Answer 1

1) How has the study of split-brain patients been informative?

The study of split-brain patients has been informative in helping us learn about how the two hemispheres work together and how important it is for well being. For example, music is perceived differently by them. They associate words with one and music with another. If normal people listen to two songs at once, there is chaos. But for a person with a split brain, they hear one song's lyrics over the other song's tune.

Also, the way they associate visuals with one another is affected. They choose things and provide irrational explanations because they lose narrative. Left hemisphere does not function as correctly as it should due to the severed corpus callosum.

These help us infer that motor control, speech control, visual pairing, and reasoning are important aspects that require both hemispheres to work together.

2) Why is converging evidence the best kind of evidence in the study of brain function?

Because better numbers mean more strength to claims. Brain function is a very tricky area because it is unique. Converging evidence is evidence from multiple sources, studies, observations, experiments, and techniques - all that point to the same outcome or result. This shows that there are very fewer chances of the hypothesis to go wrong and that there is much evidence in proving it right. This is the strongest type of evidence because it shows numbers and proof. That is why it is considered the best kind of evidence in the study of brain function.
