Title: Impact of Transcranial Random Noise Stimulation (tRNS) on Eye Saccades and Inhibitory Control in Individuals with ADHD

Summary: Attention Deficit Hyperactivity Disorder (ADHD) is the most prevalent mental disorder affecting children, characterized by inattention, impulsivity, and hyperactivity. It is widely recognized as a lifelong condition that can significantly impact various areas of an individual's life, such as academic and career pursuits, social relations, and daily activities, etc. Among the challenges faced by those with ADHD are visual processing deficits, particularly in executing saccades—rapid, precise eye movements essential for shifting visual focus and underpinning visual perception and attention. The cerebellum plays a vital role in regulating the accuracy and control of saccades, as well as functions tied to inhibitory control. A non-invasive brain technique, transcranial Random Noise Stimulation (tRNS) consists of applying random noise using electrodes for modulation of brain activity. In our work, we aim to look at the effect of tRNS on saccades and inhibitory control in individuals with and without ADHD. The participants will perform pro-saccade and antisaccade tasks while being stimulated at the cerebellum with tRNS. We aim to compare the performance outcomes of these tasks between control groups and those diagnosed with ADHD.
