I will review recent observations on the production and replacement<br />of neurons in the adult avian brain. I will highlight the fact that<br />the new neurons are temporary, that they replace older ones that<br />have died, and that the spontaneous replacement of neurons calls<br />for a new theory of long-term memory. This theory is new only in<br />relative terms, for it was first proposed 17 years ago (Nottebohm,<br />1984, 1985).
