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.

Visiting Researcher

Esteban Sarrias

I have a PhD in Psychology from the University of Seville (US), involved in investigating attentional alterations in patients with Multiple Sclerosis (MS) using electroencephalography (EEG). I have worked in Rome (Università degli studi di Roma “Foro Italico”) where I learnt to apply neural sources analysis on EEG signal. Firstly, I formed part of a team at the Institute of Applied Linguistic (ILA) belonging to the University of Cadiz (UCA). I managed a project about language disorders in children in which we applied simultaneous recording EEG and eye-tracker to describe the neural mechanism involved in the integration of visual and auditory stimuli during the syntactic and semantic processing. Afterwards, I joined the Psychophysiology and Neuroimage Group and INIBiCA institute, whose leader is Dr. Javier González Rosa. Thanks to my achievements, I was awarded a competitive postdoctoral “Juan de la Cierva-Formación”fellowship to continue researching on brain correlation of deep and transcranial neuromodulation in Parkinson Disease (PD) and MS. At the moment, I am expanding my knowledge and abilities to run studies with simultaneous recording EEG and transcranial magnetic stimulation (TMS). For this reason, I am a visiting researcher at the Center of Cognitive Neuroscience (Università di Bologna) in Cesena, under the supervision of Prof. Vincenzo Romei. My research interests include investigating and characterizing the brain mechanisms cortico-basal ganglia underlying cognitive function and dysfunction in both healthy subjects, MS and PD by using different functional neuroimaging techniques, such as high-density electroencephalography (EEG) and structural (MRI) and functional magnetic resonance imaging (fMRI) after application of transcranial magnetic stimulation (TMS).

PHD student

Giulia Benedetti

I completed my academic studies at the university of Bologna Alma Mater Studiorum, firstly obtaining a bachelor’s degree in Psychological Sciences and Techniques, and then a master’s degree in Neuroscience and Neuro-Psychological Rehabilitation. My master’s degree thesis focused on the concept of intentional binding in ventromedial prefrontal cortex (vmPFC) patients. I had the chance to spend two months at the Davis Center for Mind and Brain, California, contributing on the development of the experimental paradigm aimed to investigate visuospatial and temporal deficits that, according to literature, possibly underlie autism. I undertook a clinical internship at “Ausl della Romagna”, in the Department of Primary Care, primarily focusing on neuropsychological assessment, diagnosis, and rehabilitation of neuropsychological issues (due to various brain injuries). Currently, I started my PhD at the University of Nebrija, Madrid, in co-tutorship with the University of Bologna. I am interested in sense of agency, illusions of control and the process of attribution of causality.

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.
