Nicotinic involvement in memory function in zebrafish.

Journal Article (Journal Article)

Zebrafish are an emerging model for the study of the molecular mechanisms of brain function. To conduct studies of the neural bases of behavior in zebrafish, we must understand the behavioral function of zebrafish and how it is altered by perturbations of brain function. This study determined nicotine actions on memory function in zebrafish. With the methods that we have developed to assess memory in zebrafish using delayed spatial alternation (DSA), we determined the dose effect function of acute nicotine on memory function in zebrafish. As in rodents and primates, low nicotine doses improve memory in zebrafish, while high nicotine doses have diminished effect and can impair memory. This study shows that nicotine affects memory function in zebrafish much like in rats, mice, monkeys and humans. Now, zebrafish can be used to help understand the molecular mechanisms crucial to nicotine effects on memory.
