# Brain-OF: Omnifunctional Foundation Model for fMRI, EEG and MEG

> Single unified architecture that can process fMRI, EEG, and MEG data through modality-specific encoders and a shared backbone.

## Metadata
- **Source**: arXiv:2602.23410v2
- **URL**: https://arxiv.org/abs/2602.23410v2
- **Category**: Brain Imaging / Foundation Models

## Core Methodology

### Key Innovation
True omnifunctionality - one model handles three major neuroimaging modalities without separate training per modality.

### Technical Framework
This methodology provides:

1. **Problem Definition**: Single unified architecture that can process fMRI, EEG, and MEG data through modality-specific encoders and a shared backbone.

2. **Approach**:
   - Novel architecture/technique specific to this domain
   - Integration with existing frameworks
   - Optimization for target hardware/application

3. **Evaluation**: Rigorous validation on standard benchmarks

## Implementation Guide

### Prerequisites
- fMRI/EEG/MEG basics
- Transformer architectures
- Multi-modal fusion

### Applications
- Unified neuroimaging analysis
- Cross-modal brain studies
- Clinical multi-modal diagnostics

### Code Pattern
```python
# Conceptual implementation framework
# Adapt based on specific paper details

import torch
import torch.nn as nn

class MethodTemplate(nn.Module):
    def __init__(self):
        super().__init__()
        # Implementation details from paper
        pass
    
    def forward(self, x):
        # Forward pass logic
        pass
```

## Pitfalls
- Requires careful hyperparameter tuning
