Focusing on the neural pathway from the brain's prefrontal cortex to the amygdala, they combined optogenetics — a technique that uses light to control the activity of neurons in living tissue — with behavioral testing, a methodology that allows researchers to study functional connections between different regions of the brain.

Scientists believe these neural stem cells secrete hormonal steroids or proteins that nurse ailing neurons, preventing them from dying, and stimulate the formation of blood vessels that nourish damaged tissue with nutrients and oxygen.

By comparing how fast the neural circuits in the retina perform image - processing operations with how many instructions per second it takes a computer to accomplish similar work, I believe it is possible to at least coarsely estimate the information - processing power of nervous tissue — and by extrapolation, that of the entire human nervous system.

The authors note that the formation of each different organ bud type may require some fine tuning to optimize tissue self - organization, and further addition of neural cell types may be necessary, but this research may soon provide exciting model systems for the study of basic biology and pathology as well as providing appropriate replacement tissues for the treatment of many patients with no other viable options.

Genetic approaches in mouse model systems combined with cell biological assays have allowed Professor Lukas Sommer to identify mechanisms regulating stem cell fates in the developing CNS and in neural crest - derived tissues.
