The steps are as the following:1、Preparing the cerebrospinal fluid one hour before the experiment,take some of them for cryopreservation;2、Without paralyse,cuting down the rat head quickly and dislodge the hippocamp part which is used in the experment in freezing liquid,and trim the hippocamp distrct.3、Fixing the hippocamp tissue on the vibratome,to cut down a brain slice with 300μm,use the haustorial tube to move the slice to the preincubate dish,cultivanting it for one hour.Then move it to the record incubation chamfer.4、Preparing the glass micloelectrode and fill it with NaCl,the corcentation is 3mol/L.5、adjusting the recorder,after cultivate the brain slice in the incubation chamfer for 2 hours,the expermentize can be gone on.6、In order to ensure the accurate of the experimental result,use only one medicine concentration for one brain slice in every experiment.

本实验研究方法是：1、实验前1小时配制好所需脑脊液并充以95% O2和5% CO2的混合气，取小部分冷冻保存；2、在乙醚麻醉下，快速断头并在冷冻液里取出包含海马的大脑部位，修整出所需海马区；3、将海马组织固定于振动切片机上切出300μm厚的海马脑片，用广口吸管转移至预孵育皿培养一小时，后再转移到记录用孵育槽内；4、拉制好玻璃微电极，并充以3mol/L的NaCl；5、调试好记录仪器，将脑片在孵育槽内培养2小时后进行实验；6、为了保证实验结果的准确性，每一块脑薄片只进行一个浓度的药品实验。
