Among the best-known facts of the brain are the contralateral visual, auditory, sensational, and motor mappings in the forebrain. [...] Key Result We show that such compensatory migratory movements can indeed be observed in the zebrafish (Danio rerio) and the chick (Gallus gallus). With a model we show how the axial twist hypothesis predicts that an optic chiasm should develop on the ventral side of the brain, whereas the olfactory tract should be uncrossed.Expand

The neural pathway midline crossing theory: a historical analysis of Santiago Rámon y Cajal's contribution on cerebral localization and on contralateral forebrain organization.
TLDR
A better understanding of the molecular and genetic substrates of the midline crossing processes might result in significant clinical advances in brain plasticity and repair and the evolutionary connection between fiber decussation and cortical function lateralization remains a mystery to be solved.
Opposite asymmetries of face and trunk and of kissing and hugging, as predicted by the axial twist hypothesis
TLDR
It is concluded that humans (and all other vertebrates) are fundamentally asymmetric, both in their anatomy and their behavior, which supports the thesis that the approximate bilateral symmetry of vertebrates is a secondary feature, despite their being bilaterians.
Somatic twist: a model for the evolution of decussation.
TLDR
Decussation evolved as a byproduct of a genetically determined partial inversion of the body plan, which resulted in a 180 degree rotation posterior to the brain and oropharynx.
Decussation as an axial twist: A comment on Kinsbourne (2013).
TLDR
Kinsbourne proposes one 180° turn while Kinsbourne considers the 180° being the result of two 90° turns in opposite directions, and the similarities and differences are discussed.
Commissural axon guidance in the developing spinal cord: from Cajal to the present day
TLDR
This review begins by giving a historical overview of the ventral commissure and the evolutionary purpose of decussation, then reviews the axon guidance studies that have revealed a diverse assortment of midline guidance cues, as well as genetic and molecular regulatory mechanisms required for coordinating the commissural axon response to these cues.
Another Look into the Central Nervous System Decussation Reveals A New Model for Evolution
Most large fibers in central nervous system of vertebrates are decussated. The cause or the evolutionary force of this phenomenon is not convincingly described. Here we show a pattern for this
Lateralization influences contest behaviour in domestic pigs
TLDR
The results suggest that cerebral lateralization may aid in conflict resolution, but does not directly contribute to fighting ability, and will be of value in the study of animal contests.
Evidence for absence of bilateral transfer of olfactory learned information in Apis dorsata and Apis mellifera
TLDR
It is shown that the olfactory system on each side of the bee can learn and retrieve information independently and the retrieval using the antenna on the side contralateral to the trained one is not affected by the training.
Evidence for absence of bilateral transfer of olfactory learned information in Apis dorsata and Apis mellifera
TLDR
It is shown that the olfactory system on each side of the bee can learn and retrieve independently and the retrieval using the antenna on the side contralateral to the trained one is not affected by the training.

The inversion hypothesis: A novel explanation for the contralaterality of the human brain
TLDR
It is shown that the eye indeed appears to be the inverting culprit based on this author's entirely original, but untested, concept of a cyclopean origin to vertebrates at a time when single-eyed chordates were evolving to double-eyed agnathan fish.
Variations in the architecture and development of the vertebrate optic chiasm
TLDR
This review aims to highlight key issues in the organisation and development of the vertebrate optic chiasm with a focus on comparing and contrasting the data that has been gleaned to date from different vertebrate groups.
The ups and downs of holoprosencephaly: dorsal versus ventral patterning forces
TLDR
It is suggested that two distinct mechanisms underlie the major classes of HPE, ‘classic’ and midline interhemispheric (MIH), while disruption of the dorsalizing effect of bone morphogenetic protein signaling may be key to cases of MIH HPE.
Reaching beyond the midline: why are human brains cross wired?
The crossing of nerve tracts from one hemisphere in the brain to the contralateral sense organ or limb is a common pattern throughout the CNS, which occurs at specialised bridging points called
Brain neurons which project to the spinal cord in young larvae of the zebrafish
TLDR
A small number of brain neurons project to caudal levels of the spinal cord in the larva of the teleostydanio rerio by backfilling with horseradish peroxidase following transection of the cord at the level of the cloaca.
A dynamic fate map of the forebrain shows how vertebrate eyes form and explains two causes of cyclopia
TLDR
A new model for forebrain neurulation is postulate and it is demonstrated how mutations affecting two signalling pathways can generate cyclopic phenotypes by disrupting normal cell movements or introducing new erroneous behaviours.

TLDR
The present findings show that the ventrolateral optic nucleus exhibits homological features of the dorsal lateral geniculate nucleus in other vertebrate groups, whereas the lateral genICulate nucleus of the nurse shark is much more comparable to the nucleus rotundus of teleosts and birds and would be more appropriately so named.
Unveiling the establishment of left–right asymmetry in the chick embryo
TLDR
A number of early and late events in the determination of left-right asymmetries that are currently poorly understood are pointed out and it is anticipated that the availability of the chick genome sequence will be combined with multidisciplinary approaches from experimental embryology, biophysics, live-cell imaging, and mathematical modeling to boost up knowledge ofleft-right organ asymmetry in the near future.
The Lobula-Complex of the Fly: Structure, Function and Significance in Visual Behaviour
TLDR
There is strong evidence that the lobula plate is the main motion computation centre of the optic lobe controlling the optomotor responses of the fly.
The Central Nervous System of Hagfishes
TLDR
The unique organization of myxinoid brains, long known from descriptive analyses, has more recently become the subject of experimental studies which show the pattern of retinal, lateral line, inner ear, trigeminal, and vagal projections while also defining many of the afferent and efferent connections of the olfactory bulbs, the palliai laminae, the mesencephalic tectum and part of the central prosencephalics nucleus.
