 | | This process was accompained by major changes in the pattern of termination of some sensory afferents into the pallium, especially those sensory pathways that use the mesencephalon as a relay to access the thalamus. |  | | One important point in these considerations is that perhaps one of the major innovations in mammalian brain evolution was the confluence of the lemniscal and mesencephalic sensory pathways (especially visual) in the dorsal pallium, and their convergence in the amygdala and hippocampus. |  | | More specifically, in mammals the sensory pathways that relay in the mesencephalon (collothalamic) are directed to the dorsal pallium, while in reptiles and birds these pathways terminate in the ventral pallium. |

| | It's official - birds are brainy |
 | | Rather, fully 75 percent of a bird's brain is an intricately wired mass that processes information in much the same way as the vaunted human cerebral cortex. |  | | And behavioral studies in recent years have proved that many birds have more pallium power than your average mammal. |  | | As of today it is the "arcopallium," which means, in effect, "arched structure in a cognitively sophisticated area." |

 | | But they do propose to modify the concept, so that the emergence of intelligent thinking birds and their brains at least take their rightful place alongside the world's mammals and are not relegated to the role of dumb creatures, all instinct and no intelligence. |  | | The links between the brain evolution of birds and mammals have resulted from sophisticated new studies in brain imaging, genetic analysis and laboratory experiments tracing the pathways of the central nervous systems in the two widely separated animal groups, according to the findings of the international consortium. |  | | In their studies of the brain anatomy of birds and mammals, Jarvis and his colleagues have found many similarities that have long been unrecognized. |

 | | For example, the avian pallidum (PP) doesn’t seem to be divided into internal and external segments as it is in mammals ADDIN ENRfu (Reiner et al., 1998), and PA (or least caudalmost PA) lacks ChAT+ neurons ADDIN ENRfu (Medina and Reiner, 1994 and personal observations). |  | | As you know, this view has the telencephalon develop through patterning mechanisms that are conserved throughout amniotes, but with different developmentally defined compartments contributing to much of the pallium in adult mammals and birds (mammals: dorsal pallium; birds: ventral and lateral pallia). |  | | Something similar might happen in the patterning of the subpallium (molecular mechanisms as yet undefined), perhaps related to the shift in patterning in the pallium, perhaps independent of that. |

| | Avian Brain & Senses |
 | | "According to this theory, the avian cerebrum is almost entirely composed of basal ganglia, a structure involved only in instinctive behavior, and the malleable behavior thought to typify mammals exclusively requires the so-called neocortex," wrote the researchers. |  | | Modern consensus view of avian and mammalian brain relationships. |  | | Increasing sophistication in sensory processes, motor control, and behavior in reptiles and, particularly, birds over evolutionary time may have been the selective force driving the development and increasing volume of the avian pallium. |

| | Gene Expression: Birds not so 'bird-brained' after all |
 | | This realization of a relatively large and well developed avian pallium that processes information in a similar manner to mammalian sensory and motor cortices sets the stage for a re-evaluation of the cognitive abilities of birds.... |  | | These illustrations [taken from the press release] compare the traditional view of the primitive avian brain as a subregion of the human brain (in purple) with the new view that the avian brain has subregions proportional to those in humans (blue, purple and green). |  | | All in all, this new awareness and further understanding of the cognitive abilities of birds should provide us with new ways to think about how we think. |

| | Evolution of the Amniote Brain |
 | | Several distinct types of neurons have been recognized in different avian species, but most neurons can be characterized as having stellate-shaped dendritic trees with varying numbers of spines. |  | | The tectum of the mesencephalon is an important visual structure in the amniote visual system. |  | | Avian ADVR organization, in conjunction with the outdated "-striatum" designation for avian forebrain structures, may unnecessarily confuse comparisons of neuroanatomy and function of amniote sensory systems. |

 | | The structures developed from the three stem-vesicles (metencephalon, mesencephalon and diencephalon), -- i.e., the oblongata, the quadrigemina and the thalami, -- and the fibre-systems that ascend among them from the myel, are grouped together in the nomenclature of the developed brain as the caudex or brain-stem. |  | | The avian cerebellum has no pilea, and so appears, in dorsal aspect, as an unpaired structure of a more or less spherical or ovoid form. |  | | The convolution of the cerebellum is found in its simplest form in the birds. |

 | | In the anatomy of animals, an avian pallium is the dorsal telencephalon of a birds brain. |  | | Except during copulation, it is hidden within the proctodeum compartment within the cloaca, just inside the vent. |  | | The avian phallus differs from the mammalian penis in several ways, most importantly in that it is purely a copulatory organ and is not used for dispelling urine. |

| | Bird song - Wikipedia, the free encyclopedia |
 | | Birdsong learning occurs along neural pathways that connect the Hyperstriatum Ventralis, which is a region unique to the avian pallium, to the robust nucleus of the Archistriatum. |  | | The anatomical and physiological mechanisms underlying the production of bird song, the acquisition of song during the life of individual birds, the acoustic structure of the songs, and their adaptive function in the social life of birds, have been the subject of intensive scientific study. |  | | Research has hypothesized learned songs allow the development of more complex songs through cultural interaction, it allows interaspecies dialects that help birds stay with their own kind within a species, and it allows birds to adapt their songs to different acoustic environments. |

 | | Cal State Long Beach Psychology Professor Diane Lee is one reason why "birdbrain" won't mean stupid anymore. |  | | The consortium has recommended many changes especially to the those incorrectly named striatal structures; such changes as renaming the avian brain region called the "archistriatum" as the "arcopallium," (arched pallium) to emphasize the fact that this region is neither "archaic" nor part of the basal ganglia. |  | | Lee wanted to be a part of the research since its beginning in 1997. |

 | | A patch/matrix type of organization also has recently been found in the ventral hyperstriatum and the neostriatum of the chicken pallium, where cell clusters of similar birthdates (''isochronic'' clusters) are surrounded by a matrix of cells that are born at a different time. |  | | Cadherins are known to mediate the aggregation and sorting of cells during development in many organs. |  | | Their differential expression by isochronic cell populations in the mammal subpallium and avian pallium suggests a common morphogenetic mechanism that regulates the formation of the patch/matrix patterns in these regions. |

| | EVOLUTION: ON THE MENTALITY OF CROWS |
 | | This enlargement of the "avian prefrontal cortex" may reflect an increase in primate-like intelligence in corvids. |  | | Recent experiments investigating the cognitive abilities of corvids have begun to reveal that this reputation has a factual basis. |  | | These studies have found that some corvids are not only superior in intelligence to birds of other avian species (perhaps with the exception of some parrots), but also rival many nonhuman primates. |
