Transgenic animals expressing reporter genes in specific classes of neuronal cells are powerful tools for e study of neuronal network formation. We generated a wide variety of transgenic zebrafish at expressed reporter genes in specific classes of neurons or neuronal progenitors. ese include lines in which neurons of. Interestingly, ere are many neuron-specific promoters (in Drosophila, zebrafish or mice) at can be used to direct transgene expression into selected brain areas. For example, in Drosophila ere are promoters or drivers an can be used to express transgenes selectively in projection neurons in e antennal lobe (Stocker et al., 1997). e facial branchiomotor neurons (FBMNs) undergo a characteristic tangential migration in e vertebrate hindbrain.

Understanding neuron development. Zebrafish embryos are transparent, have a relatively simple nervous system, and develop quickly, all of which makes em highly useful to investigate how neurons (nerve cells) develop. In particular, our scientists use zebrafish to study e development of axons at are wrapped in a substance called myelin. Altered cortical excitability and synapse dysfunction are early pa ogenic events in amyotrophic lateral sclerosis (ALS) patients and animal models.
