RESEARCH INTERESTS
The research is mainly focused on integration of multi-sensory inputs (vision, touch, proprioception, hearing, vestibular) in order to represent the body and the space. At the moment, the research has an important application in studying whether and how multisensory integration can be applied to rehabilitation of unisensory deficits, such as hemianopia. In particular, the relationship between recovery of hemianopia and oculo-motor system and the phenomenon of blind-sight in hemianoptic patients have been studied. Another research topic is investigating mechanisms underlying neglect rehabilitation by prism adaptation. In addition, by combining techniques including behavioral assessments, psychophysiological responses, and the investigation of patients with brain lesions recently we investigate the complex interactions between learning, emotion and the human brain.

Key words: multisensory; space; blind-sight; eye movements; neuropsychology; cognitive rehabilitation.

PhD PROJECTS
1) Unconscious visual processing and blindsight
“Blindsight” refers to the ability of some cortically blind patients to discriminate visual events presented within their scotoma, despite being unaware of the visual stimulation. Possible neural mechanisms responsible for visual residual functions are still under debate. Two main neural pathways have been identified in the visual system: the retino-geniculate-striate pathway, responsible for conscious identification of stimuli and the retino-tectal-extrastriate pathway, involved in automatic stimuli localization. The retino-tectal-extrastriate pathway includes also subcortical structures involved in eye movements generation, such as the superior colliculus. The aim of the project is to investigate a possible role for these structures in mediating blindsight. The project will combine neuropsychological and psychophysics methods with eye movements recordings, EEG recordings and transcranial magnetic stimulation.

2) Audio-visual integration in hemianopic patients
Patients with visual field defects often exhibit impairments in visual exploration and a typical defective visual scanning behaviour. It has been showed that a training based on a systematic audio-visual stimulation can improve patients’ visual search abilities. The purpose of the project is to study the mechanism underlying the amelioration of visuo-spatial disorders following the treatment by combining neuropsychological assessments, eye movements recordings, EEG recordings and lesions study.

3) Affective processes and related disorders
The aim of this research is to understand how the brain learns and stores information about danger. Using Pavlovian threat (fear) conditioning and other experimental paradigms, we investigate the mechanisms through which conscious emotional feelings, as opposed to behavioral or autonomic responses, come about. Some of the techniques we use to explore threat memory in the brain include brain lesions (patients with amygdale lesion), EEG and eye movements recording in healthy human volunteers (subjects with high and low alexitimia) and in patients with fear/anxiety disorders.
