“…Improvement of body representation deficit after tumor resection has been occasionally reported previously. In particular, patients with meningiomas in the parietal–occipital areas that showed impairments in body-related tasks, such as left–right orientation, recovered their functions once the tumor was removed (Nikishina et al 2016 ). Partial recovery was observed on a patient who showed a severe misoplegia toward her left leg, after the removal of a tumor in the right medial and temporoparietal lobes (Loetscher 2006 ).…”

Selective effects of a brain tumor on the metric representation of the hand: a pre- versus post-surgery comparison

Body representation disorders are complex, varied, striking, and very disabling in most cases. Deficits of body representation have been described after lesions to multimodal and sensorimotor cortical areas. A few studies have reported the effects of tumors on the representation of the body, but little is known about the changes after tumor resection. Moreover, the impact of brain lesions on the hand size representation has been investigated in few clinical cases. Hands are of special importance, as no other body part has the ability for movement and interaction with the environment that the hands have, and we use them for a multitude of daily activities. Studies with clinical population can add further knowledge into the way hands are represented. Here, we report a single case study of a patient (AM) who was an expert bodybuilder and underwent a surgery to remove a glioblastoma in the left posterior prefrontal and precentral cortex at the level of the hand’s motor region. Pre- (20 days) and post- (4 months) surgery assessment did not show any motor or cognitive impairments. A hand localization task was used, before and after surgery (12 months), to measure possible changes of the metric representation of his right hand. Results showed a post-surgery modulation of the typically distorted hand representation, with an overall accuracy improvement, especially on width dimension. These findings support the direct involvement of sensorimotor areas in the implicit representation of the body size and its relevance on defining specific size representation dimensions.

Body scheme plays an important role in the development of educational skills such as reading and writing, visual-spatial thinking, spatial gnosis, optical-spatial strategies. Children of primary school age with hearing impairment have left hemispheric and right hemispheric insufficiency, difficulties in interhemispheric interaction and the integrity of perception. This hinders their full integration into the educational process and reduces their adaptive abilities. The study of the body scheme in hearing impaired children of primary school age was the goal of an empirical work, and a hypothesis was the assumption of the existence of features of its structural organization. Respondents aged 8,97±0,76 years (N=60) participated in the study. 30 hearing impaired primary schoolchildren (12 female children and 18 male children) were included in the experimental group and 30 junior schoolchildren without hearing impairments (14 female children and 16 males) entered the control group. Neuropsychological tests were used to assess the neuropsychological parameters of the body scheme. The results obtained attest to the features of the body scheme in hearing impaired children of primary school age. It was found that the ideas about their own body, the organization of movements in relation to the body scheme and the perception of space in children with hearing impairments are formed to a lesser extent than in children of the control group.

The study of neuropsychological features that cause eating disorders may provide a starting point for planning complex studies that allow for integral assessment of the internal and external mechanisms and patterns of eating disorders. The work aims to evaluate the influence of the neuropsychological status on features of the body schema in eating disorders. We conducted an analysis of the subjective and objective indicators of the body image on 51 women aged 20–35 years using face-relative hand position reproduction tests, the "Silhouette" method, measurement of the right hand index finger diameter and of the foot length, and a self-image questionnaire. We carried out qualitative and quantitative assessment of the neuropsychological status using the Luriev test battery. For the analysis of control functions, we used the Wisconsin sorting card test, Cantidad-Numér interference task (Canum), and "Block Span". We found that women with atypical eating behaviors noted the following features associated with a subjective attitude towards their own body: prevalence of dissatisfaction in one's emotional evaluation due to the perception of one's own appearance, stemming from the beliefs and ideas about one's ideal appearance, despite the absence of the abnormalities associated with the objectified ideas of one's own body (weight, size, body proportions). We identified modal-nonspecific control function deficiencies characteristic of different types of eating disorders.
