“…Although the TO area is close to the TPO junction that is known to be related to neglect, it barely included the parietal areas. These parietal areas did not correlate with neglect severity, which supports a previous study [29] where the extent of parietal damage did not correlate with neglect severity. A study using CT scan also suggested that the temporal lobe (especially middle temporal) may be as important as the parietal lobe [30].…”

Neural Correlates of Hemispatial Neglect: A Voxel-Based SPECT Study

et al. 2010

Background: Despite many studies that investigated the neural correlates of hemispatial neglect (HN) with structural imaging, studies using voxel-wise analyses of functional imaging are not available. Furthermore, previous studies neither considered the neglect severity nor investigated whether there are differences in these neural correlates according to each neglect subtest. This study aimed to investigate the neural correlates of HN by correlating the total and the individual neglect score with hypoperfusion value on single photon emission computed tomography (SPECT) using voxel-wise analyses. Methods: Forty-two patients with acute right hemisphere strokes underwent a neglect test battery consisting of 3 bisection tasks, 2 cancellation tasks and 2 copying tasks. The SPECT images were acquired in these patients and 10 age- and education-matched normal controls. Results: Patients with HN, compared to those without HN, had hypoperfusion in the right middle temporal-occipital junction, inferior frontal gyrus and retrosplenial area. The total neglect score correlated with the hypoperfusion in the right middle temporal-occipital junction, fusiform gyrus, parahippocampal gyrus, inferior temporal gyrus, anterior part of the superior and middle temporal gyri, cuneus, lingual gyrus, angular gyrus, and the cerebellum. Across the neglect subtests similar correlation patterns were observed with minor variations. Conclusions: Unlike the results of previous studies showing that the critical neural correlates for HN are inferior parietal lobule or superior temporal gyrus, our study showed that the lesions that critically contribute to the neglect severity were located in the posterior parts of the middle temporal gyrus (temporal-occipital junction).

“…De Renzi & Spinnler (1966) suggested a right hemisphere bias for the Embedded Figures Test (EFT) as well as a greater sensitivity to anterior as opposed to posterior lesions (Egelko et al, 1988). Russo and Vignolo (1967) found that left hemisphere patients with aphasia also performed poorly on EFT whereas left hemisphere patients without aphasia performed like normal controls.…”

In this study three patients with unilateral focalized stroke lesions were examined longitudinally on the CAS subtests at 1 month and 6 months postinfarct such that each patient functioned as baseline. Patient 1 with a left temporal pole lesion had a severe syntactic comprehension deficit on Sentence Questions. Patient 2 had a rare right anterior cerebral artery (ACA) aneurysm culminating in a classical orbitofrontal syndrome and impairments on Expressive Attention, Word Series as well as a previously undescribed praxis-based figure ground reversal phenomenon on Figure Memory. Patient 3 suffered a right frontoparietal lesion with resulting representational as well as elements of motor neglect and impairments on Matching Numbers, Number Detection, and Receptive Attention. The three patient's lesions were all entirely consistent with the nature of cognitive neuropsychological symptoms suggesting that the CAS subtests are not only unique but also sensitive and specific to focalized cortical lesions.

“…Emotional processing at the behavioral level involves strategies (nonverbal, integrative, synthetic, holistic and gestalt) and functions (pattern perception, visuospatial organization and visual imaging) for which the neuroanatomical design and the neuropsychological organization of the right hemisphere are better suited [6]. The right cerebral hemisphere has been described as having greater ability to perform intermodal integration [9], greater interlobular organization [10], stimulus-evoked physiological activity [11] and functional interconnectivity among regions compared to the left hemisphere [12]. Heilman [13] suggested that the right hemisphere is more in touch with subcortical systems that are important for emotion processing.…”

Objective: Patients suffering from stroke have a diminished ability to recognize emotions. This paper presents a review of neuropsychological studies that investigated the basic emotion processing deficits involved in individuals with interhemispheric brain (right, left) damage and normal controls, including processing mode (perception) and communication channels (facial, prosodic-intonational, lexical-verbal). Methods: An electronic search was conducted using specific keywords for studies investigating emotion recognition in brain damage patients. The PubMed database was searched until March 2012 as well as citations and reference lists. 92 potential articles were identified. Results: The findings showed that deficits in emotion perception were more frequently observed in individuals with right brain damage than those with left brain damage when processing facial, prosodic and lexical emotional stimuli. Conclusion: These findings suggest that the right hemisphere has a unique contribution in emotional processing and provide support for the right hemisphere emotion hypothesis. Significance: This robust deficit in emotion recognition has clinical significance. The extent of emotion recognition deficit in brain damage patients appears to be correlated with a variety of interpersonal difficulties such as complaints of frustration in social relations, feelings of social discomfort, desire to connect with others, feelings of social disconnection and use of controlling behaviors.
