Digital Mind
◎ 前瞻概念How do I perceive, how do I think? = Soul · Disability Assistance
Digital Me answers "what am I made of." Digital Mind answers "how do I perceive, how do I think." Your brain's electrical activity patterns-cortical local field potentials, single-neuron firing sequences, cross-frequency oscillation coupling-are the physical substrate of your cognition. Digital Mind's goal is to build a computable mirror of your neural activity patterns.
Who Are You? Choose Your Entry
Patients & Public
Understand how brain-computer interfaces help people with disabilities. Invasive BCI is limited to medical indications-movement disorders, aphasia, epilepsy. We do not read normal people's thoughts.
Medical Institutions / B2B
Evaluate BCI assistive technology routes and coupling schemes with genomic data. DiVoGenome-DiVoFold5 pipeline can upgrade generic decoding to personalized decoding.
Investors / Peers
Evaluate invasive BCI technology barriers and roadmap feasibility. Synchron Stentrode has FDA breakthrough device designation, ECoG has been routinely used in epilepsy surgery for 20 years.
Understand BCI in 5 Minutes
- 1
Your brain has ~86 billion neurons, communicating via electrical signals
- 2
A Brain-Computer Interface (BCI) reads these electrical signals and translates them into computer commands
- 3
Non-invasive (EEG headset): convenient but signal is fuzzy, like listening through a wall
- 4
Invasive (implanted electrodes): clear signal but requires surgery, like placing a microphone directly in the room
- 5
DiVo only goes invasive-because only invasive can obtain sufficiently precise signals to help people with disabilities
- 6
But invasive is limited to medical indications-movement disorders, aphasia, epilepsy. We do not read normal people's thoughts
Disability Assistance is the Only Realistic Path for Dimension 2
Invasive BCI is currently limited to patients with clear medical indications-this is the legal and ethical baseline. This is not a fantasy of "reading normal people's thoughts," it is medical technology that helps paralyzed patients control robotic arms with thought and helps aphasic people "speak" again. DiVo Gen²AI's DiVoGenome-DiVoFold5-DiVoCell-DiVoSignal pipeline can upgrade these devices from "generic decoding" to "personalized decoding."
Disability Assistance Applications
| Application | Four-Layer Interaction Mapping | Stage | Beneficiaries |
|---|---|---|---|
| Paralysis Patient Motor Intent Decoding | Genetic layer -> developmental layer -> consciousness layer | V1 (2027, ECoG clinical signal) | Paraplegia/quadriplegia patients |
| Aphasic Language Planning Signal Extraction | Developmental layer -> consciousness layer | V2-V3 (2029-2031) | Broca's area damage/ALS patients |
| Epilepsy Seizure Prediction | Genetic layer -> metabolic layer -> consciousness layer | V1 (2027, existing clinical signal) | Frequent epilepsy patients |
| Early Cognitive Decline Warning | Genetic layer -> metabolic layer -> consciousness layer | Long-term (requires long-term data accumulation) | APOE ε4 carriers/Alzheimer's risk population |
Why DiVo Gen²AI Chooses the Invasive Path
Non-invasive (EEG/MEG) is the "not cheap + no precision" trap
| Path | Signal Quality | Daily Experience | Suitable For |
|---|---|---|---|
| EEG | Low (skull attenuation, volume conduction distortion) | Wear headset daily with conductive gel | Curious exploration |
| Endovascular stent electrode | High (mm-level, high SNR) | No operation needed after implant, passive like breathing | DiVo Gen²AI baseline |
| ECoG (cortical surface) | Very high (sub-mm, high bandwidth) | Passive collection after implant | DiVo Gen²AI upgrade |
| Intracortical microelectrode | Extremely high (single-cell resolution) | Passive collection after implant | DiVo Gen²AI long-term |
The core devices of the invasive path were not invented by DiVo Gen²AI-the endovascular stent electrode (Synchron Stentrode) has FDA breakthrough device designation, ECoG has been routinely used in epilepsy surgery for 20 years, and intracortical microelectrodes have already helped dozens of paralyzed patients control robotic arms with thought. What DiVo Gen²AI does: connect these validated high-throughput signal acquisition devices to our own DiVoGenome-DiVoFold5-DiVoCell-DiVoSignal computing pipeline.

Deep Coupling with Digital Me
| Digital Me Layer | Coupling Point | Invasive Signal Advantage |
|---|---|---|
| DiVoGenome (genome) | Neurotransmitter receptor gene variants -> neural activity baseline | Can distinguish firing pattern differences between receptor subtypes |
| DiVoFold5 (protein) | Ion channel/receptor protein variants -> electrophysiological parameters | Can infer functional impact of ion channel variants from firing frequency |
| Gut-brain axis | Microbiome metabolites -> vagal afferent -> cortical activity | Can capture cortical response within hundreds of ms after vagal stimulation |
| DiVoCell/DiVoSignal | Personalized neuron model -> expected firing patterns | Invasive recordings can directly calibrate personalized models |
| Aging trajectory | APOE ε4 × neurodegenerative electrophysiological markers | Gamma oscillation decline is a quantifiable precursor of cognitive decline |
Digital Mind and the Four-in-One
Digital Mind = Soul. The body supports your cognition (Dimension 2 = soul), cognition drives your digital human's behavior (Dimension 3 = shell infused with soul).
- Dimension 1 (Digital Me) genomic data is the coupling foundation for Dimension 2-neurotransmitter receptor gene variants determine your neural activity baseline
- Dimension 3 (Digital VR Me) digital human behavior needs Dimension 2 cognitive patterns as interaction features-infusing soul
- Dimension 4 (Digital Bloodline) cross-generational legacy includes familial transmission patterns of neurocognitive traits as a forward-looking concept
The causal thread is bidirectional: Dimension 2 neural data can reverse-calibrate DiVoCell/DiVoSignal cell models.

| LFP | Local Field Potential-electrical signal of synchronized activity of large neuron populations |
| ECoG | Electrocorticography-electrodes placed on the brain surface |
| EEG | Electroencephalography-electrodes placed on the scalp |
| SNR | Signal-to-Noise Ratio-ratio of signal strength to background noise |
| Synchron Stentrode | Endovascular stent electrode-implanted via blood vessels, no craniotomy needed |
| Volume conduction | Process of brain electrical signals conducting through the skull to the scalp, which blurs the signal |
| Motor intent decoding | Extracting the intention to "move" from brain signals |
| Cross-frequency coupling | Synchronization between different frequency brain waves, may encode cognitive information |
Honest Boundaries
What We Can Do
- High-fidelity motor intent decoding
- Language planning signal extraction and text mapping
- Personalized neuron firing pattern modeling
- Full coupling modeling with all Digital Me layers
- Longitudinal cognitive state tracking and decline warning
What We Cannot Do and Don't Claim To
- Reading specific thought content (qualia)
- Complete consciousness decoding
- Universal mapping from brain signals to arbitrary semantics
Core constraint-invasive implantation is limited to patients with clear medical indications-this is the legal and ethical baseline. V1-V2 only utilizes signals generated in existing clinical workflows. Clinical translation of medical devices must be executed by qualified medical institutions under a complete compliance framework.
