Body Works

good for the bod


great for the brain.

I’m thinking about exercise as a daily exhale. The way you study tricky information: repetition over time builds the muscle, and it’s the same with exercise. Ketz et. al 2015 introduced me to the term “oscillatory interactions.” I understand this term: memory is the repetitive, committed process of introduction and retrieval.

“A number of studies have shown a negative correlation between memory retrieval in alpha and beta power, and a positive correlation between retrieval and theta power.”
