“Since the discovery in
1996 that a region within caudal parahippocampal cortex subserves learning and recall of topographical information, numerous studies aimed at elucidating the structures and pathways involved in scene recognition have been published. Neuroimaging studies, in particular, SN-38 cell line have revealed the locations and identities of some of the principal cortical structures that mediate these faculties. In the present study the detailed organization of the system is examined, based on a meta-analysis of neuroimaging studies of scene processing in human subjects, combined with reviews of the results of lesions on this type of processing, single neuron studies, and available hodological data in non-human primates. A cortical hierarchy of structures that mediate scene recognition is established based on
these data, and an attempt is made to determine the function of the individual components of the system. (C) 2010 Elsevier Ltd. All rights reserved.”
“We evaluated hemispheric lateralization of language production in non-right-handed (NRH) patients with schizophrenia compared with matched right-handed see more (RH) patients, NRH control, and RH control subjects. First, the ability to generate verbs during overt training trials was checked in 78 subjects. They were then evaluated with functional magnetic resonance imaging (fMRI) while performing a covert verb generation task. No significant interactions between illness and handedness and no illness effect were observed in functional asymmetry. There was significantly less leftward asymmetry of the inferior frontal, precentral, and supramarginal gyri as well as the intra-parietal sulcus in non-right-handers compared to right-handers taking into account the task performances. Our findings suggested that decreased lateralization for language production was more closely related to handedness than to schizophrenia. (C) 2010 Elsevier Ltd. All rights reserved.”
predominance of the left hemisphere in language comprehension and production is well established. More recently, the right hemisphere’s contribution to language has been Sitaxentan examined. Clinical, behavioral, and neuroimaging research support the right hemisphere’s involvement in metaphor processing. But, there is disagreement about whether metaphors, in and of themselves, engage the right hemisphere or if other factors that vary between metaphors and literal language elicit right hemisphere engagement. It is important to disambiguate these issues to improve our basic knowledge of figurative language processing, to more precisely define how the right hemisphere supports language, and to facilitate our ability to understand and treat language impairments.
