No results posted yet for this study

Summary

The objective of this study is to determine the effects of electrical brain stimulation (EBS) on visual search in natural scenes in humans.

Conditions

  • Cognition
  • Attention
  • Eye Movements

Interventions

DEVICE

Electrical Brain Stimulation

Electrical Brain Stimulation (EBS) will be used to disrupt local neural activity in inferior temporal regions (ITC), parahippocampal cortex (PHC), the hippocampus, and control regions. The effects of EBS will be examined on attention and eye movement behavior, and all participants will receive both EBS and sham electrical brain stimulation.

DEVICE

Sham Electrical Brain Stimulation

Sham electrical brain stimulation (SEBS) will be applied to inferior temporal regions (ITC), parahippocampal cortex (PHC), the hippocampus, and control regions. The effects of SEBS will be examined on attention and eye movement behavior, and all participants will receive both SEBS and EBS.
