It's been known that Increased Corpus Callosum size was found in musicians who began music training before age 7 and that Training working memory leads to growth in Corpus Callosum. As for how to train working memory, that's a diverse subject. There have been a lot of experiments involving Training working memory for ADHD patients, however a meta-analysis ...

First, biological features do not always arise from some intrinsic benefit. They can also be byproducts of other adaptations, or spandrels. That being said, one example of a possible benefit is specialization. For instance, birds will develop asymmetries in their visual system based on light inputs to their outward-facing eye (one eye faces the eggshell, ...

Yes, there are benefits, but I don't think it requires long-term switches. Studies have used this as a manipulation to try and increase self control and have found that it decrease aggression. Based on this, once one has mastered using the non-dominant hand, it seems like the benefit of continuing to use that hand might be over (as it no longer requires ...

I don't know if it's possible to train the corpus callosum, but aside from that, I don't think you can read text in the left visual field for longer than a fraction of a second. To be able to read or see something in your left visual field, your eyes must be focused on something to the right of that (Imagine a fixation cross in the middle of a PC screen ...

The formal name for crossing in biology is decussation. It is thought to be a result of anatomical development as well as a recovery mechanism. Essentially, it's an emergent result of negotiations between genetics, development, and environment. I've emphasized the relevant sentences in two abstracts below. Abstract: The crossing of nerve tracts from ...

I've asked this question about dominance of brain hemispheres. in the question there are examples of drawings made by split brain patients using only one hand and eye at a time. I don't know if using both eyes while drawing produces different results, but the images suggest that the ability to process memory of objects is impaired:

Basically the same as a normal two-halved brain. Circumstances in which function is altered are fairly limited. For details, see case reports on Wikipedia's split-brain page, and this episode of Scientific American Frontiers that features Mike Gazzaniga's research, as mentioned here. Gazzaniga's research was reviewed in a Nature news feature (Wolman, 2012), ...
