Disorders of vocal emotional expression and comprehension: The aprosodias
2021, Handbook of Clinical NeurologyCitation Excerpt :The verbal–linguistic deficits that do occur have been attributed to loss of executive control, the patient's thought disorder, or, possibly, a right hemisphere disturbance, such as preferentially interpreting words denotatively (using primary or literal definitions) as opposed to connotatively (using nonliteral or abstract definitions) (Cutting, 1990; Cutting and Murphy, 1990; Di Simoni et al., 1987; Mitchell and Crow, 2005). In addition, some research has suggested that loss of interhemispheric integration of cognitive functions via the corpus callosum might contribute to schizophrenic psychopathology (Merriam and Gardner, 1987; Raine et al., 1989; Coger and Serafetinides, 1990). In order to establish whether or not the affective-prosodic deficits in schizophrenia are, in fact, due to a right rather than a left hemisphere or callosal disturbance, Ross et al. (2001) compared the performance of Schizophrenic patients (n = 45) with LBD patients (n = 10), RBD patients (n = 9), and Controls (n = 19) using the repetition and comprehension tasks of the ApB.
Frontal white matter abnormalities reveal the pathological basis underlying negative symptoms in antipsychotic-naïve, first-episode patients with adolescent-onset schizophrenia: Evidence from multimodal brain imaging
2020, Schizophrenia ResearchCitation Excerpt :Our results are in line with the previous studies that the corpus callosum is abnormal in patients with schizophrenia(Kelly et al., 2018). For instance, changed structural properties, such as thicker corpus callosum(Coger and Serafetinides, 1990), and abnormal FA(Gu et al., 2016) and DTI dice values(Koshiyama et al., 2018) were reported associated with the negative symptoms in schizophrenia. The current results corroborated with these findings and provided a new perspective from the WM functional network.
White matter alterations in the corpus callosum of adolescents with first-admission schizophrenia
2012, Neuroscience LettersCitation Excerpt :The corpus callosum (CC) is the largest commissure of the human brain, connecting neocortical regions of the two hemispheres and playing a primary role in the sensory and cognitive integration of information. There is evidence of impairment in interhemispheric information transfer in schizophrenia [4], and numerous diffusion tensor imaging (DTI) studies of adults with schizophrenia have reported alterations in the CC. However, the results of these studies are inconsistent, some reporting decreases and others increases in fiber integrity measured in terms of fractional anisotropy (FA) [15,23].
