Although the sex-determining gene Sry has been identified in mammals, no comparable genes have been found in non-mammalian vertebrates. Here, we used recombinant breakpoint analysis to restrict the sex-determining region in medaka fish (Oryzias latipes) to a 530-kilobase (kb) stretch of the Y chromosome. Deletion analysis of the Y chromosome of a congenic(More)
Anticipation of danger at first elicits panic in animals, but later it helps them to avoid the real threat adaptively. In zebrafish, as fish experience more and more danger, neurons in the ventral habenula (vHb) showed tonic increase in the activity to the presented cue and activated serotonergic neurons in the median raphe (MR). This neuronal activity(More)
DMRT1, which is found in many vertebrates, exhibits testis-specific expression during the sexual differentiation period, suggesting a conserved function of DMRT1 in the testicular development of vertebrate gonads. However, functional analyses have been reported only in mammals. The current study focused on the Dmrt1 function in the teleost medaka, Oryzias(More)
A lognormal recurrent network model for burst generation during hippocampal sharp waves. Diesmann, Moritz Helias (2014) Spiking network simulation code for petascale computers. Excitatory and inhibitory STDP jointly tune feedforward neural circuits to selectively propagate correlated spiking activity.
