# An EEG-based Stereoscopic Research to Reveal the Brain's Response to What Happens Before and After Watching 2D and 3D Movies

## TL;DR

This study investigates how watching 2D and 3D movies affects brain activity by analyzing EEG power spectrum density before and after viewing, revealing differences in neural responses across various brain regions and frequency bands.

## Contribution

It provides new insights into the neural effects of 2D and 3D movies on the human brain using EEG analysis before and after viewing sessions.

## Key findings

- Differences in EEG power spectra between 2D and 3D viewing conditions.
- Alterations in brain activity across delta, theta, alpha, beta, and gamma bands.
- Distinct neural responses observed in various brain regions post-viewing.

## Abstract

Despite knowing the reality of three-dimensional (3D) technology in the form of eye fatigue, this technology continues to be retained by people (especially the young community). To check what happens before and after watching a 2D and 3D movie and how this condition influences the human brain's power spectrum density (PSD), a five-member test group was arranged. In this study, electroencephalogram (EEG) was used as a neuroimaging method. EEG recordings of five individuals were taken both before and after watching 2D and 3D movies. After 2D/3D EEG recording, this record was divided into three stages for analysis. These stages consisted of Relax, Watching, and Rest. This benchmarking analysis included I) before and after watching the 2D movie (R2b and R2a), II) before and after watching the 3D movie (R3b and R3a), and III) after watching the 2D/3D movie (R2a and R3a). In the Relax and Rest stages, the 2D/3D EEG power differences in all channels of brain regions for the five EEG bands, including delta ({\delta}), theta ({\theta}), alpha ({\alpha}), beta (\b{eta}), and gamma ({\gamma}), were analyzed and compared.
