Localizing the human primary auditory cortex in vivo using structural MRI
Currently there are no routine methods to delineate the primary auditory cortex (PAC) of humans in vivo. Due to the large differences in the location of the PAC between subjects, labels derived from post-mortem brains may be inaccurate when applied to different samples of in vivo brains. Recent magnetic resonance (MR) imaging studies suggested that MR-tissue properties can be used to define the...
متن کاملLocalizing the primary auditory cortex using structural and functional MRI at 7 Tesla
The localization of the primary auditory cortex (PAC, i.e. the core areas) of humans in vivo and its delineation form the neighbouring belt areas is still an unsolved issue. There is only one fMRI study, performed at 7 Tesla, which convincingly revealed the mirror-symmetric tonotopic organization of two PAC fields (Formisano et. al 2004), however, this functional mapping approach has not develo...
متن کاملHeschl gyrus and its included primary auditory cortex: structural MRI studies in healthy and diseased subjects.
Despite the fact that the Heschl gyrus (HG) is a crucial brain structure as it contains the primary auditory cortex (PAC), relatively few structural MRI studies have concentrated upon it. We propose that this may be attributed in part to the considerable variability of this structure and, most importantly, to the lack of unified criteria for defining the extent of the PAC along the MRI-determin...
متن کاملEffective and structural connectivity in the human auditory cortex.
Language processing involves multiple neuronal structures in the human auditory cortex. Although a variety of neuroimaging and mapping techniques have been implemented to better understand language processing at the level of the auditory cortex, much is unknown regarding how and by what pathways these structures interact during essential tasks such as sentence comprehension. In this study, the ...
متن کاملHuman primary auditory cortex follows the shape of Heschl's gyrus.
The primary auditory cortex (PAC) is central to human auditory abilities, yet its location in the brain remains unclear. We measured the two largest tonotopic subfields of PAC (hA1 and hR) using high-resolution functional MRI at 7 T relative to the underlying anatomy of Heschl's gyrus (HG) in 10 individual human subjects. The data reveals a clear anatomical-functional relationship that, for the...
