Paolo Massobrio was born in Genova, Italy in 1979. He received the M.S. degree in Biomedical Engineering (110 cum laude, dignity of press) and the Ph.D. degree in Bioengineering Materials Engineering and Robotics (curriculum: Bioengineering and Bioelectronics) from the University of Genova, Italy, in 2004 and 2008, respectively. Currently, he joins with the Neuroengineering and Bio-NanoTechnology Group (University of Genova, Italy), where he has a post doctoral fellowship. His research activities are in the field of the neuroengineering and they include both experimental and theoretical aspects. In particular, he is currently working on synaptic plasticity mechanisms in dissociated neuronal networks coupled to Micro-Electrode Arrays, computational models able to describe the coupling between microtransducers (both metal microelectrodes and FET-based devices) and neurons and the dynamics exhibited by large-scale neuronal networks. In this field, he is coauthor of more than 30 papers ... read more

Research activity

My research activities fit into the field of Neuroengineering, concerning both experimental and modeling aspects. Within this framework, my research interest are mainly focused on the following topics:

-       Computational models of large-scale neuronal networks

-       Engineered neuronal networks, and experimental studies on network dynamics and plasticity


-       Bioelectronic models of the neuro-electronic junction


Here below, a brief description of the main research topics is summarized.

§  Engineered neuronal networks and investigations on dynamics and plasticity

The possibility to design specific network architectures by “forcing” the neurons to follow pre-defined structures allows to obtain information on the synaptic interaction among neurons, on the interplay between dynamic and network topology, and the mechanisms underlying synaptic plasticity and learning. On this topic, during my PhD, I performed experiments on dissociated cortical neurons coupled to MEAs by applying specific protocols of electrical stimulation that induce changes in network dynamics. I found that the effects of these high-frequency protocols induce long-term network plasticity. In 2007-2008, in collaboration with Philips (Eindhoven, The Netherlands) to understand the interplay between neural dynamics and connectivity, I developed an in vitro system for the study of the interactions between the cortico-thalamic neurons. More recently, we develop a new experimental protocol for culturing in vitro 3D networks coupled to MEAs and investigate how a 3D organization can shape the emergent dynamics. In addition, to characterize the dynamics and the related neural connectivity, in collaboration with the University of Torino (Italy), I performed experiments with neurons of invertebrate (Helix aspersa). Networks of neurons of Helix were designed and coupled to MEAs; by exploiting the big dimension of the somata of such neurons, a one-to-one coupling was achieved and two aspects were investigated: the dynamics expressed by the different families of Helix neurons in a network context and the emerging functional connectivity.

§  Computational models of neuronal assemblies

To model the dynamics of neuronal networks, I followed two different approaches: i) networks made up of a low number of neurons, whose activity has been described with accurate models (e.g., Hodgkin and Huxley); ii) large-scale networks (high number of neurons, complex connectivity rules) made up of point neurons with reduced models (e.g., Izhikevich equations). The common factor of these simulations is to understand the interdependence between connectivity and emerging dynamics. Neuronal networks can be ascribed to the category of complex systems, given the presence of numerous elements, such as the non-linearity of the interactions, the appearance at the global level of emergent properties without a similar microscopic, and not least the ability to self-organize. It has been found that a critical state is the key point for understanding the properties of plasticity and self-organization of the nervous system. By exploiting a modeling approach, I tried to correlate the critical behavior with the underlying network topology: the most important achieved result is that a temporal power-law behavior can be induced by a scale-free connectivity.

§  Bioelectronics models of the neuro-microtransducer interface


The recording of electrophysiological signals by extracellular electrodes is possible by the presence of a coupling circuit between the neuronal membrane and the recording device. During the first years of my research activity, I developed different circuit models of neuro-electronic junction for active devices (FET-based) and passive devices (metal microelectrodes and microelectrode arrays). Finally, the effects that the deposition of a layer of carbon nano-tubes (CNT) produce on the recorded signal was modelled.
