Catecholamines, acetylcholine, and vasopressin, are three [among many] of the beneficial hormones and other helpful neuropeptides that are produced in specific brain frequencies. Studies have shown that acetylcholine is vital for long term memory. They have also found that when acetylcholine production [in the brain] is high, we experience boosts in our long-term memory. Individuals who have lower levels of acetylcholine usually struggle with tasks involving learning and memory. At the end of your day listening to Traders Mindset produces the neuropeptide vasopressin – a neuropeptide which improves reaction time, ability to learn, and ability to remember. 
It is not only our production of neuropeptides that allows us to learn more effectively we experience decreased blood pressure, heart rate, and our entire body feels relaxed. This boosts the overall oxygen level in our brains and maximizes blood flow to our cortex. This naturally boosts our attention span and level of alertness. Boosted attention and alertness makes it much easier to memorize and learn new things.
