While a basal ganglia with striatal and pallidal subdivisions is1 clearly present in many
extant anamniote species, this basal ganglia is cell sparse and receives only a relatively …

Like non-peptidergic transmitters, neuropeptides and their receptors display a wide
distribution in specific cell types of the nervous system. The peptides are synthesized …

Somatostatin was first identified chemically in 1973, since when much has been established
about its synthesis, storage and release. It has important physiological actions, including a …

CSF-contacting (CSF-c) cells are present in the walls of the brain ventricles and the central
canal of the spinal cord and found throughout the vertebrate phylum. We recently identified …

The neural connections of the parapineal organ of two species of lampreys were studied
with the fluorescent dye 1, 1′‐dioctadecyl‐3, 3, 3′, 3′‐tetramethylindocarbocyanine …

Although brain organization in lampreys is of great interest for understanding evolution in
vertebrates, knowledge of early development is very scarce. Here, the development of the …

The habenula is an integrative center between the striatum and the limbic and motor
systems. With the aim of achieving further understanding of the evolution of this structure in …

The organization of the pallial derivatives across vertebrates follows a comparable
elementary arrangement, although not all of them possess a layered cortical structure as …

Publisher Summary This chapter provides an overview of the traits of the mammalian basal
ganglia (BG) that are pertinent to its identification in nonmammals. It reviews the modern …
