The purpose of this study is to use a new technology, functional near-infrared spectroscopy (fNIRS) to study the emergence of cortical involvement in the control of functional motor tasks. Specifically, we are interested in the development of reaching and stepping. We use fNIRS to examine the differences in amount and symmetry of activation of the primary motor cortex (M1) and frontal areas during the execution of these motor tasks.
To enable us to understand the emergence reaching and stepping we will investigate if the amount and symmetry of activation of the arm regions for reaching, and leg regions for stepping will change between the ages of 6 months (low but functional skill level) and 12 months (highly skilled). As this technology is new, we begin by verifying with adults that we are able to 1) map the specific locations of upper and lower limb activity and 2) observe difference between one and two limbs moving in M1. In collaboration with the Pediatric Multimodal Imaging group at the Center for Human Growth and Development (CHGD) at the University of Michigan, we are using a 32-Channel TechEn CW6 system.
