The brain training score is called Thinkie points. Thinkie points represent the degree of activation of the brain (dorsolateral prefrontal cortex). Thinkie points allow us to visualize whether the activity we are currently engaged in is effective in activating our brain.
When our brain is activated, blood flow to the brain increases to deliver more oxygen and glucose for fuel. The Thinkie system measures the increase in brain blood flow using the Thinkie sensor, calculates it using a proprietary algorithm, and displays it as Thinkie points.
