Authors Peru A, Moro V, Tellini P, Tassinari G. Abstract We describe the case of an 11-year-old, previously healthy, pre-puberal, right-handed girl with acquired aphasia following an extensive cerebral hemorrhage into a left hemisphere brain tumor. A 3-year follow-up evaluation of the girl’s…

Gravitational influences on reference frames for mapping somatic stimuli in brain-damaged patients.
Authors Peru A, Moro V, Sattibaldi L, Morgant JS, Aglioti SM. Abstract Previous studies have shown that the manipulation of body position in space can modulate the manifestations of visual neglect. Here, we investigated in right brain-damaged patients (RBD) the possible influence of gravitational…
Changes in spatial position of hands modify tactile extinction but not disownership of contralesional hand in two right brain-damaged patients.
Authors Moro V, Zampini M, Aglioti SM. Abstract Somatic misperceptions and misrepresentations, like supernumerary phantom limb and denial of ownership of a given body part, have typically been reported following damage to the right side of the brain. These symptoms typically occur…
Illusory movements of the contralesional hand in patients with body image disorders.
Authors Zampini M, Moro V, Aglioti SM. Abstract OBJECTIVES: In the present study, we assess whether illusory sensations of movement can be elicited in patients with right brain damage (RBD). METHODS: Ten RBD patients (three with disorders of bodily representations) were asked…
Dissociation between taste and tactile extinction on the tongue after right brain damage.
Authors Berlucchi G, Moro V, Guerrini C, Aglioti SM. Abstract In patients with right brain damage (RBD) or left brain damage (LBD) and healthy subjects, tactile and three basic gustatory stimuli (sour, salty, bitter) were applied to the left or right hemitongues or…
Temporary and permanent signs of interhemispheric disconnection after traumatic brain injury.
Authors Peru A, Beltramello A, Moro V, Sattibaldi L, Berlucchi G. Abstract The corpus callosum is frequently damaged by closed head traumas, and the resulting deficits of interhemispheric communication may vary according to the specific position of the lesion within the corpus callosum. This…
Tactile salience influences extinction.
Authors Aglioti S, Smania N, Moro V, Peru A. Abstract We delivered unilateral (left or right) or bilateral tactile stimuli to hands or feet of right-brain-damaged patients, six with tactile extinction and two without. Stimuli were simple touches or sliding stimuli directed proximo-distally…
Influence of perceptual and semantic conflicts between the two halves of chimeric stimuli on the expression of visuo-spatial neglect.
Authors Peru A, Moro V, Avesani R, Aglioti S. Abstract We investigated how perceptual and semantic relationships between the left and right half of chimeric stimuli influence overt and covert visual processing by asking eight right brain damaged (RBD) patients with hemispatial neglect…
Overt and covert processing of left-side information in unilateral neglect investigated with chimeric drawings.
Authors Peru A, Moro V, Avesani R, Aglioti S. Abstract Overt and covert processing of contralesional information was investigated in 6 right-brain-damaged (RBD) patients with or without left hemispatial neglect by using three bedside tests that require the analysis of whole, half, and…
