What is the dose effect?

The "dose effect" refers to the relationship between the amount of a stimulus or drug and its effect on an organism or system. According to Andrew Huberman, the dose effect is especially significant and can be seen in various studies. The division of data into quartiles, rather than a simple binary categorization, allows a clearer illustration of how different doses influence outcomes, showing a consistent increase or decrease in effects in relation to the dose. This detailed separation into quartiles provides a more nuanced understanding of how incremental changes in the dose can impact the results 1.
