Neural networks with biologically plausible accounts of neurogenesis
One of the reasons artificial neural net algorithms like cascade correlation (pdf) have been generating interest is because they start with a minimal topology (just input and output unit) and recruit ...

How are newly created neurons recruited into existing networks?
As far as I understand, the basics of neurogenesis (abstracted down to the level that makes sense to a computer scientist) is as follows:
Neural progenitor cells differentiate into new neurons that ...
