颈动脉内异戊巴比妥程序被用作术前评估语言和记忆半球侧化的标准程序，但尚未应用于研究数字处理。在术前评估计划中连续招募了难治性癫痫患者（n=20）。所有14例左侧语言患者的左脑算术表现更好（颈动脉内异戊巴比妥手术右侧），而6例双侧或右半球语言表征的患者中有5例的右脑表现更好（颈动脉内异戊巴比妥手术左侧）。此外，在左偏侧语言的患者，颈动脉异戊巴比妥程序和算术运算类型之间的相互作用被发现。这项研究表明，语言偏侧化和半球的算术处理专业化之间的密切联系。
The intracarotid amobarbital procedure is used as a standard procedure in presurgical evaluation to assess hemispheric lateralization of language and memory, but has not been applied to investigate numerical processing. Patients with medically intractable epilepsy (n=20) were consecutively recruited during a presurgical evaluation programme. All 14 patients with left-lateralized language showed better arithmetic performance with the left hemisphere (intracarotid amobarbital procedure right), while five out of six patients with bilateral or right-hemispheric language representation showed better performance with the right hemisphere (intracarotid annobarbital procedure left). Furthermore, in patients with left-lateralized language, an interaction between intracarotid amobarbital procedure and type of arithmetic operation was found. The study suggests a close association between language lateralization and hemispheric specialization for arithmetic processing.
