Previous accounts of mammalian brain allometry have relied largely on data from primates, insectivores and bats. Here we examine scaling of brain structures in carnivores, ungulates, xenarthrans and sirenians, taxa chosen to maximize potent...

Gonadotropin-releasing hormone (GnRH) is widely distributed in the brain of fishes where it may function as a neuromodulator of sensory processing and behavior. Immunocytochemical and neuronal label experiments were conducted on species fro...
Environmental complexity and social organization sculpt the brain in Lake Tanganyikan cichlid fish [0.03%]

Alexander A Pollen et al.
Complex brains and behaviors have occurred repeatedly within vertebrate classes throughout evolution. What adaptive pressures drive such changes? Both environmental and social features have been implicated in the expansion of select brain s...
Distinction of neurochemistry between the cores and their shells of auditory nuclei in tetrapod species [0.03%]

The distribution of Met-enkephalin (ENK), substance P (SP) and serotonin (5-HT) differs between the core and shell regions of the mesencephalic and diencephalic auditory nuclei of the turtle [Belekhova et al., 2002]. These neurochemical dis...
Variation in brain organization and cerebellar foliation in chondrichthyans: sharks and holocephalans [0.03%]

Kara E Yopak et al.
The widespread variation in brain size and complexity that is evident in sharks and holocephalans is related to both phylogeny and ecology. Relative brain size (expressed as encephalization quotients) and the relative development of the fiv...

Variation in relative eye size was investigated in a sample of 46 species of elasmobranch, 32 species of sharks and 14 species of batoids (skates and rays). To get a measure of eye size relative to body size, eye axial diameter was scaled w...
Arginine vasotocin promotes calling behavior and call changes in male túngara frogs [0.03%]

In the túngara frog, Physalaemus pustulosus, males alter calling behavior with changes in their social environment, adding 'chucks' to their advertisement calls in response to the calls of conspecific males. Other studies demonstrate that ...
Immunohistochemical organization of the forebrain in the white sturgeon, Acipenser transmontanus [0.03%]

The distribution of substance P (SP), leucine-enkephalin (LENK), serotonin (5HT), dopamine (DA), and tyrosine hydroxylase (TH) was examined in the forebrain of the white sturgeon in order to evaluate several anatomical hypotheses based on c...
Nerve ring of the hypostome in hydra: is it an origin of the central nervous system of bilaterian animals? [0.03%]

A hypothesis, 'the nerve ring in hydra shares a common origin with the central nervous system in bilaterian animals', is discussed in this review. The nerve ring of hydra is a ring of neurons whose neurites make a bundle running circumferen...

Although the basic swimming rhythm is created by central pattern generators (CPGs) located in each spinal segment, command signals from the brain should be indispensable for the activation of CPGs to initiate swimming. We hypothesized that ...
