Nucleus reuniens of the midline thalamus of a rat is specifically damaged after early postnatal alcohol exposure.

ABSTRACT: Individuals diagnosed with fetal alcohol spectrum disorders often show behavioral impairments in executive functioning. Mechanistic studies have implicated coordination between the prefrontal cortex and the hippocampus (through thalamic nucleus reuniens) as essential for such executive functions. This study is the first to report the long-term neuroanatomical alterations to the ventral midline thalamus after alcohol exposure on postnatal days 4-9 (a rodent model of binge drinking during the third-trimester of human pregnancy). Alcohol added to a milk formula was administered to female Long-Evans rat pups on postnatal days 4-9 (5.25 g/kg/day of ethanol, intragastric intubation). Control animals were intubated without the administration of liquid. In adulthood, brains were immunohistochemica
