PHYSIOLOGICAL METHODS

Electroencephalography (EEG)

The core method used within BABA is scalp electroencephalography (EEG), which measures electrical activity at the brain’s surface (i.e. cortex). EEG also involves studying evoked responses, which assess the brain’s reaction to various sensory stimulations. Such combination of study is more formally known as “multimodal recording”. The multimodal studies within BABA are primarily focused on assessing visual and somatosensory systems.

Electroencephalography (EEG) in babies, including its different variations and practical aspects, are shown in this NEMO multimedia package prepared for the NEMO consortium. This NEMO multimedia package is the largest, freely-available educational resource for guiding newborn EEG recordings.

The interactive multimedia package, with its accommodating animations, explains the structural and functional development of early preterm babies.

Eye-Tracking

The tracking of infant gaze, or looking behavior, has rapidly become a popular research method used within the field of developmental psychology. The BABA center was one of the first both clinical- and hospital-based laboratories to begin eye-tracking research in 2010. Infant gaze analysis provides researchers with understanding of an infant’s perception, attention, learning, and memory. The method is based upon an infrared light source and camera. Camera detection occurs as the infant views a stimulus presented on a computer screen. The eye-trackers used within our lab are both remote and automatic–meaning no part of the eye-tracking device comes in contact with the infant. Currently, our lab uses eye-tracking to study both the visual system and cognition of infants between the ages of 3-8 months.
