The prenatal alcohol exposure paradigm described here involves voluntary consumption of ethanol (5% v/v) by rat dams during pregnancy. There are a number of protocols for exposing non-human animals to ethanol during brain development represented in the literature, which differ with respect to the timing, dose, duration and route of ethanol administration as well as the species under investigation. Although a thorough treatment of the advantages of various exposure protocols is not provided here, several advantages of the...

An estimated 1-5% of children are diagnosed with Fetal Alcohol Spectrum Disorders (FASDs)2, which include Fetal Alcohol Syndrome (FAS), partial FAS (pFAS), and Alcohol-Related Neurodevelopmental Disorders (ARNDs)3. Deficits in social behavior and cognition are among the most common adverse outcomes observed in children with FASDs4-7. Negative consequences are not limited to heavy prenatal alcohol exposure (PAE), as moderate PAE that does not lead to the conspicuous morphological, behavioral and cognitive deficits characteristic of FAS can cause comparatively subtle, but nonetheless persistent, deficits in humans with FASDs8-10 and non-human animals exposed to ethanol during brain development11. The importance of understanding the behavioral and corresponding neurobiological consequences of moderate PAE is underscored by current estimates indicating that the large majority of FASD cases fall within the less severe range of the spectrum12.
Several independent laboratories have reported alterations in rodent social behavior related to ethanol exposure during brain development, including decreased investigation and interaction1,13-15, altered play14,16,17, increased aggressive interactions17,18, alterations in responsiveness to social stimuli19-21, and deficits in socially acquired food preferences and social recognition memory22. Social behavior deficits have been observed following exposure to heavy (blood ethanol concentrations (BECs) ~300mg/dl)22,23 or more moderate levels of ethanol (BECs ~80mg/dl)1, and across a broad range of parameters for other significant factors including exposure timing, duration of exposure, and age at the time of behavioral measurement.
Previous research has demonstrated that alterations in specific aspects of social interaction in adulthood discriminate rats exposed to moderate levels of alcohol from control animals exposed to saccharin1,18. In particular, moderate PAE has consistently been associated with robust increases in wrestling, which suggests increases in aggressive behavior, and lower levels of social investigation (e.g., sniffing of the partner) in adulthood. Because alterations in social behavior are reliable consequences of PAE, the quantification of social behavior following PAE may hold importance for progressing toward a more complete understanding of the neural bases of PAE-related alterations in social behavior and the development of interventional approaches. The goal of this paper and the associated video is to provide instruction on the moderate PAE protocol and methods for quantification of social behavior in adult offspring that have reliably distinguished prenatal alcohol-exposed from non-exposed rat offspring.

moderate prenatal alcohol exposure and quantification of social behavior in adult rats

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 PAE1, 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.

Over the course of many breeding rounds female rats in the ethanol condition consistently drink an average of about 2.1 g/kg of ethanol per 4 hr drinking session. Rat dams consume approximately one-half of the four hr total during the first 15 to 30 min after the introduction of the drinking tubes, resulting in a peak maternal serum ethanol concentration of about 60 mg/dl, measured at the 45 min time point. Over the remaining 3.5 hr of the drinking period, they continue to consume 5% ethanol at a lower, but relatively st...
