Sex differences in the relationship between planum temporale asymmetry and corpus callosum morphology in chimpanzees (Pan troglodytes): A combined MRI and DTI analysis.

Strikingly, the 3 regions showing positive correlations between CT and CSA asymmetries were those known to exhibit robust asymmetries across methodologies, such as the leftward asymmetrical planum temporale and the rightward asymmetrical superior temporal sulcus and cingulate cortex.

In studies of adults, Petitto has found that both hearing and deaf adults use the planum temporale — mainly on the left side — to process syllables, whether signing or speaking aloud.

The planum temporale «was clearly the part of the brain that was activated,» Petitto says, and the same was true for the 10 babies who were examined before Rebecca.

Within the left brain, Petitto has her sights set on the planum temporale, a piece of the superior temporal gyrus, which is a chunk of brain about the size and shape of an index finger that curves over the top of the ear.

The anatomical asymmetry of the planum temporale that hosts auditory functions is not a marker of the lateralization in the left hemisphere of language functions.

A region of the brain that extends through both hemispheres, the planum temporale, is larger in the left than in the right hemisphere.

«The results of the study show that the planum temporale does not explain the rare but strong individual variability of the language domain that exists in humans and, therefore, can not be considered as a marker of language asymmetry at individual level,» they stress.

In 1968, when there were no techniques to observe how the brain worked in vivo, the neurologist Norman Geschwind discovered in deceased persons that a region of the temporal lobe, the planum temporale, was larger in the left than in the right hemisphere.

Previous studies indicated that a brain region called the planum temporale (located above and behind the auditory cortex) is responsible for localizing sounds in space.

«It was important in my view to show that the planum temporale does its job even «behind the scenes» when you don't intend to listen or localize.»

Deouell plans to further study the planum temporale to see how close sounds can get to one another before the region interprets them as nondistinct and whether its activity can be overridden by another part of the brain, perhaps during a task that does not allow for any distraction.

In each case, whenever the location of a sound was modified, the subjects showed increased activity in their planum temporales; if the sound moved to more locations, heightened activity was elicited from the brain region.

New research now shows that the planum temporale activates automatically when there is noise, even if a person is not anticipating it.

By contrast, females on average had higher density in the left frontal pole, and larger volumes in the right frontal pole, inferior and middle frontal gyri, pars triangularis, planum temporale / parietal operculum, anterior cingulate gyrus, insular cortex, and Heschl's gyrus; bilateral thalami and precuneus; the left parahippocampal gyrus, and lateral occipital cortex.

The primary motor regions (BA4a and BA4p), the planum temporale (Wernicke's region: Te3), the ventral prefrontal cortex (Broca's region: BA44 and BA45), and the rostral inferior parietal cortex BA40 (merged PFop, PFt, PF, PFm, and PFcm) were spatially defined using probabilistic cytoarchitectonic maps using the SPM anatomy toolbox v. 1.6.

Brains from male cases with dyslexia show symmetry of the planum temporale and predominantly left - sided cerebrocortical microdysgenesis.

A decrease in CSA in the planum temporale was detected in cases with duplication in the left hemisphere.
