The brains of lungfishes have received little attention in comparative neuroanatomy, in spite of the strategic position of these fishes in phylogeny, in that they are currently recognized as the closest living relatives of tetrapods. The neglect has

Most biological homologues involve comparison of single characters in two or more taxa. It is possible, however, to recognize homologous characters between two or more taxa that involve the transformation of one character into many characters or many

The distribution of substance P-, leucine-enkephalin-, tyrosine hydroxylase-, and serotonin-like immunoreactivities was studied in the forebrain of the silver lamprey and compared to other vertebrate groups. In silver lampreys, substance P and leucin

A morphotype of the forebrain of gnathostomes, i.e. those characters that must have been present in the forebrain of ancestral gnathostomes, was generated by using out-group analysis to identify the s

Understanding the evolution of centralized nervous systems requires an understanding of metazoan phylogenetic interrelationships, their fossil record, the variation in their cephalic neural characters, and the development of these characters. Each of

A common pattern of distribution of neurons and fibers containing the calcium-binding proteins calbindin-D28k (CB) and calretinin (CR) in the spinal cord of terrestrial vertebrates has been recently demonstrated. Lungfishes are considered the closest

The retinofugal projections in the bowfin, a non-teleost actinopterygian, were studied by autoradiographic and horseradish peroxidase methods, and the cytoarchitecture of retinorecipient regions of th

The retinofugal and retinopetal connections in the green sunfish were studied by autoradiographic and horseradish peroxidase methods. All retinofugal fibers decussate in the optic chiasm. Some fibers project to contralateral preoptic and hypothalamic

The history of biology reveals numerous interpretations of the relationship between ontogeny and phylogeny, among them Garstang's critical realization that phylogeny can only be the history of changes in an ancestral ontogeny. One extrapolation of Ga

An outgroup analysis of multiple ontogenies provides the most robust approach to understanding phylogeny. Such an analysis of the lateral line system among extinct and extant gnathostomes reveals that lateral line placodes constitute the basic ontoge
