dinghowthebrainprocessesinformationandadaptsisessentialfordevelopingeffectivetreatmentsforneurologicaldisorders”可知，理解大脑如何处理信息和适应对于开发有效的神经系统疾病治疗方法至关重要。选项A“improvedathleticperformance”意为“提高运动表现”；选项B“enhancedcognitivehealth”意为“增强认知健康”；选项C“bettertelevisionprogramming”意为“更好的电视节目”；选项D“increasedmemoryloss”意为“增加记忆丧失”。只有选项B与原文意思一致，故选B。9.解析思路：根据最
