Variability in Ostariophysan Fish Brain Anatomy in Relation to the Neural Pathway of Innate Fear Response

Abstract

Our research has focused on Zebrafish (Danio rerio) and Creek Chub (Semotilus atromaculatus), two species which have distinguished applications in the inquiry of the alarm response. While Zebrafish are easily bred have a widely established genome, the Creek Chub is larger (thus more easily manipulated) and shows variation in size and alarm response behavior between juveniles and adults.
