Sleeping breaks chains and opens creativity

 

Dreaming allows a daily disconnect from saturating sensory stimulation. The breaking and shrinkage of the dendritic spines in our neurons is a slow task, one that can be nurtured by sleep. Sleep induced forgetting can allow new connections that arise in unexpected ways -- ways unconstrained by memory.

One insight into changes of physiology and its affect on artistic abilities can be seen with the changes in Willem de Kooning's paintings as he contended with Alzheimer's disease. The paintings became less variegated and he embraced simplicity. However, art experts considered his latter paintings to be appropriate parts of his oeuvre. His disease had been migrating from his hippocampi to the upper reaches of his cortical processing. However, his lower cortical hubs, where colors and contours are processed, were thought to be unaffected. He created in a different way.

Claude Monet's "blue period" is a similar artistic response to physiological changes. Perhaps his photoreceptors had less sensitivity to blue light so he over-saturated blue hues to produce the image in his mind. Therefore what we see is not what Monet saw. Is this the case? I don’t know, but I think there is a lot of this occurring in the world of creative expression where art and design have the momentum of the artist and designer pushing them into a higher level of execution than they deserve. At least Marcel Duchamp made fun of this attitude.

Sleeping's effect on dendritic spines is an interesting peek into the physiological encouragements for creativity. Dream on!
