CLINICAL CASE We describe the case of a man who, after a gunshot wound to the right facial region, exhibited chorioretinitis sclopetaria of the right eye and a contralateral homonymous hemianopsia. DISCUSSION Chorioretinitis sclopetaria is a rare entity resulting from an ocular injury caused by a bullet passing through the orbit. It is not common to find the condition associated with a damage...

INTRODUCTION Unilateral brain damage can heterogeneously alter spatial processing. Very often brain-lesioned patients fail to report (neglect) items appearing within the contralesional space. Much less often patients mislocalize items' spatial position. We investigated whether a top-down attentional load manipulation (dual-tasking), known to result in contralesional omissions even in apparently...

It has been proposed that behavior is influenced by representations of different types of knowledge: action representations, event knowledge, attitudes and stereotypes. Attitudes (representations of a concept or object and its emotional evaluation) allow us to respond quickly to a given stimulus. In this study, we explored the representation and inhibition of attitudes. We show that right dorso...

It has been maintained that 3-year-olds' difficulties in correctly predicting the undesired outcome of false beliefs reflects difficulties in interpreting the implications of conversations rather than a conceptual limitation in their theory of mind. As the right hemisphere has been seen to be responsible for the interpretation of the pragmatic aspects of communication, right-hemisphere-damaged ...

We attempted to determine whether schizophrenic patients can improve their performance on an abstract reasoning task through experience, and to ascertain how the degree of learning compares with brain-damaged patients and patient controls. Two hundred and two schizophrenic patients, 179 brain-damaged patients and 229 patient controls were compared with regard to their improvement on Subtest 6 r...

OBJECTIVE To evaluate the motor innervation of trunk muscles in traumatic brain injury patients. METHOD Twenty patients (12 men and 8 women) with traumatic brain injury were enrolled in this study. Their mean age was 41 years. Motor evoked potentials (MEPs) were performed on the motor cortex. Electromyographic activities were recorded from the bilateral rectus abdominis muscles, the external ...

Spatial cueing has been used by many different groups under multiple forms to study spatial attention processes. We will present evidence obtained in brain-damaged patients and healthy volunteers using a variant of this paradigm, the hybrid spatial cueing paradigm, which, besides single-target trials with valid and invalid cues, also contains trials where a target is accompanied by a contralate...

Temporal bone fracture and blunt head trauma was once considered as contraindication for the surgery. Increasing numbers of successful cochlear implantation are being reported. However, the outcome of cochlear implantation in severe damaged brain is unclear. A multichannel cochlear implant was successfully implanted in a 33-year-old man who had both sensorineural deafness, left hemiplegia due t...

In everyday life, the successful monitoring of behavior requires continuous updating of the effectiveness of motor acts; one crucial step is becoming aware of the movements one is performing. We studied the anatomical distribution of lesions in right-brain-damaged hemiplegic patients, who obstinately denied their motor impairment, claiming that they could move their paralyzed limbs. Denial was ...

The multidisciplinary team approach to the prolonged treatment of head injured patients in widely discussed. The rehabilitation process of the 147 subjects of this paper started while they were comatose and continued throughout the various stages of their progress towards full integration into society; the assessment of this process was carried out by testing their reintegration into work accor...
