Intra Parietal Sulcus Area 1–2 and Angular Gyrus Differentiates Visual Short-Term Memory and Sustained Attention Activities

Background: Visual short-term memory (VSTM) and attention were found to modulate neural activity predominantly in a superior parietal lobule. This is thought to be the selective attention importance for encoding and manipulation in VSTM. The major area of investigation mainly rested with the differences in the neural substrates and networks mediating these cognitive processes in near and far cortical structures. Summary: Based on previous investigations, the dynamic temporal window route of attention and time locked associated cognitive processes and sub-processes are sketched and its implication in VSTM study is discussed. Imaging cortical structures to isolate closely linked cognitive tasks require circumscribing to certain time-windows in which the paradigm should support to tap time-locked associated processes and sub-processes. Key Messages: The neural activities in intraparietal sulcus area 1–2 and angular gyrus during VSTM encoding are beyond the modulatory effects of selective and sustained attention.
