Universal Brain from Raw Metal Exists? Fact Check
“What component can act as a universal brain that can use raw metal as the needed component”
Summary
Current scientific literature reports the presence and role of various metals in the human brain and advances in metal‑based neuroelectronic implants, but there is no identified component that functions as a universal brain capable of using raw metal as its essential material. The claim is unsupported by existing research.

These flexible probes achieved collocated neural recording and optical stimulation in mouse brains. In general, a precise analysis of neural activity requires a high spatial resolution for the electrical recording and optical stimulation; however, the high-density integration of light sources inevitably introduces stimulation artifacts. Yoon et al. demonstrated the mitigation of artifacts using a multi-metal-layer architecture and heavily boron-doped Si substrate.26 Based on materials engineering innovations, optoelectronic probes integrating 256 recording sites and 128 μLEDs on the surface of four 30-μm-thick Si shanks allowed recording and stimulation across a 0.9 × 1.3 mm brain area in behaving mice (Figure 4b).27
