Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Current neuroscientific and philosophical models of split-brain patients indicate that conscious perception occurs in both hemispheres rather than being exclusively maintained by just one.

The analysis

The claim states that one hemisphere exclusively maintains continuous consciousness in split-brain patients. The retrieved papers discuss how split-brain subjects can consciously perceive and identify stimuli presented in opposite hemifields, demonstrating bilateral conscious processing rather than exclusive single-hemisphere consciousness. Therefore, the claim is refuted.

Paper [1] indicates that split-brain subjects possess conscious experiences on both left and right sides, pointing to models that account for dual perceptual processing rather than single-hemisphere exclusivity.
