Effort-based decision-making versus spontaneous foraging tasks reveal divergence in antidepressant effects on motivation in mice
Antidepressant drugs are beneficial for many of the symptoms of depression, but impairments in reward and motivation often remain or become worse. The effort-based foraging (EBF) and the effort-for-reward (EfR) tasks target different aspects of reward processing and motivation. This study investigated the effects of different antidepressants on effort-related decision-making (EfR) and motivation to engage with natural foraging (EBF). 2 cohorts of 16 and 24 C57bl/6J male mice were used in fully randomised, counterbalanced within-subject designs for acute pharmacological studies (escitalopram, v
