This volume is a collection of articles written by Nobel Laureate Rita Levi-Montalcini and published from 1942 to 1995. Studies described in the first part set the stage for the discovery of a protein molecule which became known as the Nerve Growth Factor (NGF), described in detail in the second part. The NGF synthesized in minute amounts in all vertebrate tissues, plays an essential role in the differentiation and survival of several nerve cell populations in the peripheral and central nervous system. The discovery of the NGF was defined by the Nobel Foundation as a milestone in...

The past two decades may well become known as the golden era of neurobiology. This field, that in the first half of this century seemed far too complex to be investigated with the low resolution techniques available to the investigators, suddenly blossomed in the second half of the century into one of the most promising areas of biology, thanks to discoveries which took place practically simultaneously in most areas of neurobiological research. Here we mention only some of the most important: the discovery of the large number of neurotransmitters from monoamines to peptides, the...
