They talk about how complex movement in creatures typically correlates with the size of the brain. Anecdotally, I’ve been doing the Cambridge Brain Sciences[1] tests every so often over the past few months to see how various things affect my score (mainly because I wanted to see which nootropics were most effective) and the best scores always occurred on days where I got exercise and the worst scores were in days where I didn’t and also got little sleep. My absolute best scores (99.5 percentile, although the next days scores were much, much lower and my average has been about 50-60ish) were on a day when I got approx 1.5 hours of brisk walking (throughout the day, not all at once), 8+ hours sleep the night before and I had been taking nootropics. I imagine diet also plays a part, but I’ve not yet experimented. I’m also not sure f sleep or exercise affects me most positive, but together they certainly make a huge difference. Nothing conclusive, for sure, but it does make me think that exercise/movement may play a big part. [1] https://cambridgebrainsciences.com https://cambridgebrainsciences.com
