What is lateralization of the brain?

Table of Contents

Lateralization of brain function. These areas frequently correspond to handedness, however, meaning that the localization of these areas is regularly found on the hemisphere corresponding to the dominant hand (anatomically on the opposite side). Function lateralization such as semantics, intonation, accentuation, prosody, etc.

What does the incisal surface of maxillary lateral incisors look like?

The incisal surface of the maxillary lateral incisors is almost identical to the corresponding surface on the maxillary central incisors. However, their labial and lingual convexities are more pronounced, hence it is not as straight or uniform. In addition, the incisal surface of these teeth can resemble small canines.

What is an example of lateralization in anthropology?

Specialization is much easier to observe as a trend, since it has a stronger anthropological history. The best example of an established lateralization is that of Broca’s and Wernicke’s areas, where both are often found exclusively on the left hemisphere.

What are the deciduous incisors?

The deciduous incisors are amongst the first teeth to erupt in an infant, appearing anywhere between 6 and 16 months of age. While the eight incisors share a common, general structure, various nuances differentiate them. This depends if they are central or lateral and mandibular or maxillary.

What is the evidence for lateralization at the population level?

The ESS theory predicts that lateralization at the population-level is more likely to have evolved in “social” rather than in “solitary” species. Studies conducted in different species of insects seem to be in alignment with this prediction. Shoaling and not-shoaling fishes have also provided evidence in support of this hypothesis.

What is the pathophysiology of auditory lateralization after right hemisphere lesions?

Based on these studies, there is converging evidence that disturbance of auditory lateralization is more frequent and more severe after right-hemisphere lesions. Across studies, the most consistent finding was that patients displaced lateralized sounds towards the side of the lesion, i.e., most frequently towards the right.
