The study of the brain as a five-dimensional organ, with neural connections not just across space and time but across probability branches. This field investigates how neurons in one branch influence their counterparts in adjacent branches, how memories are stored across the probability manifold, and why brain damage in this branch sometimes correlates with enhanced function in another (the universe's cruelest compensation). Spacetime-probability neuroscience has discovered that the brain is not a single structure but a probability distribution of structures, and what we call "consciousness" is just the branch we happen to be observing. This explains phantom limb pain (the branch where the limb still exists is leaking into this one) and why some people can "feel" when someone is staring at them (probability-branch entanglement between observer and observed).
Spacetime-Probability Neuroscience Example: "He had a stroke that affected his ability to recognize faces. His spacetime-probability neurologist explained that in most probability branches, his face-recognition software was fine; he was just stuck in the branch where it wasn't. 'Somewhere,' the doctor said, 'you're recognizing faces perfectly, probably even enjoying it.' He found this cold comfort while failing to recognize his own sister."
