I knew about the split brain experiment but never saw it in action like yesterday night.they made a man in the Gallingza et al experiments look at a hammer and a axe thru different eyes corresponding to each hemisphere,and the results were indeed shocking to ym idea of a unified spirit or soul that is just like a radio frequency in the brain's radio as these woo con artists would like you to believe,if you asked one side what did he see he would say hammer,ask the other to write id down and it was a axe,ask again and it was no axe,just a hammer.
to give a summary,here's a post from reddit on the religion sub refuting woo woo glazers of christian apologists 'proving'a soul:
split-brain research doesn't support the existence of a soul. In fact, it does the opposite — it further localizes consciousness to the brain and demonstrates just how mechanically fragile our sense of unified self really is.
When the corpus callosum is severed, the two hemispheres can no longer communicate directly. That’s not speculation — it’s observable in real time. This demonstrates that consciousness — as we experience it — is an emergent property of networked brain functions. Sever the network, and you get dissociation. Not two full-blown minds in a horror movie sense, but functional splits in perception, intention, and control.
"But they still report having one unified conscious experience!"
Yes... but here's the catch: the hemisphere that controls speech is the one reporting. That doesn't mean there's only one subjective experience happening — it means only one part of the brain can verbalize anything. The other hemisphere may be fully experiencing something else — it just has no way to say it.
If anything, this suggests the opposite of a metaphysical “soul.” There’s no evidence of a single, immaterial self holding the system together when the connections are cut. What we get instead is a patchwork of modules that, when working together, create the illusion of a seamless "I."
