The Neuro-Developmental ERP Lab studies the relation between the brain and behavior during development. We focus on the development of a number of skills, mainly on the executive aspects of attention and control (e.g., inhibitory control, monitoring, and error detection), and how temperamental and environmental characteristics interact and affect the development of the child’s self-regulation. We focus on normative development and also on neuro-developmental syndromes such as ADHD, FASD, etc.
Research Method
We record the electrical activity of the brain as it is reflected on the surface of the scalp. We are basically performing a derivative of electroencephalography (EEG). Because we are just recording, this method is non-invasive and absolutely safe. It has the approval of the Ministry of Health in the USA, Europe, and Israel. Moreover, we have received official Helsinki Committee approval for our studies.
The EEG is recorded using a Geodesic Sensor Net. This net is made with 128 electrodes that are woven together to form a cap for the head. We attach the net using a saline solution (salt water) warmed to body temperature. The electrodes are embedded in soft sponges that are in contact with the hair and scalp, without the need to use any type of gel. The net is placed on the head as easily as a bathing cap. There are nets to suit different head sizes.
Before an experiment, our participants (or parents, in the case of an infant) receive a full explanation of the procedure and give their written consent to participate in the experiment.
During a study, the participant observes stimuli. These stimuli are called events. The analysis of the electrical brain activity is performed afterwards, in relation to the events that occurred during the experiment; therefore, this analysis is known as an event-related potential (ERP).
