Implementation Considerations

• Requires expertise in electrophysiology, neural signal processing, and closed-loop system configuration.
• Dependent on instrumentation capable of simultaneous neural recording and stimulation (e.g., implanted devices with real-time processing).
• Necessitates cross-team standardization of spike-sorting criteria and stimulation parameters for reproducible results.
• Involves adaptation considerations when translating rodent neural patterns to human-relevant targets or disease models.
• Practical limitations include signal-to-noise challenges in chronic recordings and the need for careful template selection to avoid false-triggering.
