Transcranial direct current stimulation over posterior parietal cortex and temporoparietal junction improves contextual cueing

What is it about?

Contextual cueing refers to a process in which people unconsciously learn spatial patterns that help them locate targets more efficiently, thereby facilitating daily life by reducing conscious effort. This study investigates how two brain regions, the posterior parietal cortex (PPC) and the temporoparietal junction (TPJ), contribute to contextual cueing. Using anodal transcranial direct current stimulation (tDCS), we examined whether stimulating these regions would enhance contextual cueing. Participants performed a visual search task following brain stimulation. The results showed that stimulating both regions improved contextual cueing; however, TPJ stimulation produced a stronger and more dynamic effect, particularly depending on the side of the visual field.
