A cost-benefit analysis of demand for food.
TL;DR: This study test the proposition that the fundamental dimension of price is a cost-benefit ratio expressed as the effort expended per unit of food value consumed, and found that grams of food consumed plotted as a function of unit price followed a single demand curve.

Tyrosine Reverses a Cold-Induced Working Memory Deficit in Humans
TL;DR: Administration of tyrosine significantly improved matching accuracy at the longest delay interval most affected by cold exposure, such that matching accuracy in the cold following tyrosines was at the same level as matching accuracy following placebo or tyrosINE administration at 22 degrees C.

Rapid demand curves for behavioral economics
TL;DR: In this article, a method for determining the relationship between food consumption and the price of food (demand function) in behavioral economic experiments is described, which can generate a complete demand function within 7 days, and therefore may be more suitable for use in the evaluation of drugs, toxins and physiological/anatomical interventions.

Tyrosine ameliorates a cold-induced delayed matching-to-sample performance decrement in rats
TL;DR: It appears that supplemental tyrosine was effective in partially ameliorating the effects of cold stress on DMTS performance, possibly by preventing a cold-stress-induced reduction in brain catecholamine levels.

Perceptual bisection in rats: the effects of physostigmine, scopolamine and pirenzepine.
TL;DR: The similar drug effects in different sensory modalities (visual and auditory) and perceptual systems (subjective duration and loudness) suggest that cholinergic drugs may affect perceptual mechanisms responsible for sensory coding, such as the output of a neural generator.
