Ventral attention network
The ventral attention network is a unilateral, typically right hemispheric brain network responsible for swapping our focus between various tasks and responding to unexpected cues, making it pivotal to daily function.
Damage to the VAN results in hemispatial neglect, and other forms of cognitive dysfunction.
Connectome analysis of this case in Quicktome revealed that the shortest path from a parietal sulci to the tumor would risk damage to several critical areas of the VAN, including the middle parietal area, important for integrating visual input and motor action, and the parietal Area F part M, which is important for visually guided attention, language processing and decision making.
Quicktome analysis also helped to determine the appropriate sulcus for a trans-sulcal approach with a tubular retractor.
