  Purpose
General anesthetic medications have been shown to cause neuronal cell death in the brains of infant rodents. Ethanol and general anesthetics both act on NMDA and GABA receptors,and appear to have similar mechanisms of toxicity in the immature rodent brain. Functional MRI (fMRI) is a technique developed for mapping brain activation and has been utilized to examine how the brains of children with a history of early exposure to ethanol function differently from children without such a history. This study will utilize fMRI to look for specific changes in brain activation patterns in children with a history of early exposure to general anesthesia, as compared to children without such exposure.

Primary Outcome Measures:
  • Use of fMRI as a tool [ Time Frame: one time 10 to 17 yrs. post-anesthesia ]
    To evaluate the use of fMRI as a tool to investigate the functional consequence of exposure to general anesthetic medications during early brain development


Secondary Outcome Measures:
  • Brain activation patterns [ Time Frame: one time 10 to 17 yrs. post-anesthesia ]
    To compare brain activation patterns in children with and without a history of early exposure to general anesthetic medications while peforming a specific task (go/no-go).
