# 🧠 EEG Mental Arithmetic Explorer |
|
|
|
|
|
Interactive visualization tool for exploring the EEG During Mental Arithmetic Tasks dataset. |
|
|
|

|
## Repository Structure |
|
|
|
|
|
``` |
|
|
space/ |

## Dataset |
|
|
|
|
|
This explorer uses the [EEG During Mental Arithmetic Tasks](https://huggingface.co/datasets/BrainSpectralAnalytics/eeg-mental-arithmetic) dataset containing: |
|
|
- 36 subjects with paired recordings |
|
|
- 23 EEG channels (International 10/20 system) |
|
|
- Resting state and mental arithmetic task recordings |
|
|
- Performance-based classification |
|
|
|
|
|
## Usage |
|
|
|
|
|
1. **Select Subject**: Choose from 36 available subjects |
|
|
2. **Choose Recording**: Resting state or mental arithmetic task |
