Agetsuma and colleagues find that the pathway between the lateral subnucleus of the dorsal habenula (dHbL) and the interpeduncular nucleus is involved in mediating experience-dependent fear responses in zebrafish. Genetic inactivation of the dHbL biased fish towards freezing, rather than the typical flight behavior, in response to a conditioned fear stimulus.
