dc.description.abstractLearning is the act of acquiring new or modifying and re-inforcing existing knowledge, while Memory is relatively the permanent storage of the learned information. Exposure to lead affect brain regions such as hippocampus that are involved in learning and memory. Succimer drug or meso 2,3 – Dimercaptosuccinic acid (DMSA) is a metal chelator which is used as an antidote to lead toxicity. This study aimed at assessing the effect of cowpea (Vigna uinguiculata (L) walp) on learning and memory in acute lead-induced neuro toxicity in mice using Morris water and Barnes mazes. In this study 50 mice (18-22g, aged 6-8 weeks) were used. The animals were divided into two main groups of 25 mice each of the two memory assessment paradigms. Each paradigm has 5 mice allotted to 5 sub-Groups. Distilled water 10 ml/kg, succimmer 20 mg/kg, 250, 500 and 1000 mg/kg Vigna unguiculata aqueous extract were administered orally. Lead acetate solution at 120 mg/kg was also administered orally using canular to induce acute lead toxicity on the first day. The result was not statistically significant in the acquisition sessions and the probe trials for both the Morris water and Barnes mazes when compared to control. At the end of the study, it was concluded that Vigna unguiculata at the doses administered has no effect on learning and memory in acute lead induced neurotoxicity in mice, but that does not mean it lacks total therapeutic benefit. It was recommended that Co-administration of cowpea and succimmer might be of a better therapeutic benefiten_US
