Case Study
Researchers performed optogenetic fMRI to clarify the whole-brain effects of serotonergic projections, combining optogenetic stimulation of DRN serotonergic neurons and whole-brain activity mapping. They used transgenic mice expressing light-activated cation channels under the Tph2 promoter alongside wild-type controls implanted with optical cannulae, and recorded whole-brain BOLD signals with an 11.7T MRI scanner. Post-testing verified the effectiveness of optogenetic stimulation. The results demonstrate that light-gated microbial opsin--based actuators allow stable, specific modulation of serotonergic circuits and reliable whole-brain imaging.

FAQs
Q: How do I choose between AAV and Lentivirus for my optogenetic experiment?
A: Choice depends on your target tissue and required duration. AAV is generally preferred for in vivo CNS applications due to its low immunogenicity and long-term expression, while Lentivirus is excellent for larger genetic payloads. Our team can provide a comparative analysis based on your specific model.
Q: Can you prepare actuators that respond to red light for deeper tissue penetration?
A: Yes, we offer several red-shifted opsins (e.g., ReaChR) which allow for deeper penetration and reduced phototoxicity. These are ideal for multi-color experiments where you need to activate two different cell populations independently.
Q: Is it possible to target only the axons of a specific projection?
A: Yes. We can incorporate specific targeting sequences, such as those derived from mucin motifs or GAP-43, to ensure the actuator is preferentially trafficked to the axonal compartment, enabling precise projection-specific modulation.
Q: What measures do you take to ensure the viral vectors are non-toxic to neurons?
A: We perform rigorous endotoxin testing and utilize high-purity purification methods (e.g., iodixanol gradient centrifugation) to remove empty capsids and contaminants that typically cause neuroinflammation.
Q: Are your actuators compatible with wireless, battery-free stimulation systems?
A: Yes, our preparation service is designed to be fully compatible with the latest NFC and inductive-powered wireless platforms. We ensure the light sensitivity of the actuators matches the output parameters of modern micro-LED systems.
