Neuroscience of consciousness

I am an associate Professor at the Department of Psychology, University of Bologna.

My research investigates the cognitive mechanisms and the neural correlates of visual perception, visuo-spatial attention and spatial representation both in neurologically intact individuals and patients with brain damage. My current primary interest is on the mechanisms mediating awareness in visual perception in patients with visual field defects. I am also focused on functional recovery and rehabilitation of visual disorders. To this aim, I use behavioural, neuropsychological and electrophysiological research methods.

My work is supported by projects grants from the Italian Ministry of Scientific Research and Education (MIUR).

Clinical Researcher

Francesco Di Gregorio

I got my M.S. in Neuroscience and Neuropsychology at the University of Bologna. Then I moved to Germany for my PhD at the University of Eichstätt-Ingolstand. In Germany, my research focused on electrophysiological correlates of error processing and conscious error awareness.

After my PhD I moved back to Italy at the University of Bologna where I started my collaboration with Prof. Vincenzo Romei. Our research focused on the study of oscillatory activity and EEG-based connectivity in conscious visual perception, attention and in at-risk populations, such as persons with accentuated schizotypy traits.

Currently, I am a clinical researcher at the AUSL of Bologna, where I am carrying out research activities in neurorehabilitation with stroke and traumatic brain injury patients. Moreover, I am part of a research team that studies electrophysiological and structural measures of brain connectivity in severe acquired brain injury and disorders of consciousness.

Research Assistant

Giuseppe Ippolito

I am a research assistant at the University of Bologna and the University of Udine, whose activities are supervised by Professors Vincenzo Romei and Cosimo Urgesi.

I completed my Bachelor’s degree in Psychological Sciences and Techniques in 2019, with an experimental thesis supervised by Prof. Alessio Avenanti. The topic focused on changes in motor cortical connectivity associated with aging, assessed using ccPAS techniques. I then earned my Master’s degree in Neuroscience and Neuro-Psychological Rehabilitation in 2022. For my experimental thesis, I worked with Professors Vincenzo Romei and Francesco Di Gregorio to develop a machine learning algorithm that predicts outcomes in patients with Disorders of Consciousness.

My research interests include the neural correlates of conscious experience in healthy individuals and altered states of consciousness. Currently, I am working on a project investigating how aprioristic beliefs and feedback shape our perception. To investigate this phenomenon, I explore and interfere with the brain’s oscillatory activity, combining EEG recordings with TMS techniques.

Visiting Fellow

Xisco Buades-Sitjar

PhD student in Education and Cognitive Processes at Nebrija University, Madrid. I have worked in research in a variety of fields -including criminal psychiatry, auditory language perception and differential psychology- in an attempt to explore everything that psychology research has to offer.
My interests have narrowed down to the use of electroencephalography and transcranial magnetic stimulation to help uncover the brain mechanisms underlying working memory, attention and visual perception, and to try to apply this knowledge to improve our education system. In particular, I am looking to explore the unique aspects of brain functionality in ADHD people, and how they differ from those of neurotypical people.

PHD Student

Riccardo Bertaccini

I’m a research assistant at the Center of Studies and Research in Cognitive Neuroscience, whose activity is supervised by Professor Vincenzo Romei.

After some years spent in engineering studies, in 2019 I obtained my BSc in Sciences and Psychological Techniques at the University of Bologna with a thesis concerning the physiological relationship between nasal respiration and pupil dynamics, developed during an exchange period spent at the Karolinska Institutet. Afterwards, in 2021 I earned my MSc in Neuroscience and Neuropsychological Rehabilitation at the University of Bologna, with a thesis entitled “Boosting working memory capacity by strengthening long-range alpha-band functional connectivity over the frontoparietal pathway”. Specifically, the project was aimed at assessing whether a novel oscillatory-based ccPAS protocol was able to enhance frontoparietal connectivity in the alpha band and, at the same time, be beneficial to working memory performance.

My research focus concerns the oscillatory dynamics underlying functional as well as resting state connectivity. That is why I’m currently following up on these findings, adopting a methodological approach that spans from non-invasive brain stimulation techniques to electrophysiological measurements, matched with behavioral or resting states paradigms.

Matteo Lai is a PhD student of the interdepartmental doctoral course in “Health and Technologies” at the Department of Electrical, Electronic, and Information Engineering “Guglielmo Marconi” with Professor Stefano Diciotti as supervisor and Professor Vincenzo Romei as co-supervisor.
His main research interests focus on deepening the knowledge of Autism Spectrum Disorders (ASD) through neuroimaging, EEG, genetics and clinical data. His research project aims to explain the continuum of ASD and perform classification against control subjects by exploiting generative adversarial networks-based frameworks. This will allow the extraction of imaging- and feature-based biomarkers through explainable AI techniques.

PhD Student

Gianluca Marsicano

I am a PhD student of the “Joint PhD program in Cognitive Neuroscience” at the Psychology Department of the University of Bologna. I obtained a master’s degree in “Neuroscience and Neuropsychological Rehabilitation” at the University of Padua. After graduation I did a post-graduate intern at “BDACLAB” of the Vita-Salute San Raffaele University under the supervision of Dr. Luca Ronconi. During my stay in the laboratory, I conducted EEG experiments on audiovisual integration processes and their underlying brain oscillatory activity, and studied these same mechanisms using web-based psychophysical paradigms. Furthermore, my research activity has been focused in investigating the EEG correlates of attentional zoom-lens anomalies in individuals with ASD using multivariate pattern analyses. Currently, I am carrying out my research activity in the Center of Cognitive Neuroscience in Cesena under the supervision of Prof. Caterina Bertini. My main research interests concerns the study of how the oscillatory brain activity drives visual and attentional performance in the healthy population, the study of how this neural activity is abnormal in patients affected by visual field defects and the investigation of how brain EEG oscillations can be functionally modulated with the use of sensory entrainment and NIBS techniques.

Jelena Trajkovic

I am a PhD student of the Joint PhD programe of Cognitive Neuroscience, Department of Psychology of the University of Bologna. Currently, I am carrying out my research activity in the Center of Cognitive Neuroscience in Cesena under the supervision of prof. Vincenzo Romei.

My research interest include describing electrophysiological underpinnings of processes of perception and attention. More specifically, understanding how the oscillatory brain activity in the alfa range is associated with both perceptual accuracy and subjective awareness, and, on the other hand, how it determines an efficient attentional control.

Furthermore, I am also interested in understanding and describing perceptual and attentional deficits in neurocognitive and psychiatric conditions, such as schizophrenia and autism, in the light of an abnormal functioning in the alfa range, by investigating at-risk populations, such as persons with accentuated schizotypy or autistic traits.

My research interests also include perfecting and developing novel protocols of combining neurostimulation techniques and electrophysiological measures, as well as integrating computational methods with traditional experimental approach.
