SUBCORTICAL: Deep brain stimulation and recording
PERIPHERAL: Nerve interfaces (spinal, peripheral nerves)
SPINAL: Spinal cord interfaces for motor/sensory pathways
```

### 2. Signal Types

```
EEG: Electroencephalography (scalp)

## 🧬 Neural Signal Processing

### Signal Acquisition

1. **Electrode Configuration**: Monopolar, bipolar, or Laplacian montage
2. **Sampling Rate**: Nyquist theorem compliance (>2× highest frequency)
3. **Impedance**: < 5kΩ for scalp, < 100kΩ for cortical
4. **Common Mode Rejection**: > 90 dB

### Signal Filtering

```
Low-pass: Remove high-frequency noise (> 500 Hz)
High-pass: Remove DC drift and slow artifacts (< 0.1 Hz)
Notch: Remove line noise (50/60 Hz ± harmonics)
Adaptive: Online artifact rejection and signal cleaning
```

### Feature Extraction

- **Time Domain**: Amplitude, latency, waveform morphology
- **Frequency Domain**: Power spectral density, band power
- **Time-Frequency**: Wavelet transform, Hilbert-Huang
- **Spatial**: Source localization, connectivity analysis

## ⚡ Enhancement Protocols

### Stimulation Parameters

```
Current: 0.5-5.0 mA (safety limits)
Voltage: 0-10 V (charge-balanced)
Frequency: 1-250 Hz (target-dependent)
Pulse Width: 50-500 μs
Charge Density: < 30 μC/cm² (neuroprotection)
```

### Modulation Strategies

1. **Open-loop**: Pre-programmed stimulation patterns
2. **Closed-loop**: Adaptive based on neural feedback
3. **Demand-driven**: Triggered by user intent or neural state
4. **Coordinated reset**: Desynchronization therapy

## 🛡️ Safety Considerations

1. **Charge Balancing**: All stimulation pulses must be charge-balanced
2. **Thermal Management**: Tissue heating < 1°C above baseline
3. **Impedance Monitoring**: Continuous electrode impedance checks
4. **Seizure Prevention**: Anti-epileptic safeguards for cortical stimulation
5. **Infection Control**: Sterilization and biocompatibility per WIA-AUG-013
6. **Long-term Stability**: Electrode longevity > 5 years (implants)
7. **Reversibility**: Emergency shutdown and removal protocols
