Abstract:

Talk 1: Frontal control of attention and intention studied with dEEG The poles of the frontal lobes have enlarged in recent human evolution, apparently coincident with the expansion of intelligence and skill in self-regulation in social interactions. The mediodorsal regions of the frontal lobe, connected closely with the cingulate gyrus and hippocampus, are important to intentional control of behavior, such as in motivated actions and self-monitoring of those actions. The ventrolateral regions of the frontal lobe, connected to piriform cortex, orbital frontal lobe, the amygdala, insula, and other ventral limbic networks, are important to attentional control of behavior, integrating sensory input to provide feedback guidance of action.

I will illustrate how Electrical Source Imaging (ESI) with dense array (128 and 256 channel) EEG (dEEG) can show the dynamic activity of these frontolimbic networks in self-regulation and self-monitoring during cognitive processing.

Talk 2: Advances in Measuring Children’s Brain Activity A scientific understanding of human behavior can be based in insights into the developmental process, through which the brain grows through multiple stages of embryonic formation, infant attachment and individuation in the nterpersonal context, and self-organization during the child, adolescent, and adult stages of ontogenesis. The dense array (128 and 256 channel) electoencephalogram (dEEG) can provide important information on the neurodevelopmental process, particularly when the specific physical properties of the infant and child head tissues are included in the process of Electrical Source Imaging (ESI).

I will review the changes in skull conductivity in infancy, through childhood, and indeed throughout adult life. One implication of this evidence is not widely appreciated: more electrodes are needed to characterize the information of the infant’s EEG than for the adult’s EEG.
