neurons and glia (and my father’s brain)

Are you in the neuron? Or is the neuron in you?


Steeped in the study of the human brain, I am in preparation for an artist residency at the Tempe Center for the Arts. Consequently I know my brain changes as I learn, while I draw, and even now as I write. I mean it is really changing.

And I guess I can say now my father’s brain is changing too. Dad’s been diagnosed with Alzheimer’s. For awhile I understand (more or less) he has dementia – I now know (more or less) he has Alzheimer’s. And because my father has Alzheimer’s (the most common form of dementia) I decide to focus this summer’s residency on both the healthy brain and the  brain with dementia.

Where to begin….
The residency calls for me to work at the Tempe Center for the Arts (I am 1 of 3 artists that will be in residence this summer).  I can’t help but consider the public. Actually I am always aware of the public, but more in the form of viewer (of the completed work) and not necessarily as part of the process. I will engage with visitors in a thoughtful manner.

While I’ve drawn many studies of the brain in the last few years, now I feel the need for a brain basics course (101). I consider the primary building blocks of the human brain – neurons and glia (neuralgia).  I spend days looking at imagery including the drawings of Santiago Ramon y Cajal (The Beautiful Brain).

I draw and paint a neuron↓.

Neuron Study

I draw glia ↓.  I didn’t know there’s a variety of glial cells!

These particular cells are key in maintaining homeostasis. I think of them as a sort of maintenance crew (though they’re more than that). While I’ve found different ratios, overall it seems glia outnumber neurons 10 to 1 (I’ve also read 6 to 1, 3.75 to 1).

I enjoy detailing the small preliminary study ↓ (not finished yet).
Note: At this point I better understand where abnormal plaques and tangles, as seen in Alzheimer’s, form.

This week my mother sends my father’s brain scans to me. The day the disc arrives, I pop it into my computer. I recognize my dad’s head and  profile. I manage to bring in (and change) the color of the basic black and white scans. I see them light up and they’re beautiful. There are 4 images, 1 rotates while 3 are static. I figure out how to move through layers of the brain. What am I looking at?  I sober up.

I recognize general areas of the brain though I don’t know how to read the particulars of the images. I hope to find someone who can help me make sense of things.


We’ll be installing in a couple of weeks…

The Gallery at TCA presents
draw: the art of curiosity and innovation
May 25-Sept 1
This interactive exhibition celebrates a wide variety of creative media, styles and techniques that incorporate drawing. The “draw” experience includes fine art displays by local artists, exploration stations for doodling and art making, live artist demonstrations and multiple workshop opportunities for all ages.

Meet Artists-in-Residence through Aug. 3

Last month I had the privilege of spending an afternoon with Dr. Jay Braun, ASU Emeritus Professor of Psychology. We talked about the healthy brain and the Alzheimer’s brain. Exercise, he says, is the most important thing one can do to maintain a healthy brain.

I’m off for a run now…
