The evolutionary process works by modifying pre-existing mechanisms, which makes
continuity likely. A review of the evidence available to date suggests that there are many …

In birds, the nucleus of the basal optic root (nBOR) and the nucleus lentiformis
mesencephali (LM) are brainstem nuclei involved in the analysis of optic flow. A major …

In this paper, we propose a method to test alternative hypotheses of phenotypic evolution.
The method compares patterns observed in phylogenetic character data with patterns …

Constancy Functions and Gestalt Perception. A very peculiar and, in the highest organisms,
extremely important cognitive function, which involves an equally peculiar form of sensory …

Rats were trained in a lateralized reaching motor task during either anearly'(22–31 days old)
or alate'(62–71 days old) postnatal period. Thelate'group showed significant neuronal …

The present review covers all the published data on neuron death in the developing avian
isthmo–optic nucleus (ION), which provides a particularly convenient situation for studying …

There has been a long debate about a possible homology between parts of the dorsal
ventricular ridge (DVR) of reptiles and birds, and parts of the mammalian isocortex …

In anamniotes, the dorsal thalamus comprises:(1) a caudal division, the collothalamus,
which receives its predominant input from the midbrain roof and projects ipsilaterally to the …

Behavioral and Brain Sciences 24:2 Page 1 1. Introduction When we speak of brain evolution,
what exactly do we imagine to be evolving? This is not a trick question. Natural selection, after …

Retinotectal projections were studied in 33 different species of Actinopterygii, the ray-finned
fishes, with horseradish peroxidase and cobalt tracing techniques. The distribution of …
