Synesthesia and Evolution

Dale originally posted the link in another section of the website that isn’t active any more so I wanted to move it into the forum where people could discuss it.

The title is “Synesthesia and Evolution” and here is the post:

Advanced brain scans are enabling researchers to better see the increased connections between sensory brain regions and learn more about the neural condition.

The original content is on National Geographic: Why Does Evolution Allow Some People to Taste Words?

A neural condition that tangles the senses so that people hear colors and taste words could yield important clues to understanding how the brain is organized, according to a new review study.

This sensory merger, called synesthesia, was first scientifically documented in 1812 but was widely misunderstood for much of its history, with many experts thinking the condition was a form of mild insanity.
