experiment design software Eprime to assess social, emotional, and cognitive processes and to build devopmentally sensitive games for children and adults. Three systems are available in the laboratory—two stationary systems so that subjects may be seen simultaneously—and a portable system to permit EEG data collection in clinics, schools, and other sites outside the standing laboratory.
