==Data Overview==
[[Image:SOCR_Data_Dinov_June2008_NI.png|150px|thumbnail|right| Neuroimaging Data ]]
Neuroimaging MRI data from asymptomatic subjects was acquired to develop a structural brain atlas (Shattuck, et al., 2008). The raw data was processed in two different ways to test a '''research hypothesis that super-resolution image enhancement would improve automated volume parcellation'''. Thus, an automated volume parcelation (Tu, et al., 2008) was applied first to the raw data and then to the super-resolved enhanced volumes (Marquina and Osher, 2007). Two measures of quality of the automated volume parsing were used -- [[AP_Statistics_Curriculum_2007_Hypothesis_Basics | sensitivity and specificity]].

Finally the results of the Sensitivity and Specificity measures were compared for the two analysis protocols -- applying the auto-volume parser directly to the native data (Standard method) and preprocesisng the native data with super-resolution enhancement (Super-Resolved) before using hte automated volume parser. Of interest was whether the second protocol (supre-resolved analysis) would produce more reliable, consistent and accurate automated volume tesselations, compared to the first protocol (standard method) where a super-resolution preprocessing was not applied.

-The [http://en.wikipedia.org/wiki/Prefrontal_cortex prefrontal cortex] is the anterior part of the frontal lobes of the brain in front of the premotor areas. Prefrontal cortex includes cytoarchitectonic layer IV and includes three regions: orbitofrontal (OFC), dorsolateral prefrontal cortex (PFC), anterior and ventral cingulate cortex. Human brains are much distinct from the brains of other [http://en.wikipedia.org/wiki/Primate primates] and [http://en.wikipedia.org/wiki/Ape apes] specifically in the prefrontal cortex. These structural differences induce significant functional abilities which may account for the significant associating, planning and strategic thinking in humans, compared to other primates. The study below investigated the quantitative differences between the the PFC volumes across species and tissue types.
