[3] The opioid processes involve mu opioid receptors and are present in the rostromedial shell part of the nucleus accumbens [4] on its spiny neurons. [5] This area has been called the "opioid eating site". [6]

Using this method guaranteed the ratios of each observer's judgments and the slope of the sweetness function, S = kC^n (S: sweetness, C: concentration, k: relative ...
