Alterations in social behavior are among the major negative consequences observed in children with Fetal Alcohol Spectrum Disorders (FASDs). Several independent laboratories have demonstrated robust alterations in the social behavior of rodents exposed to alcohol during brain development across a wide range of exposure durations, timing, doses, and ages at the time of behavioral quantification. Prior work from this laboratory has identified reliable alterations in specific forms of social interaction following moderate prenatal alcohol exposure (PAE) in the rat that persist well into adulthood, including increased wrestling and decreased investigation. These behavioral alterations have been useful in identifying neural circuits altered by moderate PAE(1), and may hold importance for progressing toward a more complete understanding of the neural bases of PAE-related alterations in social behavior. This paper describes procedures for performing moderate PAE in which rat dams voluntarily consume ethanol or saccharin (control) throughout gestation, and measurement of social behaviors in adult offspring.
社交行为改变是胎儿酒精谱系障碍(FASDs)患儿所观察到的主要负面后果之一。多个独立实验室已证明,在大脑发育期间接触酒精的啮齿动物,无论行为量化时的接触持续时间、时间点、剂量和年龄如何,其社交行为都会发生显著改变。本实验室之前的研究发现,大鼠在孕期适度接触酒精(PAE)后,特定形式的社交互动会出现可靠的改变,这种改变会持续到成年期,包括扭打增加和探究减少。这些行为改变有助于识别因适度PAE而改变的神经回路(1),对于更全面地理解PAE相关社交行为改变的神经基础可能具有重要意义。本文描述了大鼠在整个妊娠期自愿摄入乙醇或糖精(对照)进行适度PAE的操作程序,以及对成年后代社交行为的测量。
