Not Accessible

Your library or personal account may give you access

Abstract

We used emotional speech to elicit brain activity in two-month-old infants and recorded emotion-modulated total hemoglobin changes on the frontotemporal cortex using diffuse optical imaging with a multi-distance source-detector array.
