Nerve Growth-Promoting Activities in Embryonic and Adult Tissues,like activity in the rat iris and sciatic nerve obtained by bioassay is reviewed. Data are presented to indicate that the iris of the adult chick can also produce a NGF-like factor in culture. It is described that many tissues from the rat and embryonic chick contain additional substances eliciting

Macromolecular Factors Involved in the Regulation of the Survival and Differentiation of Neurons Duns are initially produced in excess and that the subsequent selective neuronal death occurs as a normal event (Cowan, 1973; Jacobson, 1978). The topographically selective regulation of survival is an important mechanism for the formation of the final structure and function of integrated neuronal sys

Semantics and Neural Development, due to the focus of its founders on the concept of “genetic information”. As was spelled out thirty-five years ago by Erwin Schrô’dinger (1945) in his seminal book ., the gene can be viewed as an information carrier whose physical structure corresponds to an aperiodic succession of a small number o

Precursor

Development of Peptide Immunoreactivity in the Hippocampus, Visual Cortex and Retina,t least twenty peptides have been described in the brain and periphery, each belonging to seemingly morphologically distinct systems and each presumably playing distinct functional roles (Emson, 1979; Hokfelt et al., 1980; Walsh, 1981). The majority of studies have examined adult tissues; there are

The Embryonic Development of the Cerebral Cortex: What Can We Learn from Reptiles?,akic, 1978). Neuronal precursors proliferate into germinative zones, lining the ventricles (ventricular zones: VZ); post mitotic elements migrate outward, along radial glial guides, and the majority of them settle into the telencephalic cortical plate (CP).

Mutation-Induced Disorders of Mammalian Forebrain Development,l, 1965; Caviness and Rakic, 1978). A few of these appear to involve a relatively small number of cellular events of development. The effect of the mutation may appear to be restricted to a given region or even to a given neural system in some instances. The present review is concerned with three gr
