Abstract<\/p>\n\n\n\n
The article proposes the architecture of an innovative reverse neurointerface \u2014 a neurotransmission device capable of writing semantic information directly into the cerebral cortex.<\/p>\n\n\n\n
The principle of operation is based on the reverse action to electroencephalography (EEG) \u2014 instead of reading brain waves, the device generates controlled patterns of electromagnetic or electrical stimulation corresponding to linguistic units (letter, word, idea).<\/p>\n\n\n\n
To optimize the brain’s neuroplastic response, pharmacological and neurotrophic agents that activate the mechanisms of synaptogenesis and long-term potentiation (LTP) are considered.<\/p>\n\n\n\n
The basic functional architecture of the device is presented and its neurophysiological feasibility is justified.<\/p>\n\n\n\n
1. Introduction<\/p>\n\n\n\n
Neuroplasticity is a key property of the nervous system to change its morphology and functional activity in response to external stimuli, learning, or trauma.<\/p>\n\n\n\n
Modern brain-computer interfaces (BCIs) mainly function in the direction of reading brain activity. However, an effective system for transmitting information to the brain without traditional sensory interpretation, which could activate specific cognitive images or language structures, has not yet been implemented.<\/p>\n\n\n\n
2. Device architecture<\/p>\n\n\n\n
2.1. Basic components:<\/p>\n\n\n\n
– Semantic encoder: Converts words\/ideas into electrophysiological patterns.<\/p>\n\n\n\n
– Stimulation generator: Creates signals of the desired frequency, amplitude, and phase.<\/p>\n\n\n\n
– Matrix delivery system: Transmits the stimulus to specific areas of the brain.<\/p>\n\n\n\n
– Feedback system: Analyzes the brain’s response and adapts the stimulus.<\/p>\n\n\n\n
– Control processor\/AI: Machine learning for individual pattern customization.<\/p>\n\n\n\n
2.2. Principle of operation:<\/p>\n\n\n\n
Words or concepts are encoded as unique neural signals based on previously collected data (EEG\/fMRI). These signals are then generated by hardware and delivered to the brain to reproduce the corresponding neural response.<\/p>\n\n\n\n
3. Pharmacological support for neuroplasticity<\/p>\n\n\n\n
3.1. Pharmacological agents:<\/p>\n\n\n\n
– Nootropics: piracetam, noopept, aniracetam.<\/p>\n\n\n\n
– Antidepressants: escitalopram, agomelatine.<\/p>\n\n\n\n
– Ketamine (in low doses): stimulation of mTOR and rapid antidepressant effect.<\/p>\n\n\n\n
3.2. Natural supplements:<\/p>\n\n\n\n
– Omega-3 fatty acids (DHA).<\/p>\n\n\n\n
– Curcumin.<\/p>\n\n\n\n
– Magnesium L-threonate.<\/p>\n\n\n\n
3.3. Experimental approaches:<\/p>\n\n\n\n
– Microdosed psychedelics: LSD, psilocybin.<\/p>\n\n\n\n
– Optogenetics, DREADD (in animals).<\/p>\n\n\n\n
4. Biosafety and ethical aspects<\/p>\n\n\n\n
Any brain stimulation must undergo clinical testing. Prolonged or uncontrolled activation of neuroplasticity can lead to epileptic discharges, pathological activity patterns, or the formation of \u201cphantom\u201d sensory sensations.<\/p>\n\n\n\n
5. Conclusion<\/p>\n\n\n\n
The presented device model creates a conceptual basis for the formation of a new class of interfaces that do not read but transmit information to the brain using electrophysiologically optimized stimulation in combination with pharmacological support.<\/p>\n\n\n\n
