It is suggested that laterality evolved as a response to the demands of language and the need for air-based communication which may have necessitated a division of labor between the hemispheres in order to avoid having duplicate copies in both the Hemispheres that would increase processing redundancy.

A vision of graded hemispheric specialization

Empirical evidence is summarized that supports the claims that hemispheric lateralization is graded rather than binary and that this graded organization emerges dynamically over the course of development.

Hemispheric Asymmetry in Perception: A Differential Encoding Account

It is shown that both processing differences and differential frequency filtering can arise naturally in this neurocomputational model with neuroanatomically inspired differences in connection structures within the two model hemispheres, suggesting that hemispheric asymmetry in the processing of local and global features may be due to hemispheric asymmetries in connection structure rather than in frequency tuning.

Myeloarchitectonic Asymmetries of Language Regions in the Human Brain

This study reveals for the first time a mixed pattern of myeloarchitectonic asymmetries, which calls for a general theory to accommodate the full complexity of principles underlying human hemispheric specialization.

Anatomical Specialization of the Anterior Motor Speech Area: Hemispheric Differences in Magnopyramidal Neurons

A larger sample of cases is examined to determine how consistently this difference is present in the population, if it is specific to Broca's area or is a general feature of cortical regions mediating lateralized functions, and whether the subpopulation of large magnopyramidal neurons in left area 45 can be distinguished by their chemical phenotype.

Temporal processing asymmetries between the cerebral hemispheres: evidence and implications.

A large body of research which has investigated the capacities of the cerebral hemispheres to process temporal information supports the notion of a left hemisphere advantage for temporal resolution and demonstrates that cerebral lateralisation is not limited to the higher-order functions.

Interhemispheric asymmetries of the modular structure in human temporal cortex.

The present data suggest that more functionally distinct columnar systems are included per surface unit in the left than in the right area 22, suggesting similar relations between functional and anatomical architecture as in visual cortex.

The hypothesis that nerve cells in middle layers of the cortex should be joined by narrow vertical connections to cells in layers lying superficial and deep to them, so that all cells in the column are excited by incoming stimuli with only small latency differences is formulated.

Subdivisions of AuditoryCortex and Levels of Processing in Primates

The results indicate that auditory processing involves 15 or more cortical areas, each of which is interconnected with a number of other fields, especially adjoining fields of the same level.

The Minicolumn and Evolution of the Brain

Comparative studies are marred by a lack of standardized techniques, tissue preparation, cortical regions, or anatomical feature studied, however, recent advances in methodology enable standardized, quantified comparisons of minicolumn morphology.

Hemispheric differences in layer III pyramidal neurons of the anterior language area.

The presence of a unique population of large pyramidal neurons in left Brodmann's area 45 may be related to the involvement of this region in the circuitry that mediates motor speech functions.
