Summary

This summary is machine-generated.

Modulating the posterior parietal cortex (PPC) with transcranial direct current stimulation (tDCS) causally impacts visual localization. This brain stimulation technique can induce temporary visual misperceptions, highlighting the PPC's role in spatial awareness.

Area of Science:

Neuroscience
Cognitive Science
Visual Perception

Background:

Visual localization relies on integrating bottom-up and top-down processing.
The posterior parietal cortex (PPC) is hypothesized to be crucial for this integration.

Purpose of the Study:

To investigate the causal role of the PPC in visual localization.
To determine if modulating PPC activity with dual transcranial direct current stimulation (tDCS) can induce visual mislocalization.

Main Methods:

Dual tDCS was applied to the left and right PPC, varying electrode polarity.
Participants' visual localization accuracy was measured during and after stimulation.

Main Results:

PPC modulation via tDCS significantly altered visual localization.
Cathodal stimulation over the right PPC induced rightward visual mislocalization.
Effects emerged rapidly, dissipated during stimulation, and reappeared post-stimulation.

Conclusions:

These findings provide causal evidence for the PPC's involvement in visual localization.
Hemispheric interactions within the PPC influence spatial perception, with each hemisphere biasing contralateral processing.
