Oscillations, Week 47, 9:11. I have been exploring contrary motion in my improvising lately – here’s a quick example I came up with during this process. It feels like our brains, as hyper-organizers and planners, can move in contrary motion from our thoughts, and sometimes it’s nice to explore that through a wandering mind, a daydream, a journal with scribbled imaginations, a walk down an unknown path, or a musical phrase that has no start or finish. In some cases these contrary motions can be debilitating, as with epileptic patients. In college I had a friend with epilepsy who tragically passed away due to complications related to a seizure, but he had been talking with a specialist who considered removing one of the affected areas. We had long, memorable conversations about how this might’ve affected his life, but he wasn’t able to see that moment through. I think of him and his noble spirit often.

Another invasive epileptic exploration involves implanting electrodes on various areas of the brain’s surface, which is a helpful way neuroscientists can record brain rhythms more accurately than a standard EEG. For example, a group of researchers at Stanford took a deep look into the retrosplenial cortex, folded inside of the corpus callosum, in epileptic brains. Recording activity in this region is made possible by these electrode implants. When those patients recalled memories about their lives, the authors saw a theta band interaction (3-4Hz) between the retrosplenial cortex and the medial temporal lobe that was unique. The retrosplenial cortex is also known to be suppressed during moments of focused attention and active working memory. I’m wondering now if autobiographical memory and memory for doing things are inherently contrary? I’d love to hear your thoughts about this, write me a message if you have a moment! #Oscillations2021 #SoloSaxophone
