Explaining and understanding synesthesia is not so easy.
On the one hand do we not yet fully understand the neurological bases of this phenomenon. On the other hand, it is tricky to put synesthetic perceptions into words.
Here a selection of videos that do a good job in explaining synesthesia.
1. The pioneer
The synesthesia pioneer and his beautiful teachings about synesthesia. Find more information about his work here.
2. Solid overview
Solid overview without exaggeration.
3. Genetics and the Brain
DNews. I like how the try to explain what happens in the brain when percieving numbers in colors.
4. Afterthoughts by the father of synesthesia testing
David Eagleman and his thoughts. He had some good examples of how synesthesia can improve memory. Visit his synesthesia research on synesthete.org
Well, I guess this helped to get a nice summary of synesthesia. But whatever the scientific and theoretical background of synesthesia is, the beauty of it unfolds in the experience of mindful synesthetic awareness. So, why not just go and try it out? Here we go to the sensorium.
