Effect of dietary α-tocopherol supplementation on LTM performance in Effect of dietary α-tocopherol supplementation on LTM performance in senior animals. A . Long-term memory assessment of senior snails before the start of dietary supplementation with α-tocopherol. None of the control (CS-DS) or conditioned (CS-UCS) animals displayed a significant increase in the ΔRasp value indicative of LTM impairment. B. Long-term memory assessment of senior snails following 2 months of α-tocopherol dietary supplementation (+ αTocopherol) or vehicle only (− αTocopherol). Neither α-tocopherol or vehicle treated animals displayed an improvement in LTM performance C. Comparison of spontaneous background rasping rates reveals no significant differences between animals treated with α-tocopherol (+ αToc) or vehicle only (−αToc).
