Global view of the functional molecular organization of the avian cerebrum: mirror images and functional columns

Abstract: The last two authors contributed equally in co-supervising the project and conducting experiments. The second and last authors began this project originally as part of their graduate theses. ROLE OF AUTHORSEDJ, CCC, and KW performed experiments, quantifications, analyses, and wrote the article; JY, AP, CCC performed the computational analyses; MVR, HH, GF, OW, SCJ, ERJ, LK, SB, and ME performed gene expression experiments. SCJ also generated the 3D images and movies. AEPP processed and quantified images. CS an… Show more

“…5 B-D), implying that parrots have evolved a specific, previously unrecognized cerebrotype (43) distinguished by a higher number of neurons allocated to the subpallium. Because subpallial structures play an important role in sensory and motor learning and execution of motor behavior (15,44), we suggest that the relatively enlarged subpallium in large parrots is likely associated with their greater learning skills, including vocal learning, and enhanced foot and beak dexterity (5, 6, 13, 45).…”

“…Avian brains thus have the potential to provide much higher "cognitive power" per unit mass than do mammalian brains. amygdala) (14)(15)(16)41). The avian subpallium (formed by the striatum, pallidum, and septum), diencephalon, tectum, and brainstem were pooled and compared with the same regions of mammalian brains that are referred to as "the rest of brain."…”

“…Moreover, the two areas share important properties such as dense innervation by dopaminergic fibres and connectivity patterns with multiple sensory input, limbic and motor output regions 16 . However, the pattern of thalamic connections 22 as well as developmental gene expression patterns 23,24 and differences in macroarchitectures in birds versus mammals suggest that NCL and PFC are not homologous-that is, they independently evolved from different parts of the pallium 25,26 . Therefore, the avian NCL is considered to be a functional analogue of the mammalian PFC 14 , a structure with similar function but different evolutionary origin.…”

“…Thus, there are MelR-expressing brain areas which are not explicitly mentioned in the present work, in particular when expression is scattered. Anatomical descriptions were based on recent reviews of the nomenclature [Reiner et al, 2004;Chen et al, 2013;Jarvis et al, 2013].…”
