雏鸡左眼视剥夺不同时程后记忆形成过程与脑内Jun样蛋白表达差异的研究

本实验采用一次性味觉厌恶回避学习，研究２日龄雏鸡左眼视剥夺２４小时后的记忆形成过程，并与左眼视剥夺２小时后的记忆形成过程进行比较，同时利用免疫组化技术，观察并比较单眼视剥夺不同时程及单眼学习后Ｊｕｎ样蛋白在雏鸡脑内不同区域（ＨＶ和ＬＰＯ）的表达。结果表明：１．视剥夺左眼２４小时后对雏鸡的短时记忆、中时记忆和长时记忆均无明显影响，但中时记忆保持水平略低于双眼学习条件下的中时记忆保持水平。这与视剥夺２

THE PROCESS OF CHICK'S MEMORYFORMATION AND EXPRESSION OF JUN-LIKE PROTEIN IN CHICK BRAINS AFTERDIFFERENT TIME OF VISUAL DEPRIVATION

2-day-old chicks were trained to learn the one-trial passive avoidance task after being deprived ofleft-eye vision for 24 hours. Their process of memory formation was compared with that of chicks deprived of left-eye vision for 2 hours. The immunohistochemical technique was used in the present study todetect and compare Jun expressed in HV and LOP after different time of visual deprivation. It was shownthat the 24 - hour deprivation of left - eye vision didnot have obvious effects on the stages of memory formation, and after 24 hours of visual deprivation, theexpression of Jun - like protein was greatly higherthan that of 2-hour visual deprivation, and the learning induced the expression of Jun - like protein at ahigh level especially in LPO after visual deprivation.
