How Analyze was Used
“Manual delineation of the PT utilised Analyze 12.0 (AnalyzeDirect) software with a WACOM Cintiq 13HD graphics tablet, following established delineation instructions from previous MRI non-human primate studies. In each baboon and in each hemisphere, tracing was conducted on coronal planes. The posterior edge of the PT was defined as the most caudal section displaying the Sylvian fissure. The anterior edge was delineated as the most anterior slice with a fully closed insula, coinciding with the Sylvian fissure’s anterior disappearance due to the absence of a landmark defining the Heschl’s gyrus. For each slice, tracing followed the Sylvian fissure’s ventral edge from the medial to the lateral point. Specifically for grey matter results from the newborn baboons10, graders traced to the grey-white matter boundary’s most inferior point. When unclear, the imaginary extension of the Sylvian fissure helped distinguish the grey matter of interest from the dorsal gyrus. This process continued in the coronal plane until the Sylvian fissure vanished.”
