FNIRS USE CASE 1: SPEECH PERCEPTIONS, LANGUAGE DEVELOPMENT

Probe placement and experiment design as in [1]. “Newborns can discriminate speech sequences that follow a regularity, such as the repetition- based ABB rule (e.g. ‘mubaba’, ‘penana’, among others), from otherwise similar random sequences (ABC: ‘mubage’, ‘penaku’, among others).”

Although individual variation can never be excluded, this placement should ensure recording from perisylvian and anterior brain regions.

The dashed white lines separate anterior and posterior ROIs. The red ellipses indicate the channels included in the frontal area of interest. The blue ellipses indicate channels included in the temporal area of interest. The results indicted greater hemodynamic responses to ABB sequences rather than ABC sequences in the bilateral temporal and left frontal areas.
