Architectural Layers & Regulatory Standards

• Intracortical Silicon / Polymer Probes (Neuropixels Architecture / Flexible Polyimide Shanks): Recording extracellular single-unit action potentials from pyramidal neurons across cortical layers I-VI.
• Ultra-Low Power Neural Signal Digitization (Analog Front-End ASIC / 30 kHz Per Channel Sampling): Digitizing hundreds of raw electrical channels directly at the skull interface without thermal tissue heating.
• On-Edge Neural Spike Detection & Sorting (Threshold Crossing / Waveform Feature Clustering): Isolating individual neuronal action potentials from background multi-unit hash in real time.
• High-Bandwidth Intent Decoding & Synthesis (Temporal Convolutional Networks / RNN Language Models): Decoding cortical motor intent into continuous 2D/3D cursor kinematics or acoustic phoneme sequences.
