科学家们发现了一个在macaques中的脑电路, 它起到“动力刹车”的作用, 当结果涉及不适时防止任务启动。 Scientists have discovered a brain circuit in macaques that acts as a "motivation brake," preventing task initiation when outcomes involve discomfort. 通过抑制腹侧纹状体和腹侧苍白叶之间的交流，研究人员发现猴子更愿意在不适刺激（如呼吸）下开始任务，而不改变风险评估。 By suppressing communication between the ventral striatum and ventral pallidum, researchers found monkeys were more willing to start tasks despite unpleasant stimuli, like a puff of air, without changing their risk assessment. 研究结果表明,这种神经途径可能助长抑郁症和精神分裂症等疾病的动机缺陷,使人们能够深入了解潜在的治疗方法。 The findings suggest this neural pathway may contribute to motivation deficits in disorders like depression and schizophrenia, offering insight into potential treatments. 然而,削弱刹车可能会增加冒险行为,突出表明在人类应用之前需要仔细研究。 However, weakening the brake could increase risk-taking, highlighting the need for careful study before human applications.
