Franco CaudaFranco

Prof. Franco Cauda’s research focuses on:
I) Pathoconnectomics – This discipline studies how brain disorders impact on brain connectivity patterns, so as to better understand the relationship between brain alterations (considered from both the functional and structural perspectives) and brain disorders, as well as to find out how brain alterations spread within cerebral regions by identifying their propagation patterns and mechanisms.

II) Brain connectivity – This research area concerns the study of how different brain areas connect with each other and interact. The methodology used for these investigations can construct anatomical or functional maps, as well as models of causal interaction between areas. Maps can be elaborated at different scales, from the neuronal level (micro) to the structural level of groups of neurons (macro). Findings about the anatomical and functional structures of brain connectivity are of great importance to better understand the functioning of the human brain, the relationship between neural activity and behavior, and the emergence and development of brain disorders.

III) Resting state fMRI (rsfMRI or R-fMRI) – This is a functional neuroimaging method that can be used to examine and assess how brain regions interact when human beings are not involved in specific tasks. Resting state activity can be observed with the fMRI by measuring the changes in the blood flow. As cerebral activity always stays on, each brain area shows spontaneous fluctuations in the fMRI signal. Thus, analyses of rsfMRI are essential to study the brain functional organization as well as its pathological alterations.

IV) Pain – Pain is a complex phenomenon, encompassing both sensory and emotional features. In its chronic form it is a dysfunctional response that persists well after the acute phase; it therefore heavily affects the quality of life. The study of acute and chronic pain can be carried out with a combination of different tools and experimental approaches (e.g., neuroimaging and lesional studies). The aim of Dr. Cauda’s research about pain is to better understand the brain mechanisms regulating the response to painful stimuli in both healthy and pathological subjects as well as the mechanisms regulating the intensity of these responses.

V) Complex neural systems – This research field focuses on creating mathematical models that integrate anatomical, neuroimaging, and genetic data. The construction of these models allow a better understanding of brain functioning and pathophysiology in terms of neural networks. Findings in this research field are essential to study the degree of susceptibility of different brain areas within networks to pathological damage.

VI) Voxel-based meta-analysis – The increasing number of fMRI and VBM investigations makes now possible to perform meta-analyses that combine data coming from a wealth of studies. By using specific statistical tools we can not only single out better the information of fMRI data but also infer the parameters of brain connectivity (e.g., MACM) from data that were not originally obtained for such use.

 

Tommaso Costa

Dr Tommaso Costa’s research focuses on:
I) Statistical mechanics of neural networks and their computational properties. Statistical mechanics is a tool developed by physicist that permit to describe system composed by many elements like gas. In the past Hopfield (1982) describe a neural network with associative memory properties using the tools of the statistical mechanis. In particular he found a form of the energy of the system. Aim of this project is to develop further the model and utilize it for detecting functional connectivity in fmri data.

II) Analysis of random walk and diffusion models of biological signals.
Aim of the project is to investigate the nature of the biological signal, in particular the BOLD signal to investigate the intrinsic properties of signal itself. We used the tool of the random walk for the analisys of the BOLD signal and we examine the functional difference of the different signal in the brain areas. The advantage of this tool is the capacity to extract useful information also with non gaussian signal or patological one.

III) Investigation of the neural basis of emotions.
Since William James’s work on emotions a great debate was stirred about their nature. There are two principal theories: discrete emotion models and dimensional models. There is not a definitive answer to the debate. Aim of this project is to investigate the neural distinctive patterns of emotions using meta-analytic and experimental methods with a particulat eye to the network model of the brain.

IV) Development of statistical methods for the meta-analysis of fmri data.
Aim of this project is to develop new methods for investigating meta-analytic data. In particular we want to develop new techniques for: parcellation and identification of cluster of foci; machine method for signature of pathological or cognitive state in meta analitic data.

Karina Tatukarina

Dr. Karina Tatu received her master’s degree from the University of Turin with a thesis entitled Pathophysiology and neurocognitive consequences of hypopituitarism in acquired brain injury”. Currently she is completing her PhD at the University of Turin as member of the Clinical and Experimental Group for Functional Magnetic Resonance Imaging (GCS-fMRI), Koelliker Hospital of Turin. Dr. Karina Tatu’s research focuses on clinical applications of MRI with particular interests in multiple sclerosis, chronic pain and brain tumors. She is actively involved in structural and functional MRI data acquisition and analysis for research and clinical purpose (e.g. task related and rs-fMRI, DTI-tractography). She is interested in structural and functional connectivity, pathoconnectomics and brain mapping.


Andrea Nani

Dr Andrea Nani’s research focuses on understanding how the brain responds to damage. His research uses network analysis techniques and neuroimaging tools (i.e., functional magnetic resonance imaging, voxel-based morphometry, etc.) to investigate what brain areas are most affected by neuropathologies. There is in fact increasing evidence that brain impairment might follow both anatomically and functionally recognizable patterns of distribution, independently of the neuropathology taken into account. The investigations in this topic have produced a new field of neuroscientific research, which is called pathoconnettomics. Dr Nani earned a degree in Psychology with a thesis titled Clustering and decoding of brain structural alterations caused by neuropathologies. Previously he had earned a degree in Law Studies and a PhD in Philosophy. He is also very interested in Consciousness Studies, and on this topic he is actively involved in research on both the theoretical and clinical perspectives. He has co-authored and wrote two books, both published by Springer Verlag, about consciousness – titled Neuroimaging of Consciousness and Consciousness: Theories in Neuroscience and Philosophy of Mind, respectively – with international renowned authors (i.e., Prof. Andrea E. Cavanna, Prof. Hal Blumenfeld, Prof. Steven Laureys). Dr Nani is also currently a member of the Michael Trimble Neuropsychiatric Research Group, University of Birmingham and BSMHFT, Birmingham, UK, and has held from 2013 to 2014 a Research Associate post at the Department of Neuropsychiatry, College of Medical and Dental Sciences, University of Birmingham, UK.
