Working memory follows an upside down U shaped function with respect to dopamine levels in the prefrontal cortex.
If dopamine levels are too low or too high, working memory suffers.
Protocols for Increasing Dopamine and Working Memory
😴 Non Sleep Deep Rest (NSDR)
i.e. a 20-30 minute nap
🥶 Cold exposure
e.g. 30s - 3m cold shower
cold enough to be uncomfortable
Increases catecholamines
⚠️ Do not hyperventilate or hold your breath while in cold water.
🎧 Binaural beats during or before tasks
Scientific studies demonstrate improvements in working memory, but not necessarily dopamine
💊 Over the counter supplements
1. L-tyrosine - very high doses produce a small effect; not recommended
2. Mucuna pruriens (L-DOPA) - discuss with your doctor; roughly equivalent to L-DOPA, a prescription drug
