I interviewed Betsy Folwell for a story in Bark Magazine five years ago, and we’ve kept up with each other via email ever since. We have a lot to talk about, I guess: Both of us lost our sight as adults, and both of us are published authors. I was delighted when Betsy agreed to write a guest post for my Safe & Sound blog today, and once you read this entry, I think you’ll see, ahem, why.
Into the Eye’s Mind
by Elizabeth Folwell
Morning announces itself to me not with roosters crowing but squiggles of yellow, blue, white and red on a black background. Like a drawing by Keith Haring. Or an aboriginal sand painting.
Ever since I lost my sight 10 years ago these moving pictures have been part of my routine. In fact, if I wake up without the show I feel cheated.
There’s a scientific name for this phenomenon, of course, and a scholarly explanation. Swiss naturalist and philosopher Charles Bonnet commented on the intense hallucinations his 87-year-old grandfather witnessed. The old man, blind from cataracts, told Charles about the faces, buildings and activities that appeared before him, as real as anything he had seen with young eyes. Bonnet was formulating complex theories about how the nervous system works as a series of vibrations, and the happy village scenes of his grandfather were evidence of energetic pathways between the optic nerve and brain.
We can thank Bonnet, who trained as an attorney but never practiced law, for several modern scientific observations: how butterflies breathe, how primitive animals regenerate limbs, how plants communicate. The last item continues to dazzle researchers today. Bonnet passionately pursued botany and biology until his own failing sight turned his mind inward, to philosophical explanations of nature’s progression toward perfection. To Bonnet, everything was evolving, climbing higher and higher, until insects attained angelhood.
Only some of Bonnet’s work has been translated into English, and he’s remembered more as a religious thinker than scientific innovator. In our times his name is attached to Bonnet syndrome, a handy phrase that family practice doctors and ophthalmologists can tell their patients who ask querulously, “Am I going crazy?” when they describe seeing little green men bouncing purple basketballs down Main Street. I am not making this up; when I described my own psychedelic worm farm to my family doc, he shared that story — without violating any HIPPA rules since he did not say who had aliens on the brain.
When Beth’s blog Imagine described how different parts of the brain respond to words(how, for example, the word “lavender” can make the scent-sensitive territory light up as if a bundle of flowers were right there) I thought of my own suggestible head. The visual cortex, even without accurate input, wants to stay in touch.

Thanks for this post. When Beth said in that other post that descriptions of visual images DO stimulate the brain, I wondered — did she mean you recall light? Images? Or experience something like it. I tried shutting my eyes and recalling a burst of color and I think I can imagine it, though not actually ‘see’ it…Is that what it’s like?
Actually, it’s very much like seeing something for me. The hallucinations are moving, and they have their own life. Not like squeezing your eyes and getting that feeling.
Elizabeth,
Thank you for your description of the “moving pictures”. Is that like when you’d squeeze your eyes really tight as a kid and see colors? I used to love to do that and see all the spots, streaks, and swirls of color.
I loved the information about Bonnet. I’d be interested in learning more about Bonnet’s work in biology and botany. It sounds fascinating! How does one figure out those things about animals? The human mind is incredible!

Charles Bonnet is well known in Switzerland and France, but a stranger to many American science historians, maybe because he lived in the 18th century and few of his ideas went beyond the academy of science in Switzerland. His work would make a fascinating biography, provided the author can read ancient French!
Elizabeth,
Several years ago, a colleague of my husband’s became totally deaf. The onset was sudden and permanent. Our friend, a 60 year old physician, told us that his “brain was making him listen to elevator music with the volume cranked up.” His doctors couldn’t explain it and they made him (one of their own!) “feel crazy.” After surgery for cochlear implants, the music vanished. If Bonnet Syndrome can occur in other regions besides the visual cortex, the mystery music disorder has a name. I’m forwarding your intriguing essay to our buddy. Thanks for solving the puzzle!
It’s been compared to phantom limb, how someone who has had a leg amputated can feel what was once there itch or tingle. Nerves want to stay connected, sending informatiomn to the brain. I bet there is a name for the audio side of Bonnet syndrome, would love to know if you find it.
Betsy,
After reading your guest blog about Bonnet Syndrome, I did some research. The same process that causes Bonnet Syndrome in people losing their sight, does occur in people who are deafened as adults. My friend experienced something called musical hallucinations. Very little
research has been done on it. I was able to find some published scientific studies (done in New Zealand) as well as several single case studies. The NZ docs think that the occurrence of musical hallucinations is vastly underreported. People don’t want to sound (smiling) crazy. Basically the brain “misses” being stimulated by auditory input so it creates something to listen to, mostly music. I put a link to a NY Time article about the process below.
Thanks for writing about Bonnet Syndrome. You gave my brain something stimulating to think about! Kim

Loved this! Thank you.
Beth, do you wake up to squiggles like that, too?
You know what? When I first lost my sight I used to see bright red blobs and, I guess you could call them red “squiggles.” I figured they were the results of the many surgeries I’d had, remaining blood spots in my eyes. After reading Betsy’s post, though, I wonder if I had a case of Bonnet’s Syndrome. The red spots and squiggles are gone now –they only lasted about a year.
