Parietal versus temporal lobe components in spatial cognition: Setting the mid-point of a horizontal line
2009
Recent anatomo-clinical correlation studies have extended to the superior temporal gyrus, the right hemisphere lesion sites associated with the left unilateral spatial neglect, in addition to the traditional posterior-inferior-parietal localization of the responsible lesion (supramarginal gyrus, at the temporo-parietal junction). The study aimed at teasing apart, by means of repetitive transcranial magnetic stimulation (rTMS), the contribution of the inferior parietal lobule (angular gyrus versus supramarginal gyrus) and of the superior temporal gyrus of the right hemisphere, in making judgments about the mid-point of a horizontal line, a widely used task for detecting and investigating spa…
THE INFLUENCE OF SPATIAL COGNITION IN THEORY OF MIND AND CENTRAL COHERENCE TASKS: STUDY IN AUTISM
Autism Spectrum Disorder (ADS) is a severe developmental disability characterized by impairments in social interaction and communicative skills. Despite a growing research interest in the field, the causes of these impairments remain unknown. Two lines of research, Theory of Mind (ToM) and Central Coherence (CC), using experimental tasks such as visuo-spatial perspective Taking (VPT) and the local and global levels have suggested that visuo-spatial attention and spatial variables in the self-versus other recognition, may be the basis of the cognitive processes underlying social interaction. According to spatial attention, such as observed in the Unilateral spatial neglect (USN) may contribu…
Autobiographical memory and the self in a single-case of chronic unilateral spatial neglect
2016
International audience; Unilateral spatial neglect (USN) is mainly defined as a condition affecting perception and the mental representation of the environment. However, nothing is known about its impact on the ability to mentally represent one's past and on personal identity. We addressed these questions in a case of chronic USN, DR, a 59-year-old right-handed woman, who underwent a variety of measures exploring the self and autobiographical memory (AM). DR showed preserved self-images and her AM performance was only preserved when memories were prompted by her own self-images and not by self-unrelated cues. Our findings are discussed in light of the interconnection between the self and AM.
