The constant buzz hum

My brain is never still. Ever. I can’t turn off the constant churning of internal chatter. I wasn’t aware that this was uncommon until fairly recently and it’s only since discovering the default mode network that I can now give it a name.

Dual processing

My wife reads me the most interesting news over coffee most mornings. While she’s doing this I am most often playing Wordle, completing a Sudoku or working my way through 2048. She has commented before that this looks like incredibly hard work: how can I do both these things at once?

Random connections

Spending more time than most in rumination mode makes you better than most at seeing patterns and making interesting connections between things. I often feel my brain works at its best when I go on a long run or fast bike ride and let the default mode kick in. Knotty problems at work or in my personal life unravel as the miles go by.

What does the science say?

My initial research indicates that dysfunction in the default mode network may be central to the definition of ADHD:

What about you?

I’ve connected with a wide range of neurodiverse people on Medium and would love to know what you think. How does this daydreaming, ruminating, never ceasing processing mode affect you? How do you experience it? Are there any other articles you would recommend?
