From: Sex differences in sucrose reinforcement in Long-Evans rats
Sucrose FR training and testing females vs. males. Top: females responded more for sucrose than males and responding for both females and males increased over days of training. Bottom: across the low range of concentrations, females responded more than males and male and females responded more for 3.75 and 7.5% concentrations of sucrose compared to 0% (#vs. 0% concentration, p < 0.05). Across the high range of concentrations, males and females differed at 7.5% (*p < 0.05) and only females decreased responding at the 15 and 30% concentrations vs. 7.5% (#vs. 7.5%, p < 0.05)
